We are looking for a professional developer for an EA grid martingale.

PROJECT DESCRIPTION

Looking for 1 experienced MQL5 developer to build 2 Expert Advisors for MetaTrader 5, targeting XAUUSD and major currency pairs. Strong preference for a single developer handling both EAs to maximize code reuse, reduce cost, and ensure consistency.

EA1 — Grid Martingale Pro

·       Buy/Sell grid with Fixed or ATR Dynamic distance (ATR read once per fill, stored in grid_step_at_open[])

·       Gap Protection: Market fill when price jumps past pending level

·       Trend Filter: CCI + SuperTrend + ADX — stop opening new grid on counter-trend signal

·       Exit logic: Net TP, Total TP, Trailing Stop, Hard Stop, Daily Drawdown

·       CCanvas Panel 4 tabs (built at M3): Trading / Grid Setup / TP-SL / Filter

·       Grid Preview: Fixed = exact entry price — ATR = 3-state display ✅📊❓

·       State persistence: survive VPS restart via file I/O

EA2 — Hedging Grid Martingale

Reuses EA1 codebase entirely. Developer only adds Hedging layer:

·       Place Pending on both sides (Buy Stop GU + Sell Stop GD) — determine direction when L2 fills

·       Rolling TP: winning side auto-closes each level TP, losing side holds (loss-hold)

·       BE_Net + BE_Total: draw 2 horizontal lines on chart — update realtime via OnTradeTransaction()

·       BE_Total = BE_Net − Realized / (net_lot × ContractSize)  [direct formula, no point conversion]

·       3 parallel exit conditions: Net TP / Total TP / Hard Stop (first triggered wins)

·       Hard Stop → STOP BOT (no auto-reset, awaits user intervention)

·       CCanvas Panel 3 tabs (built at M3): Trading+Info / Grid Setup+Exit / Filter

💰  PAYMENT — 3 MILESTONES

Payment split into 3 milestones. The agreed total is the net amount the developer receives — developer is responsible for all MQL5 platform transaction fees.

⚠️  Important: EA1 and EA2 must run fully without the Panel at M1 and M2. The panel is a UI overlay only — core logic must work independently via MetaTrader's Inputs tab. Developer must design internal variables (BE, grid state, trend status) to be panel-ready from M1.

✅  DEVELOPER REQUIREMENTS

·       3+ years MQL5 experience with completed EA projects on MQL5.community profile

·       CCanvas custom panel experience required

·       Must be comfortable with: iATR(), iCCI(), iADX(), OnTradeTransaction(), custom SuperTrend

·       English or Vietnamese communication is fine

·       Backtest video required at M1 and M2 — 'Every tick based on real ticks'

❌  DO NOT APPLY IF:

·       No completed projects visible on MQL5 profile

·       No CCanvas / custom UI panel experience

·       Unwilling to accept milestone-based payment
