Both are popular, both have an API — but for a bot, they pull in opposite directions: FundedNext leans automation-permissive (and on its own), Topstep leans structured-but-restricted. Here's the head-to-head on what matters for an algo.
Independent tooling — not affiliated with either firm, no affiliate links. Confirm on each firm's official page (linked) before you buy.
| For a bot… | FundedNext Futures | Topstep |
|---|---|---|
| Bots / EAs | Allowed — but no setup support | Allowed, actively-monitored only |
| Broker API | Verify the current path | Yes (ProjectX, no sandbox, orders final) |
| VPS / remote 24-7 | Not confirmed — verify | Prohibited |
| Live-account automation | Not confirmed — verify | Restricted (LFA) |
| Latency / HFT | No latency-exploit / order-flooding | No HFT |
| Drawdown engine | Trailing | Trailing → locks at start |
| Serbia eligibility | Appears open (verify) | Express-only (XFA), no live API |
| Hand-holding | None for bot/EA setup | Structured program, brand trust |
you want a more automation-permissive home, you're outside the US / in a Topstep-restricted country (e.g. Serbia), and you're comfortable setting the bot up yourself with no support.
you want a structured, well-known program and you'll actively monitor a bracketed bot on your own machine — and you don't need a VPS or unattended live-account automation.
Bottom line for hands-off automation: FundedNext is the more permissive fit; Topstep is the wrong tool if your plan is a 24/7 unattended bot. Either way, the drawdown engine — not the brand — is what ends accounts.
AlgoProven models both firms' exact rule-sets — drawdown, daily loss, consistency, automation policy — and checks every trade before your bot sends it. Free on the simulator.
