Export MT4 / MT5 bots

From a strategy detail or portfolio page you can export a MetaTrader Expert Advisor (EA).

​
Plan requirements

See quotas under Plans and billing. Only successful downloads count.

​
Individual strategy

  1. Open the strategy in the Databank.
  2. Export bot → choose MT4 or MT5.
  3. Review the block coverage report.
  4. Download the .mq4 / .mq5.
Export EA MQL4/MQL5

Export to bot dialog. Click to zoom.

The EA exposes execution parameters as inputs (sizing, ATR SL/TP/trail, magic, session, GMT offset, etc.) so you can calibrate in the terminal without rewriting logic.

​
Portfolio

From strategy detail you download a bot for that single strategy. From a portfolio you download the set of strategies added to that portfolio (the mix you backtest together). Broker aliases are set under Settings → Instruments (or in the export dialog). See Broker symbol names.

​
Broker symbol names

Quanorix uses canonical names (e.g. NAS100, XAUUSD). Your broker may show a different Market Watch ticker (USTECH, USTEC, NASUSD, …). How that affects the bot:

​
Several strategies on the same asset

That is normal portfolio packaging, not a bug. Distinct magics isolate orders in the terminal. Operational caveat (not an export bug): more exposure if they open together; on MT5 netting accounts the broker nets the symbol into one position (no independent long+short); hedging allows multiple.

​
Nasdaq example

  1. Portfolio with 2–3 strategies on NAS100.
  2. Export MT4, open the USTECH chart (or your broker’s Nasdaq), attach that symbol’s .mq4 → it trades that chart.
  3. Export MT5 with no alias → the bot looks for NAS100. If Market Watch only has USTECH, set alias NAS100 → USTECH and re-export.
If you use the MCP assistant to export a portfolio, confirm the broker name map (or say that on MT4 you will attach to the right chart) before generating.

​
Block coverage

  • Supported blocks: exportable with expected parity.
  • Blocking unsupported blocks: UI/API prevents generating an incomplete EA by default.
  • Some blocks may export with an approximate warning — read the reason before live trading.
After major parity/TZ changes, re-export older EAs.

​
Inputs you should know

​
Realistic expectations

  • MT4 pending lists can show more states than the app (the app lists executed fills).
  • Excel reports use raw UTC; HTML uses display_tz.
  • Parity depends on aligned history, GMT offset, and costs (spread/commission).

​
Pre-live checklist

  1. Same history/TZ mental model as the backtest (or calibrated offset).
  2. Coverage without surprises.
  3. Correct broker aliases when needed (especially MT5 portfolio).
  4. Test in Strategy Tester with the same InpBrokerGmtOffset you will use live (or document the difference).
