Does Topstep Allow Automated Trading? The Rule at Each Stage
Yes on the Trading Combine and Express Funded Account, not on the Live Funded Account, where Topstep says the API isn't available. The rule at each stage quoted from Topstep, the call-up fuse that connects them, and the VPS and hedging rules every bot runs under.
Yes on the Combine and the Express Funded Account. Not on the Live Funded Account. Here's the rule at each stage, quoted from Topstep, and the catch that connects them.
Short answer: Topstep allows automated trading on the Trading Combine and the Express Funded Account, through the ProjectX API, from your own computer. On the Live Funded Account it isn't possible: Topstep says the API "isn't available on Live." So automation is allowed right up until the strategy works well enough to get you called up.
The rule at each stage
Straight from Topstep's help center:
| Stage | Simulated? | Automation | What Topstep says |
|---|---|---|---|
| Trading Combine | Yes | ✅ Allowed | "Yes, with conditions. Topstep won't help set up or troubleshoot automated strategies, and no exceptions are made for errant trades or malfunctions." (source) |
| Express Funded (XFA) | Yes, but pays real money | ✅ Allowed | "Yes, with conditions. Topstep won't help set them up or cover malfunctions." (source) |
| Live Funded (LFA) | No | ❌ Not possible | "The API Gateway is built for the simulated environment and isn't available on Live, so automated strategies are not possible at this time in the Live Funded Account." (source) |
Topstep's API page is just as direct about bots in general: "Custom automated strategies and bots are allowed via the TopstepX / ProjectX API, subject to standard platform rules and our prohibition on highfrequency trading (HFT)."
The catch: the call-up is a fuse
The Express Funded Account is simulated, but it pays real money. It's also not somewhere you get to stay.
From the Live Funded Account page:
"When the call-up comes, all Express Funded Accounts (XFA) close."
"Can I decline the invitation to move to Live and stay in my XFA? No. Once the Risk Team determines you're ready, your options are to move to Live or close your Express Funded Account."
Follow the chain. You automate an XFA, which is allowed. It works. The Risk Team notices and calls you up. Your XFAs close, you're on a Live account, and the API isn't available there.
The permission ends at exactly the point the strategy starts working. That's not a ban, it's a fuse. Know it's there before you build an income plan on an automated XFA.
Three rules that apply to every bot
1. Your own machine only. "All trading activity must originate from your personal device. The use of VPS, VPNs, and remote servers is prohibited by Topstep's Terms of Use. Running automation on a VPS can result in account suspension or removal from the program." A server can log, backtest and show a read-only dashboard. It cannot place, modify, cancel or relay an order. Any bot service that runs your orders from its cloud is putting your account on the line.
2. No hedging across accounts, even by accident. "Cross-account hedging is prohibited at Topstep." That covers holding opposite positions in the same or correlated markets (MES/ES, MNQ/NQ) across accounts, and "opposing positions are prohibited even if the overlap is brief or unintentional." Topstep is explicit that bots don't excuse it: "you're still fully responsible for all activity across your accounts, including anything created by automated systems or third-party tools." (source)
3. Every account rule still applies. "A rule violation is treated the same whether it originates from manual trading or third-party automation." Daily loss limit, maximum position size, consistency target (on the Combine, keep your best day below 55% of the profit target): the bot is held to all of it. And API orders "are final — no review, adjustment, or reversal."
"Allowed" isn't the same as "safe"
Allowed is the easy question. The two that decide whether automating helps you are these.
Does your bot enforce the rules itself? A bot can break a rule faster and more often than you ever could by hand. A logic error you'd catch after one bad trade, a script will repeat forty times before you look up. So the compliance work is building the rules into the bot:
- A daily-loss kill switch that stops the system before Topstep's limit, not at it.
- Position caps that make an over-sizing bug impossible, not just unlikely.
- A check that no two accounts can ever end up on opposite sides.
Is the strategy worth automating? Automation is an amplifier. It applies whatever you give it, exactly as written, without hesitating. A validated edge gets consistency. A hunch dressed up as a backtest gets a faster way to lose a funded account. On this desk, automation is the last step: a strategy has to survive honest fills, out-of-sample testing and the checks that separate an edge from an overfit curve before it earns a bot.
What about a trade copier?
A copier that mirrors your own clicks is a different thing from a bot that makes decisions. TopstepX has a built-in one for the Combine and XFA. Topstep copy trading covers it. If you want to trade a Topstep account from Sierra Chart, the free Sierra Chart mirror copies your clicks, and that post covers the open question of how a manual mirror is treated on a Live account.
