PARAMETER GUIDE

Complete description of all settings
| Recommendation: The default values are the ones used on the live account. Only change parameters if you understand the consequences. |
A — Strategy
| Panel default: true On-chart panel showing EA status, account figures, next lot and current spread. It also applies the Proxima chart theme and draws the session windows, the basket ladder and the volatility strip. Turn it off to leave your chart untouched. |
| Magic default: 1 Identifier of the EA's trades. Use a different number for each EA running on the same account. |
| OrderComment default: Proxima Tag shown in the order history. |
| MaxSpread, points default: 100 Entries are skipped while the spread is higher. Keep it above your broker's real Gold spread, otherwise the EA never opens a trade. |
| MaxSlippage, points default: 100 Maximum deviation accepted when an order is filled. Gold moves fast inside the trading windows, so a value that is too small leaves entries rejected. |
| MaxOrders default: 100 Global cap on positions held by the EA at any moment, across all baskets. A safety limit rather than a tuning parameter: the highest number reached in ten years of testing was thirteen. |
B — Lot Sizing
| FixedLot default: 0 (= auto) Manual lot for every entry. Any value above 0 overrides the risk level. Leave at 0 to let the EA size positions from the account balance. |
| RiskLevel default: Low Automatic position sizing. The lot grows with the balance: each risk level defines how much equity backs one 0.01 lot. All protection thresholds scale with the lot, so the risk profile stays the same as the account grows. Because the broker's minimum lot is 0.01, the levels only start to differ once the balance is large enough to ask for more than the minimum. Below that point every level trades 0.01. |
|
C — Trading Time
| Proxima trades inside fixed intraday windows tied to the broker's server time. The session windows themselves are part of the strategy and are not adjustable; the settings below only add extra pauses on top of them. |
| NfpFilter default: true Skips new entries on the first Friday of the month, when the US employment report is released. Baskets already open are managed as usual. |
| CloseFriday default: true Stops opening new baskets late on Friday, so no position is carried over the weekend gap. |
| CloseFridayHour default: 22 Server hour from which the Friday stop applies (0–23). Match it to your broker's server time, not to your local clock. |
D — Trading Days
| TradeMonday … TradeSunday default: true for every day Allows or blocks new entries on a given weekday. Blocking a day only stops new baskets; positions already open keep being managed until they close. The default is every day enabled, which is how the published results were produced. Disabling days removes trades from the strategy and changes its statistics. |
E — What runs without settings
| The parts below are calibrated and built into the EA. They have no inputs on purpose: changing them would change the strategy rather than tune it. |
| Volatility-scaled grid Positions are averaged on a ladder whose spacing follows ATR on H1. In quiet markets the ladder keeps its calibrated spacing; when volatility rises it stretches, up to one and a half times, so a fast move fills fewer levels. Within one basket the ladder can only widen, never tighten. |
| Two-step basket stop Every basket is protected in two stages. The first stage closes half of the volume and lets the remainder work toward the target with a lower average price. The second stage closes the basket entirely. Both thresholds are defined per 0.01 lot and scale with the position size, so the profile is identical on any account. |
| Daily circuit breaker If a basket is ever closed by the full stop, the EA closes every remaining basket and blocks new entries until the next server day. A bad day ends there instead of continuing. |
| Low-volatility entry gate Two of the strategies stand aside when ATR on H1 falls below the level where their target is no longer reachable. In the current gold regime this gate is practically never closed; it exists for a return to the quiet market of 2016–2019. |
| Portfolio stop An upper limit on the floating loss of all baskets together, independent of the per-basket stops. |
F — Setup notes
| Account type A hedging account is required: several baskets may be open at the same time. Leverage of 1:500 is recommended; margin never exceeded a small share of equity in testing, but a lower leverage reduces the head-room. |
| Symbol and chart Attach one instance to a single XAUUSD chart. The timeframe of the chart does not matter — the EA reads its own timeframes internally. If your broker uses a suffix such as XAUUSD+, use that symbol. |
| Server time All trading windows follow the broker's server time. A broker on a different server offset will trade different hours of the day, which changes the results. |
