■ Purchase / Licensing / Payments
Q1: Can I buy the EA with crypto or outside the MQL5 Market?
No. Purchases are available only through the official MQL5 platform. Any copy bought elsewhere cannot receive support, updates, or a valid activation.
Q2: Why does the EA price change?
The price auto-increases after certain sales thresholds (an official MQL5 feature). If you still see an old price, refresh your browser cache.
Q3: Do you publish Myfxbook or live forward results?
No official, continuously updated performance is published. We avoid selective disclosure that may be misleading. Please forward-test on a demo or a small real account yourself.
Q4: Do you offer direct support via Telegram, LINE, etc.?
No. All support is handled via MQL5 private messages or the buyers-only group chat.
Q5: Can I run the EA on a prop-firm account?
Yes, but verify each firm’s API, max-DD, and trading-style rules first.
■ Recommended Settings & Operation
Q6: Which pairs and timeframes work best?
M30 and H1 are currently the most consistent. Recommended pairs are USDJPY, EURUSD, GBPUSD. Gold (XAUUSD) and indices are high-volatility assets—always demo-test first.
Q7: Can I run multiple EAs or pairs on the same account?
Yes. Use a unique MagicNumber per chart and monitor margin levels.
Q8: Which AI model should I select?
o3 and GPT-4.1 provide the best cost/quality balance. o1-mini and o4-mini remain available.
Q9: How does the EA use OpenAI?
Right before entry, recent market data are sent to the model. The EA places an order only when the AI decision (BUY / SELL / NO) matches the EA’s internal filters.
Q10: Is the default configuration safe to run?
Always forward-test on a demo account first, then fine-tune RiskPercent , SpreadThresholdPip , etc. for your broker.
Q11: Any broker recommendations?
Brokers with tight spreads and fast execution such as XM, IC Markets, OANDA. Check local rules—some domestic brokers restrict automated trading.
Q12: How do I obtain an OpenAI API key?
Create an account at platform.openai.com and generate a secret key. API billing is separate from ChatGPT Plus.
■ Errors & Troubleshooting
Q: Why am I seeing "-1" every time?
- 1) WebRequest permissions are not set or the URL is wrong.
Go to Tools → Options → Expert Advisors in MT5 and make sure
https://api.openai.com is listed exactly (no typos, no spaces). - 2) API key is missing, wrong, or not verified.
Double-check your OpenAI API key in the EA input.
Confirm your OpenAI account shows a Verified badge in the Organization settings.
Correct these two settings first, then restart MT5 and try again.
Q13: “Fail to send ChatGPT request: 1 / 401 / 404 / 429”
- Check for typos or extra spaces in your API key.
- Dashboard → Settings → Organization → Verify must show Verified.
- OpenAI Billing & Usage: ensure you have credit and your usage limit isn’t exceeded.
- In MT5: Tools → Options → Expert Advisors → add https://api.openai.com to the WebRequest whitelist.
- Confirm port 443 isn’t blocked by your VPS or corporate firewall.
| Code | Typical Cause | Solution |
|---|---|---|
| -1 | WebRequest permission missing, wrong API URL, or API key not set/invalid | Add exact URL to WebRequest whitelist, double-check API key, verify account |
| 401 / 404 | Wrong API key, unverified organization, WebRequest missing | Follow steps 1-4 above |
| 429 | No credit or usage cap reached | Add funds / raise limits |
| 133 | Wrong symbol (e.g., EURUSD vs EURUSD.pro) or no trade permission | Select the correct symbol in Market Watch |
| reason = 3 / 5 | EA re-initialization notice | Informational—ignore |
Q: Why am I getting "Fail to send ChatGPT request: 404"?
Since April 2025, when using protected models like o4-mini-2025-04-16 or gpt-4.1-2025-04-14, all requests will return 404 if OpenAI organization verification is incomplete.
Resolution Steps
- Log in to https://platform.openai.com
- Navigate to https://platform.openai.com/settings/organization/general
- Click Verify Organization and complete identity verification (ID + phone number)
- Once you see the green "Organization Verified" badge, restart MT5 and reload EA
- After verification, 404 errors will resolve and protected models become available.
■ Back-testing
Q14: Can I back-test the AI logic in Strategy Tester?
No. The tester cannot call external APIs. Always validate on a demo or small live account.
■ Risk Management & New Features (v4.1+)
Q15: Does the EA control max drawdown or losing streaks?
Yes—built-in daily DD limits, partial closes, trailing stops, and loss streak counters. Enable or disable them via inputs.
Q16: Why do I see “NO SIGNAL” or no trades?
A trade is placed only when the AI and all internal filters agree. Risk-control rules can also pause trading—this is expected.
■ Set-files & Updates
Q17: Where can I download the latest recommended set-files?
Always use the newest zip published in this MQL5 blog post.
■ Other Common Questions (Q18 – Q22)
Q18: How many activations do I get per licence?
One activation per hardware ID. You can use the remaining slots on additional PCs or VPS instances.
Q19: Does the EA stop automatically on weekends and holidays?
It pauses if no new bars are generated or if the Holiday Filter blocks trading. For crypto trading on weekends, consider disabling the EA.
Q20: Does the EA use martingale or grid strategies?
No. Every trade has an individual fixed SL/TP.
Q21: Is partial close supported?
Yes—available in v4.1 and newer set-files. Earlier versions require an external script.
Q22: How many trades do I need for meaningful statistics?
Aim for 30–50 trades per pair & timeframe.
