MT5 EA Developer – Multi-Symbol MTF Trend System + Portfolio Risk Engine (Private Rules / NDA Required)

I am looking for an experienced MT5 developer to code a multi-symbol, multi-timeframe, rule-based trend system with a portfolio risk engine.

⚠ Important:

The complete strategy logic already exists and is fully backtested.

I will not share the rules publicly.

Full specifications are provided privately after NDA agreement.

⸻

1. Strategy Logic (high-level)

(Full details provided privately after NDA)

The EA must implement a rules-based system using:

• Multi-timeframe indicators

• Trend filtering

• Momentum / pullback filtering

• Strict, mechanical entry and exit rules

• Fixed stop-loss and take-profit logic

No optimisation or idea creation is needed — this is 100% implementation of an already finished strategy.

⸻

2. Execution Requirements

The EA must:

✔ Trade multiple symbols from a single chart

✔ Use the same logic per symbol

✔ Have enable/disable inputs per symbol

✔ Only allow 1 active trade per symbol

✔ Prevent duplicate entries on the same bar

✔ Use market orders only

✔ Assign unique magic numbers per symbol

✔ Be scalable so I can add more symbols later

Symbols required (initial):

• XAUUSD

• NAS100

• SPX500

• GER40

• JP225

Additional symbols may be added later.

⸻

3. Risk Management Requirements

I need portfolio-aware risk management, not just lots.

Per-Trade Risk

• Global risk % per trade

• Per-symbol risk overrides

• Position size auto-calculated from SL distance

Portfolio Drawdown Limits

• Daily DD limit → disable new entries until next day

• Total DD limit → fully pause EA until manual restart

Optional:

• Per-symbol DD limits (disable only that market)

⸻

4. Safety Requirements

• Optional session filter

• Optional news filter (if you have a standard method)

• No grid / martingale / averaging down

• Handle:

• Trade context busy

• Requotes

• Slippage

• Partial fills

• Order send/modify errors

The EA must “fail safe” and retry logically.

⸻

5. Logging & On-Chart Info

I need clear logs for:

• Entry attempts (symbol, lot, reason)

• Exit events (TP, SL, condition change, DD filter)

• Trade errors with error codes

On-chart panel/Comment showing:

• Equity & balance

• Open trades count

• Daily DD %

• Total DD %

• Trading status (active / DD paused / session filter paused)

The panel can be simple — clarity over aesthetics.

⸻

6. Inputs Needed

At minimum:

• Global_Risk_Per_Trade (%)

• Per-symbol risk overrides

• Enable/disable switches per symbol

• Daily DD limit

• Total DD limit

• Session filter times

• Magic number base or per-symbol magic numbers

• Order comment/tag

• News filter on/off (if implemented)

⸻

7. Confidentiality / IP Protection

Please confirm:

1. You will not reuse, resell, or share this logic.

2. You agree to NDA before receiving details.

3. Upon delivery you will provide:

• The compiled EA (.ex5)

• And optionally the source (.mq5) ONLY for my private use (not redistributed).

4. You are willing to provide minor fixes after delivery.

⸻

8. Developer Questions — Please Answer Briefly

1. Your experience with multi-symbol MT5 EAs and portfolio risk systems.

2. How you typically protect client strategy logic and IP.

3. Estimated delivery time:

• First beta version

• Final version after testing

4. Fixed price for the full project.

5. Examples of previous MT5 EAs you have built (descriptions or screenshots only).
