How to pick a prop firm a bot can live on
The first question is not how to build the bot. It is which firm will let it run. Most futures firms ban or restrict fully automated trading on the funded account, and the rules are written to catch you out, so picking the wrong firm wastes the whole build. This is the checklist I run before I put a bot on any firm, in the order that decides it.
I keep a current, ranked list of which firms allow what on the automation page. This guide is the how-to-choose behind that list, so you can read a new firm's rulebook yourself and know in five minutes whether it is worth your time.
1. Does it allow a bot on the funded account, not just the eval
This is the trap that catches the most people. A firm will happily let a bot pass the evaluation, then ban automation the moment you reach the funded account, where the real money is. Topstep is the clean example: its API automation works on the eval and the paid Express Funded account, but not on a Live Funded account. So you confirm the rule covers the exact account you will get paid on, not just the test.
Read the firm's permitted-activities page, not the sales page, and look for the word funded. If automation is eval-only, the bot is a way to pass a challenge you then cannot trade. That is a no.
2. The drawdown type
An end-of-day drawdown only measures your balance at the close, so intraday swings do not breach you. A trailing intraday drawdown follows every tick of unrealized profit and can stop you out on a pullback from a high you never banked. For a bot that takes a lot of trades, an end-of-day drawdown is far more forgiving, and a few firms now offer it on every plan.
Match the drawdown to how your strategy behaves. A scalper that gives back open profit constantly will get chopped up by an intraday trailing drawdown. The same bot on an end-of-day firm survives. This is a strategy-to-firm fit problem, not a best-firm problem.
3. How you actually connect it
There are three ways in, and they are not equal. A real developer API, like Topstep's TopstepX through ProjectX or Lucid's custom interface over Rithmic, gives you REST and WebSocket endpoints to send orders from your own code. A platform API like Tradovate, Rithmic, or NinjaTrader runs your bot through a charting platform. A bridge like TradersPost, CrossTrade, or PickMyTrade turns a TradingView alert into an order. Only two of these firms offer a genuine dev API.
Pick the connection before you fall for a firm. If you are writing custom logic and care about control and latency, insist on a dev API. If your strategy is alert-driven, a bridge is faster to set up and fine. Also check where the bot is allowed to run: Topstep, for one, requires it to run locally on your own machine, and running it on a VPS can get the account suspended.
4. The consistency rule and the payout gates
Passing the eval is not the hard part. Getting paid is. Many firms add a consistency rule, often that no single day can be more than 30 to 50 percent of your total profit, which quietly forces a bot to spread gains across days rather than bank one big session. Others gate the first payout behind a minimum number of trading days or a buffer above the starting balance. A bot has to be told about these, because it will not infer them.
Before you commit, find the consistency rule, the minimum days to a payout, and how fast payouts actually clear. A firm with a soft eval and a brutal payout gate is worse for a bot than one with a hard eval and clean payouts.
5. The real cost after resets
An automated trader buys resets. Some accounts will fail on variance alone, so the price that matters is the monthly fee after the live coupon plus the resets you will realistically buy, not the sticker price. A firm that looks cheap with a one-time activation fee and no monthly cost can end up more expensive than a monthly firm once you price the resets across several accounts.
Once you have those five answers, the choice is usually obvious. The ranked version, which firms clear all five and which to avoid, is on the automation page, and every firm review here has a Can you run a bot on this firm section with the current rule.
FAQ
What is the most important thing when picking a prop firm for a bot?
Whether the firm allows automation on the funded account, not just the evaluation. Several firms let a bot pass the eval and then ban it once you are funded, which makes the build useless. Always confirm the rule covers the account you will actually get paid on.
Which futures prop firms are best for automated trading?
It depends on your strategy and how you connect, but the firms that allow your own bots include Lucid Trading, Bulenox, and Tradeify, with Topstep offering a real developer API on the eval and Express Funded account. The automation page ranks them and lists which only allow supervised or semi-automated trading.
Do I need a developer API or is a TradingView bridge enough?
If your strategy is alert-driven, a bridge like CrossTrade or PickMyTrade is faster to set up and fine. If you are writing custom logic and care about control and latency, insist on a firm with a genuine developer API, which among futures firms is mainly Topstep and Lucid.
Why does the funded account matter more than the eval for a bot?
Because the eval is a test you pass once, while the funded account is where you trade for real and get paid, often for months. A firm that allows a bot on the eval but bans it when funded gives you a way to pass a challenge you then cannot automate.
