Can you use trading bots with prop firms?
Short answer: yes, most prop firms allow bots. The rule that ends automated accounts is almost never the bot policy.
Most firms permit automated trading. What kills funded accounts is the drawdown rules — daily loss and trailing max drawdown, both usually measured on floating equity. Open positions can breach a limit before a single trade closes.
What's allowed, what's banned
FTMO, FXIFY and the other big evaluation firms permit Expert Advisors on both evaluation and funded accounts. (FXIFY is an official Velox partner: code VELOX takes 10% off every program; affiliate partnership, Velox earns a commission. Details on the brokers page.) What they ban is a narrower set of techniques:
| Usually fine | Usually banned |
|---|---|
| A bot trading its own signals on one account | Latency / tick-scalping arbitrage against the firm's feed |
| Holding positions for hours or days | High-frequency strategies (minimum-hold-time rules) |
| Automated risk management (SL/TP, breakeven) | Copy-trading identical signals across many accounts |
Rules differ by programme and change often — read your firm's prohibited strategies, minimum hold time and consistency rule sections; that's where the surprises live.
The two rules that end accounts
| Rule | What it means | Why bots trip it |
|---|---|---|
| Daily loss limit | Cap on one day's loss, from that day's starting equity. | Several open positions on correlated pairs move together. |
| Trailing max drawdown | A floor that follows your peak equity up — and rarely comes back down. | Every winning streak narrows your own room for a normal losing one. |
Both are usually measured on equity, not closed balance — floating losses count. Four positions with a 1% stop each are not risking 1%; in a news spike that hits every correlated dollar pair at once, they're risking ~4% simultaneously. No software can un-open a position once the risk is on the books.
The protective question isn't "what do I risk per trade?" It's "if everything open hit its stop in the same minute, would I breach the daily limit?"
How many positions is too many
Fewer than most traders assume. Two positions at up to 1% risk each keep the absolute worst case inside a typical 3–5% daily limit with margin to spare; five or six correlated pairs don't. This is pure arithmetic about the worst case, not market prediction — and it's why a bot that seems to "trade too little" may simply intend to still exist next month.
One-phase vs two-phase
Compare drawdown structures before profit targets. One-phase programmes often pair a fast target with a tight trailing drawdown — a corridor that keeps narrowing. Two-phase usually allows more time and a more forgiving structure, which suits a system that trades steadily. In our own historical rule-set simulations (limits fully disclosed on the research page), the drawdown rule decided survival far more often than the profit target did.
Checklist before you start
Read the prohibited-strategies section — and screenshot it
Rules change; disputes are resolved against what was published.
Balance or equity?
If limits are measured on equity (usually), floating losses count.
Calculate your worst-case day
Every open position stopped at once — does it fit inside the daily limit?
Check what the trailing drawdown follows
Peak-equity trailing is harsher: an unrealised spike you never banked still raises the floor.
Demo first
Evaluation fees aren't refunded when a bot behaves differently than assumed.
What we can't tell you
Nobody can tell you a bot will pass an evaluation — ours included. What's knowable is mechanical: whether worst-case exposure fits the limits, whether it holds through news, whether it stops at the daily line. Those properties decide if the account survives long enough for any edge to matter — and you can verify them before risking a fee.
How Velox handles this
Hard-coded risk caps the AI cannot override, a two-position ceiling, a daily-loss circuit breaker that counts floating losses, and a prop-firm mode that guards the firm's lines before they can be breached.
