Topstep trade copier

Topstep’s copy trading rules

From Topstep’s own pages, checked on October 29, 2026. Firms change these rules often: open the sources and confirm before you start.

• Copying is allowed on Combines and Express Funded accounts. Topstep: “You can also use a trade copier to duplicate trades across multiple accounts.” Its own TopstepX copier works on “Trading Combine® and Express Funded Account® accounts” only.
• Not on Live Funded accounts. “Live funded accounts are not allowed to trade through the ProjectX API.”
• Third-party API tools are at your own risk. “Some traders connect third-party applications to the ProjectX API. If you do, it’s at your own risk.”
• Orders from your own device. “All trading activity must originate from your personal device.” VPS, VPNs and remote servers are prohibited.
• No hedging. “Opposing positions are prohibited even if the overlap is brief or unintentional,” and Topstep tells traders to monitor copy trading tools so they do not create opposite positions.
• Account limits. No limit on Trading Combines; “You can hold up to 5 active XFAs at a time.”

What Replica does on Topstep accounts

• Any of your Topstep accounts can lead or follow, at its own multiplier from ×0.1 to ×5, rounded up to a whole contract.
• Mix firms in one group. A leader on one firm can copy into followers at other firms and on other connections.
• Fill-driven copying. Followers are sent their orders when the leader fills, so a cancelled leader order never leaves a stray order on a follower.
• A risk limit per account. Set Daily Loss, Daily Profit and Trades Limit on every account, inside the firm’s own limits, with optional Enforce.
• One-click exits. Flatten closes one account and Flatten All closes the whole group, on the first click.
• Unlimited accounts, no per-account fees. One price however many accounts you copy into.

What to watch

• Each account keeps its own limits. Copying does not merge accounts: every account has its own drawdown, daily loss and size limit at the firm.
• Fill prices can differ. Followers enter at market after the leader fills, so in fast markets their prices can differ from the leader’s.
• One copier per account. Turn off any other copier on the accounts Replica copies into; two copiers copy every trade twice.
• Same direction only. Copying into opposite positions across accounts is hedging, and firms ban it.
• MetaTrader 4 or 5, forex, crypto or stocks. Replica is for futures only.
• Mac, phone and cloud versions. Not yet: they are coming soon. Today Replica runs on Windows and copies only while the app is open.
• TradingView alerts or webhooks as a leader. Replica copies trades that fill on the leader account, not alerts.

How to set it up

1. Get a ProjectX API key for your TopstepX login.
2. Install Replica on your own Windows PC, not a VPS, and sign in.
3. Open Connections, choose ProjectX (Topstep), and enter your TopstepX username and the API key.
4. In TopstepX, turn the Trade Copier off on every account Replica copies into.
5. Create a copy group in Cockpit with Combine or Express Funded accounts only. For take-profit and stop-loss on followers, switch on Auto OCO (see the TopstepX page).
6. Set a daily loss limit on every account on the Risk page, inside Topstep’s own limits, and test with one micro contract.
