“MT4 (MQL4) EA Build — Two-Sided Ladder + AutoCorrect + BE + Unwind (Locked/Unlocked) (Majors + Crypto)”

Scope

Build a new EA from scratch implementing my provided strategy rules exactly. Deterministic, one logical action per tick (close OR place OR modify OR delete). Two-sided system (BUY + SELL). Includes stacking/maintenance, hygiene (pending correction), reduction closes, breakeven close logic, and a final termination/unwind mode.

Iteration workflow (LOCKED / UNLOCKED)

. Developer must maintain two copies/branches:

• LOCKED baseline v1.0 (frozen after acceptance)

• UNLOCKED experimental (future changes applied here only, versioned v1.1+)

Inputs (extern/inputs required — majors + crypto like my existing EA)

• InpSymbolFilter (string, empty = chart symbol)

• InpMagicNumber (int)

• InpSlippagePips (int)

• Lots:

  • InpAnchorLotMajors , InpStackLotMajors

  • InpAnchorLotCrypto , InpStackLotCrypto

• Grid step:

  • InpGridPipsMajors (pips → must convert correctly for 5/3-digit symbols)

  • InpGridDollarCrypto (absolute price units for crypto, e.g. BTCUSD $50)

  • Example: majors InpGridPipsMajors=10 (10 pips); BTCUSD InpGridDollarCrypto=50 ($50)

• Spreads:

  • InpMaxSpreadPipsMajors

  • InpMaxSpreadCryptoDollar

  • InpEnableSpreadGuard (optional)

Spread rule (important)
Spread is already accounted for in the strategy’s expenses/costs. If enabled, spread guard may block entries/modifies (and optionally initial anchor placement) but must never block closures (any reduction/BE/terminate actions).

Pending policy (equity control)

• Max 5 active ladder market trades per side (cap remains 5)

• Maintain only 2 pending orders per side at any time (depth-aware; no jumping to deepest early)

Logging / alerts (non-spam)
Must log every EA action (place/modify/delete/close/state change) but no per-tick spam. Only action/state-transition logging.

Deliverables

• .mq4 source + compiled .ex4

• brief run notes + input defaults

• Strategy Tester evidence (logs) showing rules are met

How bidders qualify (required reply)
To receive the full spec, confirm:

1. You will follow my spec verbatim and will not “improve” logic without approval

2. You understand one-action-per-tick architecture

3. You can implement 2-pending depth-aware maintenance with 5-market-trade cap

4. You will implement non-spam action logging

5. Provide 2–3 examples of MT4 EA work (profile links)

Milestones

1. Framework + order classification + non-spam logging skeleton

2. Anchors + ladder placement/maintenance + 2-pending rule

3. Hygiene correction + reduction close logic

4. Breakeven + terminate/unwind mode + failovers + final polish
