Recommended Raw ECN Broker

The Impossible Bullion has been extensively tested across multiple broker conditions. For live raw-ECN execution on XAUUSD, we recommend RoboForex for tighter pricing and cleaner execution with this strategy profile.

Open Recommended Raw ECN Broker (RoboForex)

Configure and test your own profile using the parameter reference below. Product support is available through MQL5 comments or private message; this guide focuses on explaining the settings rather than supplying broker-matched files.

Starting Point

When examples below do not specify an environment, assume a raw / ECN retail-style baseline with tight spread and commission pricing. That is the cleanest starting point for Bullion because spreads are tighter, fills are cleaner, and spread-related filters can stay more selective.

RoboForex ECN Demo Test Set (2026)

Download the attached robo_market_200_bboff_buyblock55_2026.set file from this blog post. It was tested on RoboForex ECN XAUUSD M5, but can also be loaded as a starting point with other brokers and prop accounts. Demo users can open MT5 Strategy Tester, select The Impossible Bullion on XAUUSD M5, choose Inputs > Load, and select the downloaded .set file. Use Every tick based on real ticks and select deposit currency rather than profit in pips when comparing monetary results.

The set uses 2% risk per trade, a minimum entry score of 83, an ATR ceiling of 0.10% and a 200-pip maximum range. It turns off the Bollinger exhaustion block, keeps RSI scoring bands at BUY 50–60 and SELL 30–40, and blocks BUY entries when RSI reaches 55 or higher. Prop-firm mode and standalone daily/total drawdown stops are off; the MT5 calendar news filter is enabled but does not operate in Strategy Tester. Do not use this 2% risk setting on a funded or prop account without adapting it to your own limits.

For another broker, review the symbol specification, typical spread, commission, session hours and lot sizing before testing. For a prop account, configure its exact daily and total drawdown rules, risk per trade and trade caps; the supplied set does not enforce prop limits. Adjust the relevant inputs in the reference below, then backtest on your broker's data and demo-test the result. The same settings can behave differently across feeds, and the RoboForex result is not a performance guarantee elsewhere.

On RoboForex ECN real-tick data from 1 January through 28 September 2026, with a $100,000 USD test deposit. It was tuned for that environment and performed better there than unconfigured application defaults; a different feed, spread/commission profile, test window or modelling mode can change the result substantially. Run your own backtests and demo forward test before considering live use. The file is provided as a testing starting point, not a guarantee of returns or an offer of broker-matched set files.

Backtest mode reminder: Bullion's multi-window optimization tests used Every tick based on real ticks. Use real-tick mode for final validation when sufficient broker tick history is available; Every Tick or 1 Minute OHLC can speed up exploratory runs. Keep the broker feed, symbol, test dates, and inputs consistent when comparing results.

Strategy Tester: Validate Your Configuration

Save your chosen inputs as an MT5 .set file and reload it for repeatable Strategy Tester runs. This checks your configuration against the selected symbol, timeframe, and broker data; the MT5 Economic Calendar news filter is unavailable in Strategy Tester.

Step	What to do	Why it matters
1	Select The Impossible Bullion on XAUUSD M5 in Strategy Tester	This is the documented baseline; confirm your broker's symbol name and timeframe.
2	Load your saved .set file in Inputs	Ensures repeat runs use your intended configuration, not terminal defaults.
3	Use Every tick based on real ticks when broker tick history covers the test window; use Every Tick or 1 Minute OHLC for quicker exploratory passes	Real ticks provide the recorded tick sequence; consistent broker history and settings are essential for repeatable comparisons.
4	Run an in-sample and out-of-sample window, then compare trade quality and DD behavior	Checks profile stability, not just one period's headline result.
5	Only change one major parameter at a time, then re-test	Multiple simultaneous edits create a new unvalidated strategy profile.

Using Real Ticks for Bullion Validation

Bullion's weekly regime filter reads completed W1 data from MT5 history to decide directional gating and trade permission. The available history and broker's weekly session boundaries can affect those values, so load sufficient W1 history and keep broker, symbol, and date range consistent when comparing runs.

Every tick based on real ticks is a supported final-validation mode; Bullion's multi-window optimization tests used it. The former blanket advice to avoid real ticks was too strong. Every Tick and 1 Minute OHLC remain useful for faster screening, but modeling modes are not interchangeable. The MT5 Economic Calendar news filter is unavailable in Strategy Tester regardless of the selected mode.

Environment	Use when	Main adjustments
Raw / ECN retail baseline	Tight spread XAUUSD, commission model, no prop DD rules	Moderate MaxSpread, PropFirm OFF, static risk, tighter spread filtering
Wider raw retail	Still commission-based, but spread spikes more often	Raise MaxSpread modestly, keep SpreadMultiplier realistic, re-check trailing profile
Standard 10/5 challenge-style prop	Typical 10% max / 5% daily rule set	Enable PropFirm, set PropMaxDD / PropDailyDD correctly, use conservative risk and trade caps
Stricter 6/3 prop	Narrower 6% max / 3% daily rule set	Lower risk, earlier Yellow / Red zones, stricter spread acceptance, more conservative trade frequency

Spread, Execution, And Rule Mapping

Spread Calibration

Observed XAUUSD conditions	Typical approach	What usually changes
Very tight raw / ECN	Keep entry filter selective	Lower MaxSpread, lower tolerance for random spread spikes
Acceptable but wider raw	Allow slightly more entry tolerance without normalising bad execution	Raise MaxSpread moderately, keep SpreadMultiplier realistic
Standard-spread account	Not preferred for Bullion	Re-test before use; wider spread often requires materially different TP / SL behavior and lower expectancy

Do not raise MaxSpread just to force more trades. If valid trades are being blocked, first confirm your real spread distribution during Bullion's trading hours. A spread filter that is too loose can turn a carefully tested configuration into a low-quality execution profile.

Prop Rule Calibration

Rule style	Key inputs to review	Notes
Standard 10/5 challenge-style	EnablePropFirm, PropMaxDD, PropDailyDD, PropDDMode, Yellow/Red/Dead thresholds	Use the exact daily / total DD rules published by your firm, not a brand name assumption
Stricter 6/3 prop	Same inputs as above, with lower risk and earlier zone tightening	Usually requires lower risk-per-trade and tighter trade-frequency discipline
Trailing DD floor	PropDDMode=DD_TRAILING_HWM	Use only if the firm truly ratchets the DD floor with peak equity / balance
Static start-balance DD floor	PropDDMode=DD_STATIC_INITIAL	Most common choice for standard challenge accounts

Settings Reference

The tables below explain what each group of parameters does and how to think about the trade-offs. They are configuration notes, not optimisation promises.

New in v3.41: RSI Entry Configuration

RSI contributes up to 25 points to the strategy confirmation score; it is not a standalone entry signal. The score bands tune how RSI confirms a buy or sell setup. The optional hard block is independent and can reject an exhausted breakout even when the other entry conditions pass.

Parameter	Default	What it does / how to configure it
RSIScoreBuyMin / RSIScoreBuyMax	55 / 72	Buy RSI band. RSI inside this range earns full RSI confirmation; values outside it receive a reduced or neutral component.
RSIScoreSellMin / RSIScoreSellMax	28 / 45	Sell RSI band. RSI inside this range earns full RSI confirmation; values outside it receive a reduced or neutral component.
BlockExtremeRSI	false	When enabled, rejects buy or sell breakouts that meet the corresponding hard-block threshold. Leave off to use RSI only as a score component.
RSIHardBlockBuyAbove	72	With BlockExtremeRSI enabled, blocks buys when RSI is at or above this value.
RSIHardBlockSellBelow	28	With BlockExtremeRSI enabled, blocks sells when RSI is at or below this value.

Start with the defaults, then adjust one boundary at a time and compare in-sample and out-of-sample results. Keep the score bands distinct from hard-block behavior: changing a score range changes confirmation points, while enabling the hard block prevents qualifying entries altogether.

1. Strategy Core

Parameter	What it changes	Practical guidance
Timeframe	Chart timeframe Bullion reads for entry logic	Use XAUUSD M5. Do not treat other timeframes as equivalent.
LookbackBars	Size of the breakout range window	Lower values react faster; higher values need more structure before breakout.
BufferPips	Distance beyond the range required before entry qualifies	Raise it if you want fewer, cleaner breakouts; lower it if entries are too delayed.
MinRangePips	Minimum range size required to consider the setup valid	Raise it to avoid compressed sessions; lower it only if you have tested thin-range behavior carefully.
MaxRangePips	Upper limit on range size	Usually left wide. Lower only if extremely expanded pre-breakout sessions are polluting entries.
MinScoreToTrade	Primary quality threshold for Bullion's scoring engine	One of the most sensitive settings. Raising it usually reduces frequency and can improve selectivity; lowering it usually increases activity and noise.
MaxScoreToTrade	Optional upper band limit	Normally leave at 0 (off). Useful only for research or band testing.

2. D1 Gate And D1 Classifier

Parameter	What it changes	Practical guidance
RegimeGateEnabled	Enables the lightweight D1 ADX chop gate	Good first layer if you want simple chop rejection before enabling the full D1 classifier.
RegimeGateTF	Timeframe used for the gate ADX	Leave at D1 unless you are deliberately researching a different regime horizon.
RegimeGatePeriod	ADX period for the simple gate	Higher values smooth more; lower values react faster and can flicker more.
RegimeGateMinADX	Minimum ADX needed for entries to stay open to new trades	Raise it to block more choppy days; lower it to allow more marginal regimes.
RegimeClassifierEnabled	Enables the full 5-factor D1 regime classifier	More advanced than the simple gate. Best enabled only after observation and logging.
RegimeClassifierMode	0=diagnostic, 1=block chop, 2=direction-aware	Use diagnostic first if you are not sure how the votes behave on your broker feed.
RegimeAdxTrendMin	ADX threshold for trend vote	Raise for stricter trend recognition; lower for more permissive trend votes.
RegimeAdxChopMax	ADX threshold for chop vote	Higher values classify more days as chop; lower values require cleaner trendlessness before blocking.
RegimeAtrPctMax	ATR % ceiling used inside the classifier	Controls how stretched daily conditions are interpreted. Do not change casually.
RegimeDiagCSV	Writes classifier diagnostics to file	Recommended before enabling live blocking in a new environment.
MaxHoldBars	Maximum bar duration for any open trade	Useful if you want to prevent extended holds on M5.
CooldownBars	Pause between trades after a close	Useful to suppress rapid re-entry loops in volatile periods.

3. Session Filter

Parameter	What it changes	Practical guidance
SessionStart / SessionEnd	Main trading window in GMT	Use the liquid part of the day for XAUUSD. All-hours configurations typically sit around London through New York.
ExcludeStart / ExcludeEnd	Optional sub-window inside the main session where entries are suppressed	Use only if your testing shows a reliably poor intraday pocket.
BlockMonday ... BlockFriday	Per-day trading switches	Useful if one weekday is consistently weak on your broker feed.

Bullion supports SessionStart > SessionEnd for overnight windows that wrap midnight. That allows one continuous session without splitting into two charts.

4. Risk

Parameter	What it changes	Practical guidance
RiskPerTrade	Percent of equity risked per trade when using dynamic sizing	Lower it first on prop accounts. This is the first place to reduce aggression.
CompoundAggressive	Whether sizing compounds with current equity	Leave on for normal compounding; turn off if you want steadier sizing relative to start balance.
FixedLots	Overrides risk-based sizing with a fixed lot size	Use only if you intentionally want manual lot control.
MinLotSize / MaxLotSize	Caps on calculated position size	Important for very small or very large accounts.
MagicNumber	Unique trade identifier	Change when running multiple Bullion instances on one terminal.

5. TP / SL And Spread

Parameter	What it changes	Practical guidance
TP_Pips	Fixed take-profit distance	One of the core expectancy settings. Do not alter without re-testing the full exit profile.
SL_Pips	Fixed stop-loss distance	Must be considered together with trailing and breakeven behavior.
MaxSpread	Hard entry block above this spread level	Match this to your real XAUUSD spread distribution. Too high usually harms quality more than it helps activity.
SpreadMultiplier	Minimum-stop safety buffer relative to spread	Higher values are more conservative. Use realistic values for ECN/raw execution.

6. ATR Scaling

Parameter	What it changes	Practical guidance
UseATRScaling	Replaces fixed TP / SL with ATR-based values	Leave off unless you are intentionally building and testing a volatility-adaptive profile.
SL_ATR_Mult	ATR multiplier used for stop-loss	Lower = tighter stop; higher = more room.
TP_ATR_Mult	ATR multiplier used for take-profit	Usually kept above the SL multiplier to preserve a healthy reward structure.

7. Trade Management

Parameter	What it changes	Practical guidance
UseBreakeven	Moves stop after price reaches a trigger	Can reduce left-tail risk, but can also cut good trades too early if the trigger is too tight.
BreakevenTrigger	Profit distance before breakeven activates	Lower values protect earlier but often reduce follow-through room.
BreakevenOffset	Offset beyond entry after breakeven fires	Useful if you want small locked profit instead of exact flat break-even.
UseTrailingStop	Enables trailing stop management	One of Bullion's most important exit tools.
TrailingStart	Profit distance before trailing begins	Lower = earlier protection; higher = more room for trade development.
TrailingStep	Distance maintained once trailing is active	Tighter values lock profit faster but can choke runners.
EnableTPExtension	Enables Progressive TP Extension	Bullion-exclusive feature. Useful when strong moves regularly push beyond the first TP.
ExtendTPTriggerATR	How close price must get before extension logic arms	Lower values trigger later; higher values trigger earlier.
ExtendTPByPips	How far TP is pushed each time	Larger steps chase bigger runners but can also delay realization.
ExtendTPMaxCount	Max number of TP extensions	0 means unlimited.
ExtendTPRatchetSL	Whether SL is shifted when TP extends	Mainly useful if trailing is off and you still want additional protection.

8. Protection

Parameter	What it changes	Practical guidance
MaxDrawdown	Total account-level halt threshold	Set it to your personal or firm risk ceiling.
MaxDailyLoss	Daily halt threshold	Critical for funded or challenge-style accounts.
MaxOpenTrades	Maximum concurrent positions	Default one-trade structure is the safest baseline.
MaxTradesPerDay	Daily trade cap	Use to prevent overtrading during noisy sessions.
MaxConsecLosses	Daily stop after a losing streak	Useful if the strategy degrades sharply once regime quality falls.

9. News Filter

The MT5 Economic Calendar supplies event times, currencies, names, and impact. When EnableNewsFilter is on, Bullion blocks new baskets around matching high-impact events; it does not close an existing basket. With the filter off, the dashboard can still monitor calendar events. A matching event must pass both the currency and keyword filters.

Parameter	Default	What it changes / practical guidance
EnableNewsFilter	false	Enables entry blocking around matching high-impact events. Leave off for dashboard monitoring without blocking.
NewsMinutesBefore / NewsMinutesAfter	30 / 15	Blackout minutes before and after an event. Widen these windows only if your feed remains unstable around releases.
NewsCurrencyWhitelist	USD	Comma-separated event currencies. Empty uses the chart symbol's base and profit currencies.
NewsKeywordWhitelist	CPI,NFP,FOMC,PCE,POWELL,GDP,PMI	Comma-separated text matched against event names. Empty accepts every event name that passes the currency filter.
ShowNewsPanelSection	true	Shows or hides the dashboard's NEWS section.
ShowUpcomingNewsInfo / NewsLookaheadMinutes	true / 1440	Shows the next matching event and sets how far ahead the panel searches.
NewsPanelMinImpact	Moderate	Controls the minimum impact shown in the panel; entry blocking still checks high-impact events.
NewsPanelVerbosity	Detailed	Choose compact or detailed dashboard rows. Currency and event-name display can also be toggled.
NewsPanelRefreshSeconds	20	Sets the calendar-panel refresh interval; the minimum effective interval is 5 seconds.
NewsAlertLeadMinutes	20	Minutes before an upcoming event to issue alerts; set to 0 to disable the lead alert.
EnableNewsPopupAlert / EnableNewsPushAlert / EnableNewsSoundAlert	false	Optional terminal popup, push, and sound alerts before matching events.

The panel reports whether an event is near and shows the next event within the look-ahead window. Currency and keyword lists are comma-separated; matching is case-insensitive. The calendar is unavailable in Strategy Tester, so validate the filter and alerts on a demo or live terminal with calendar access.

10. Shield

Parameter	What it changes	Practical guidance
EnableShield	Enables the equity-peak circuit breaker	Useful when you want the EA to stand down after giving back too much from a peak.
ShieldArmPct	Profit milestone before Shield fully arms	Higher means Shield waits longer before becoming active.
ShieldDrawdownPct	Drawdown from shield peak that triggers it	Lower values protect faster; higher values allow more giveback.
ShieldRecovery	0=permanent, 1=next day, 2=recovery-based reset	Choose the reset style that matches your account management rules.
ShieldRecoveryPct	Required recovery before re-enable in recovery mode	Only used when ShieldRecovery=2.

11. Prop Firm Mode

Parameter	What it changes	Practical guidance
EnablePropFirm	Turns on zone-based risk control	Enable only when the account is actually governed by explicit DD rules.
PropMaxDD / PropDailyDD	Maximum total and daily DD limits	These must match your actual firm rules exactly.
PropYellowPct / PropRedPct / PropDeadPct	Thresholds for zone changes	More conservative profiles move into Yellow and Red earlier.
YellowRiskMult / RedRiskMult	Risk reduction inside warning zones	Lower multipliers reduce size more aggressively as DD budget is consumed.
YellowMaxTrades / RedMaxTrades	Trade cap overrides in warning zones	Useful for cutting trade frequency as the account approaches limits.
YellowMinScore / RedMinScore	Minimum score floors inside warning zones	Raise to demand cleaner setups while under stress.
PropStartBalance	Reference start balance for DD calculations	Leave at 0 for auto-history reconstruction unless you specifically need manual override.
PropDDMode	Static or trailing DD floor	Use the firm's actual rule wording, not marketing shorthand, to choose the mode.

12. Weekly Regime Filter

Parameter	What it changes	Practical guidance
EnableRegimeFilter	Enables W1 trend detection	Core Bullion filter. Normally left on.
RegimeEMAPeriod	Weekly EMA period used by the filter	Lower reacts faster; higher smooths more.
RegimeLookback	How many W1 bars are used for slope reading	Higher values create a slower, more stable trend state.
RegimeMinSlope	Minimum slope magnitude to classify trend	Raise it to avoid weak-trend classification; lower it to accept softer trend states.
TrendMode	How trade direction is allowed relative to the weekly trend	Bullion-specific directional control. Use the mode matrix below for weekly UP, DN, and FLAT behavior.

Mode	Weekly trend UP	Weekly trend DN	Weekly FLAT
TREND_BOTH	Buys & sells	Buys & sells	Buys & sells
TREND_WITH_ONLY (default)	Buys only	Sells only	Buys & sells
TREND_WITH_SKIP_FLAT	Buys only	Sells only	No trades
TREND_BUY_ONLY	Buys only	Buys only	Buys only
TREND_SELL_ONLY	Sells only	Sells only	Sells only

TREND_WITH_ONLY is the default for Bullion. Use TREND_BOTH if you want Gold-style both-direction behavior, TREND_WITH_SKIP_FLAT if you want the EA to stand aside when the weekly trend is unclear, and TREND_BUY_ONLY / TREND_SELL_ONLY for pure directional overlays.

13. Additional Prop Filters

Parameter	What it changes	Practical guidance
EnablePropFilters	Master switch for the additional prop-only filters	Useful when you want extra protection beyond the normal score and regime stack.
FilterCounterTrendH1	Blocks entries against H1 EMA50 slope	Can reduce counter-trend exposure, but may also cut valid reversals.
FilterMinADX	Blocks low-ADX entries	Use with care; it can overlap with other trend-strength filters.
MinADXForEntry	ADX threshold used by FilterMinADX	Higher values allow only stronger momentum states.

14. Audit, Direction Exclusions, Discord, And Display

Parameter	What it changes	Practical guidance
LogTradeFactors	Writes per-trade score audit CSV	Enable when diagnosing why trades did or did not happen.
AuditCSVPrefix	Sets the audit filename prefix	Useful when separating logs by environment.
BuyExcludeStart / End	Suppresses buys during selected GMT hours	Use only if a directional intraday bias is consistently poor on your broker.
BuyExclude2Start / End	Second buy exclusion zone	Use if you need two separate buy-suppression windows.
SellExcludeStart / End	Suppresses sells during selected GMT hours	Same logic as buy exclusions.
DiscordWebhookURL	Main Discord webhook	Blank disables alerts.
DiscordRecapWebhookURL	Optional separate recap webhook	Leave blank to reuse the main webhook.
DiscordAlertOnOpen / Close	Trade event alerts	Normal live-monitoring settings.
DiscordWeeklyRecap	Monday performance recap	Useful for VPS-based unattended monitoring.
DiscordStartupPing	Startup confirmation message	Strongly recommended for VPS setups.
SetDescription	Instance label shown on dashboard and in alerts	Important if you run multiple Bullion charts.
ShowDashboard	Shows the on-chart panel	Usually left on.
ShowChartExtras	Extra overlays and labels	Personal preference unless you want a cleaner chart.
ShowATRWarning	Displays elevated daily ATR warning	Recommended on.
DebugMode	Verbose logging	Use only when troubleshooting.

Example Configuration Logic

Situation	Usually review first	Why
Broker spread is tighter than expected	MaxSpread	You may be able to keep entry quality tighter without losing valid trades.
Broker spread is wider than raw baseline	MaxSpread, SpreadMultiplier, TP / SL behavior	Do not simply lift MaxSpread aggressively; confirm the entire exit structure still makes sense.
10/5 challenge account	EnablePropFirm, PropMaxDD, PropDailyDD, PropDDMode, risk, trade caps	The rule framework matters more than brand naming.
6/3 account	Same as above, but with lower risk and earlier zone tightening	Narrower DD tolerance requires faster defensive behavior.
Too many low-quality entries	MinScoreToTrade, RegimeGateEnabled, RegimeClassifier	Raise selectivity before touching exits.
Too many trades in poor intraday pockets	Session window, exclusion hours, weekday blocks	Time-of-day filtering often fixes this more cleanly than changing score thresholds.
Good trades stop out too early	TrailingStart, TrailingStep, breakeven, SL structure	Exit logic is usually the issue, not entry logic.

Deployment Checklist

1. Attach Bullion to XAUUSD M5
2. Confirm broker symbol, digits, and spread behavior
3. Set your core environment: retail raw, wider raw, standard 10/5 prop, or stricter 6/3 prop
4. Verify PropDDMode against the firm's actual rule wording if funded / challenge
5. Set a unique MagicNumber and meaningful SetDescription
6. Configure Discord webhook if you want live monitoring
7. Demo test for 2 to 4 weeks
8. Only then move to live or funded deployment

Final Notes

This guide explains how to configure Bullion intelligently. It does not replace broker-specific or rule-specific testing. The same EA can behave differently across feeds because spread, slippage, execution style, and DD rules materially affect the realised profile.

For product or configuration support, use MQL5 comments or send a private message to the seller. For community setup discussion and release updates, use the Discord details linked near the top of this guide.
