Golden Zone OB Lock & Trail MT5 — v5.28

Golden Zone OB Lock & Trail MT5 is a proprietary Expert Advisor by William Kaumba Daka that trades from mapped order-block (OB) zones using a three-line trap—TOP, MED, and BOT—and then protects with a dynamic BE → lock → trail stack. OB bands are derived from swing structure with ATR-scaled offsets so the system adapts as volatility breathes.

Core trade logic

The engine maps internal/swing OB snapshots into a compact SMC model (bias + top/median/bottom), detects first-touches at those levels, and scores bull/bear sides independently using configurable weights per level. The final long/short gate requires threshold and side dominance. (Optional median line plotting is included for visual context.)

A Golden Band module lets you validate or re-base traps against a 61.8–78.6 zone from the most relevant swing (VALIDATE / INTERSECT / SNAP modes), with tolerance and minimum-overlap controls.

Execution: traps & orders

You can run “touch at market” or place real pending LIMIT/STOP orders at TOP/MED/BOT, with legality/orientation checks and caps per trap and per order. Maximum traps per side, offsets, and price tolerances are input-driven. Visuals are configurable, including a per-ticket toggle to prevent on-chart clutter.

Signals & filters

Signals can incorporate your fast/slow MAs, RSI, MACD, ATR, and a higher-timeframe look; a switch enforces inside-zone only entries so signals must occur inside the active OB. Asset-class presets adapt spread-vs-ATR gates, effective modify distances, and ATR scaling per instrument.

Risk, sizing & broker hygiene

Position sizing respects RiskPercent and normalizes lots strictly to broker min/step/max; a margin-fit routine can auto-shrink size to what the account can carry. A dynamic volume cap caches broker rejections to avoid repeat “too large” errors. Order-send paths are filling-mode aware (with a user-selectable filling mode and optional strictness), and symbol-class presets screen openings via spread/ATR before any trade is attempted.

Protection stack: BE → Locker → Trail

Break-even advances through 30% → 20% → 10% → 0% of original risk with ATR-gating, minimum-seconds spacing, optional one-stage-per-bar, close confirmation, and an optional re-engage that can reseed protection to a percent of original risk if trailing hasn’t locked enough yet. A hard BE floor can prevent any SL from drifting back below entry once BE is achieved.

The Pure Money Locker is the primary protector: it locks profit in cash steps tied to TP progress, with sticky/live TP anchoring, tick-sensitive minimums, and optional ATR hysteresis; the Monetary TP Trail runs as a smart backup (25/50/75% of TP cash) and defers when the Locker is already doing the job. All stop moves are unified and monotonic (no loosening), aligned to ticks, and pre-filtered by freeze/min-distance guards to avoid broker rejections.

News & LDN

News windows are pluggable: MT5 calendar, CSV, lightweight web probes, or Global Variables; you can cluster events, set look-aheads, and run a lightweight “Pro/LDN” workflow with a guarded attempts-per-window. (Legacy LDN hooks are present behind compile-time gates.)

UX & control

The EA exposes compact inputs for toggling trading and pause states, selecting trailing aggressiveness, managing positions across all symbol positions or just the EA’s magic, and switching trap visuals (including the per-ticket option). Optional SMC score labels assist quick read-outs.

What’s new in v5.28

Dual-tally SMC scoring. Bull and bear sides score independently with per-level weights; entries require threshold and side dominance. (Includes optional median plotting.)

Golden Band modes. Validate, intersect, or snap traps to a 61.8–78.6 band with tolerance and overlap controls.

Trap UI upgrade. Pending traps at TOP/MED/BOT with legality/orientation checks, per-trap lot caps, per-side limits, and a per-ticket visuals toggle to prevent clutter.

Asset-class presets (integrated). Spread-vs-ATR gating, effective min-distance multipliers, and ATR scaling vary by symbol class; guards screen opens before sending.

BE & protection refinements. Re-engage options, BE hard-lock at entry, money-locker “primary” with ATR hysteresis, and a monetary trail “backup” that defers appropriately—everything funneled through a monotonic UnifiedStop with freeze/min-distance prechecks.

Golden Zone OB Lock & Trail MT5 — Update
Release notes

New

ProNews one-press preset (tied to the LDN: ON button): auto news bias + MT5 calendar gating; new NEWS_GLOBALVARS mode reads LDN_NEWS_START/END.

Asset Manager presets (FOREX/METAL/CRYPTO/INDEX/ENERGY/SOFT): per-asset spread-to-ATR checks, effective min-distance & ATR scaling on entries/modifies.

Pure Money Locker (primary) + Monetary TP Trail (backup): locks profit in 5% TP steps with sticky/dynamic TP anchor and ATR hysteresis.

Break-Even engine v2: staged 30→20→10→0% with ATR gating, time/close confirmation, one-stage-per-bar, hand-off to trailing and optional re-engage.

Trap engine upgrades: optional real pendings at TOP/MED/BOT, per-trap execution caps, auto flip wrong pending type, zone visuals, compact TRP:<id> comments.

Robust order send: fill-mode rotation (IOC/FOK/RETURN), margin-fit, dynamic volume caps + side allowance guard, smart cooldowns.

Broker overrides (min lot, step, contract size) + “manage all symbol positions” switch.

GUI: LDN toggle, trailing CONS/AGG toggle, quick close buttons, live labels (composite & LDN scores).

Improvements

Unified stop modifier with monotonic only + hard BE lock; freeze-level and min-distance aware; millisecond debounce.

Pending safety: legal SL/TP vs pending price, tick alignment, one-tick cushion.

Auto seed of missing original SL (OB or 1.5×ATR) so BE math is always valid.

Synth TP anchor (3×ATR) so Locker can operate even w/o a set TP.

Fixes/Hardening

Stage-4 BE deferred until there’s real room vs broker min-distance (prevents SL < entry).

Avoid RETURN on market orders unless it’s the only allowed mode.

Better handling of volume-limit rejects (shrink & learn server caps).

News engine back-off; ProNews OFF clears windows & bias cleanly.

Quick-start inputs (change only these first)

Risk & basics

RiskPercent = 1.50 (start lower if needed)

MinLotUser = 0.01 (or your broker’s min)

TradeMagicNumber = unique per chart

AllowLongs/AllowShorts = true

MaxOrdersPerSide = 1

ShowUI = true

Stops & trailing (good defaults)

BE_HardLockAtBreakeven = true

PureLocker_Enable = true (primary)

MonetaryTPTrail_Enable = off (enable later if you want backup)

LDN_TrailingAggressiveness = LDN_TRAIL_CONSERV

Traps (optional to start)

EnableTraps = false (learn the EA first)
When ready: set true, keep Trap_PlacePendingsAtLines = false initially.

News

Easiest: leave NEWS_Mode = NEWS_GLOBALVARS (no gating unless you publish GVs).
Or set NEWS_MT5 to use the MT5 calendar.

Filling/broker

OrderFillingType = ORDER_FILLING_IOC

StrictMarketFill = true (especially in tester)

Leave broker overrides off unless your server misreports values.

Quick-start guide (5–7 minutes)

Attach the EA to a liquid symbol (e.g., EURUSD or XAUUSD) on your preferred TF. Default HTF = H4; LDN uses M30 internally.

Enable Algo Trading in MT5 and make sure the symbol is trade-enabled.

Set a unique TradeMagicNumber per chart/symbol.

Risk: tune RiskPercent (e.g., 0.25–1.0% while learning).

(Optional) News gating:

MT5 calendar: set NEWS_Mode = NEWS_MT5.

External windows: create MT5 Global Variables LDN_NEWS_START / LDN_NEWS_END (epoch seconds); EA will read them.

(Optional) Traps: when comfortable, set EnableTraps = true. Start with market-on-touch (leave pendings off).

GUI on chart:

Toggle Trading ON/OFF, Pause, Trailing CONS/AGG.

Click LDN: ON to enable the new LDN engine; this also applies the ProNews preset (auto news bias). Click again to turn it off.

Let it run. The EA opens only when entries are inside its OB “golden zone” (61.8–78.6) and confluence gates pass.

Watch logs with Diagnostics = true for clear reasons on skips/entries (spread/ATR, news windows, caps, etc.).

Backtest with StrictMarketFill = true and (optionally) DryRun = true for a quick safety shakedown.

Tips

Magic numbers: unique per chart; set ManageAllSymbolPositions = false unless you intentionally want to manage every position on the symbol.

Broker constraints: high freeze/stops levels? Increase BufferPoints or set UseATRInModifyMinDist = false to relax modify distance.

Volume limits: if you see “VOLUME LIMIT” messages, the EA will auto-shrink and learn caps. You can also lower risk or lots.

Pending orientation: if you enable pendings and get “Invalid price”, set Trap_AutoFlipToCorrectType = true or increase TrapOffsetPoints.

BE staging: stage-4 (true BE) only occurs when there’s enough room vs broker min-distance; this is on purpose.

Locker + Monetary: Locker is primary; Monetary acts as a backup when the locker lags your chosen stage.

News preset: turning LDN OFF clears the ProNews bias & news window; turning it ON re-primes the news scan.

Testing first: try DryRun = true for a live-like dry-run (logs only), then flip it off to go live.

Symbols: start with majors or XAUUSD; avoid illiquid exotics while tuning.

UI closers: “Close All/Longs/Shorts” respect your slippage setting (MaxSlippagePoints).
