Many prop firms say they allow Expert Advisors, but the details decide whether your robot is actually usable. A normal execution EA, an MQL5 strategy, a copier, a grid/martingale bot and a latency arbitrage system are treated very differently.
These keywords share the same search intent, so they are combined into this single canonical page to avoid duplicate SEO pages.
Most EA-friendly firms still prohibit strategies that exploit platform delays, stale quotes, tick scalping, latency arbitrage, reverse arbitrage or abusive account cycling. Some also restrict martingale, grid systems without stop loss and third-party managed bots.
MetaTrader support matters because many EAs are built in MQL4 or MQL5. If a firm moves to DXTrade, cTrader or TradingView, the same EA may not run natively. Always confirm the platform for both evaluation and funded stages.
Send a short description of the strategy, holding time, average trades per day, copier use, max risk per trade and whether the EA is commercially sold. Save the written answer with the rulebook date.
This page is written to match the exact search intent without stuffing keywords. Prop firm rules change often, so always confirm the live rulebook, payout policy and legal entity before paying for an account.
Yes, but only if the strategy is robust and compliant with the firm rules. Passing with overfit settings or excessive risk usually fails later at payout review.
Some MT5 firms do, but availability varies. Confirm whether EAs are allowed by default or require an add-on.
Usually no if HFT means latency exploitation or abusive tick scalping. Some firms use the phrase loosely, so read the specific prohibited-strategy list.
