Custom MT5 Expert Advisor with Source Code (.mq5) based on Indicator

I need a professional Expert Advisor (EA) for MetaTrader 5 with the following requirements:

1. Source code (.mq5) must be delivered (not only .ex5).

2. Trading logic:

   - The EA should take signals from an indicator (e.g. IQ Gold Gann Levels or similar).

   - Buy = long signal, Sell = short signal.

   - Timeframes: M15 and H1.

3. Risk Management:

   - Maximum loss per trade: 100 € (lot size auto-calculated).

   - Profit target per trade: +200–300 € (TP = RR 2.0–3.0).

   - Fixed Stop Loss and Take Profit.

   - Maximum 3–5 trades per day, but minimum 2.

4. Optional filters (must be switchable on/off):

   - EMA200 trend filter (only Buy above EMA200, only Sell below).

   - ATR filter for volatility (min/max ATR).

   - Session filter (e.g. 08:00–22:00 CET).

5. Other requirements:

   - EA must work in Strategy Tester (backtest-capable).

   - Clear input parameters (risk per trade, RR, session times, filters).

Budget: 150–500 USD (depending on complexity).

Deadline: 7–14 days.
