What is ProjectX?
ProjectX is a white-label futures trading platform and API. Rather than building trading infrastructure from scratch, a prop firm runs on ProjectX and presents it under its own brand. TopstepX is Topstep's platform built on ProjectX — which is why Topstep's own documentation describes its API access as powered by ProjectX and billed separately.
Topstep is the most visible ProjectX firm, but it is not the only one. Each firm gets its own API endpoint while sharing the same API structure underneath. That is the detail that matters for trade copying: a copier that integrates ProjectX properly can serve several firms, not just one.
SyncMyTrade treats the prop firm as a field on the connection rather than something hard-coded. You pick your firm from a list when you add the connection, and you can hold connections to several firms at once.
ProjectX and Topstep,
as things stand now.
A futures trading platform and API layer. A prop firm runs on ProjectX and presents it under its own brand rather than building trading infrastructure itself.
TopstepX is Topstep's platform, built on ProjectX. Topstep's own documentation describes TopstepX API access as powered by ProjectX and billed separately from the Topstep subscription.
ProjectX wound down its third-party platform offering for partner firms through 28 February 2026, and projectx.com now points to Topstep. In practice, connecting via ProjectX today means connecting a TopstepX account.
Firms that moved off ProjectX have generally migrated to Rithmic or Tradovate. SyncMyTrade supports both, so a copy setup can be rebuilt on the new platform.

From API key to copied trade
in three steps.
Generate an API Key
In the TopstepX dashboard, open Settings → API and create a key. API access is billed separately from your Topstep subscription and is managed through the ProjectX dashboard.
Add the Connection
In SyncMyTrade, create a new connection, choose ProjectX as the broker and TopstepX as the prop firm, then enter your username and API key. Every account on the login is imported automatically.
Build Your Copy Group
Choose a leader account, add followers, set a copy ratio for each, and start trading. Orders on the leader replicate to every active follower.
Step-by-step with screenshots in the brokers & connections guide.
Built for how ProjectX
accounts actually work.
Several TopstepX Accounts, One Connection
A single ProjectX connection imports every account on your TopstepX login — evaluation and funded alike. Each one can act as leader or follower with its own settings, so you are not adding a connection per account.
API Key Setup, No OAuth Dance
ProjectX authenticates with a username and API key rather than OAuth. Generate a key in your TopstepX dashboard, paste it in once, and SyncMyTrade handles token refresh from there. Note that API access is a separate subscription from your Topstep account.
Mix ProjectX With Other Brokers
A TopstepX account can lead a group of Tradovate followers, or follow a Rithmic leader. Contract specifications are mapped across platforms so a trade on one broker lands correctly on another — useful if you trade Topstep alongside firms on other platforms.
Session Lock
Halt everything on demand. Session Lock stops copying across the group, cancels working orders and flattens open positions — a self-imposed trading halt for when you need to stop.
Leader–Follower Integrity Checks
Automatic leader–follower integrity checks compare each TopstepX account against your leader and act when a mismatch is detected. If an account breaches, it is deactivated rather than left copying.
Nothing to Keep Running
The copy engine runs in the cloud. No VPS to rent, no desktop application that has to stay open, and no local machine that has to survive the trading session.
