Expert Advisor for ORB-Strategy

I am looking for an experienced MQL5 developer to build a fully configurable MT5 Expert Advisor for an Opening Range Breakout (ORB) system. The EA must support multi‑asset, multi‑session (EU/US/Asia), and multi‑timeframe trading with independent engines for M1 and M5 (1 trade per session per timeframe).

Requirements:

• Williams‑Triangle based range detection (2‑candle confirmation)

• Breakout entries with offset

• Risk‑based lot calculation

• TP including spread‑offset (2–3 points)

• Optional: max‑range per asset, MACD/ATR/Spread filters, swing‑trailing

• Per‑asset session selection + weekday filters

• Two MagicNumbers per asset (M1/M5)

• Full logging + stable error handling

Delivery: 3 days Testing: 10 days demo before acceptance Support: 1‑month bug‑fix guarantee Budget: 100 USD+
