TopstepX / ProjectX API connects through ProjectX endpoints where account API access is available, not screen scraping

Internal dispatch is measured separately from provider acknowledgement and fills

Connection availability follows the exact account route and provider permissions

Encrypted credentials or tokens with an audit record for routed signals

Connection availability: A platform or prop-firm name does not by itself guarantee API access. The exact account must use a supported route and provide the account, event, position, and order permissions required for its role. Validate the full entry and exit workflow before using live or funded capital.

How the TopstepX / ProjectX API route works

COPIERA connects through ProjectX endpoints where account API access is available. TopstepX / ProjectX API can participate as a leader or follower when the account route exposes the required event, account, position, and order permissions. The route must be validated for the exact account before it is used with live or funded capital.

Use TopstepX / ProjectX API inside a defined copy group

A copy group has one leader and selected followers within the subscription plan. An eligible TopstepX / ProjectX API account can be used in that structure when its provider returns the account and grants the operations COPIERA needs.

Per-follower controls

Each follower has a whole-number ratio, micros-only control, and maximum-position cap. These settings are evaluated before an eligible opening request is sent, so accounts in one group can retain different sizing constraints.

Risk and journal included

Daily and weekly loss limits, profit goals, and trailing drawdowns are enforced by the engine itself — not by a UI button. Every copied trade is also logged with entry, exit, side, qty, and P&L for the journal so you can audit TopstepX / ProjectX API performance over any time range.

TopstepX / ProjectX API Trade Copier — questions answered

How does COPIERA connect to TopstepX / ProjectX API?+
COPIERA uses ProjectX endpoints where account API access is available. TopstepX / ProjectX API can participate as a leader or follower when the account route exposes the required event, account, position, and order permissions. Exact availability depends on the account provider and its current permissions.
Will the TopstepX / ProjectX API copier work while my computer is off?+
The copy engine runs in the cloud and does not require a trader-managed VPS. It remains dependent on COPIERA service availability, valid provider sessions, credentials, permissions, and the broker route itself.
Can I scale a TopstepX / ProjectX API leader to a different size on followers?+
Yes. Each follower account has an independent multiplier and rounding policy, plus an optional micro-contract substitution. You can copy 1 ES from a leader as 5 MES on a small follower or 3 ES on a larger follower.
What happens if my TopstepX / ProjectX API session disconnects?+
COPIERA reports the connection state and records routing outcomes. Supported routes use token refresh, reconnect, or backoff behavior appropriate to the provider. If authorization cannot be restored, the user is told to reconnect instead of the UI presenting the account as healthy.
Can I use TopstepX / ProjectX API alongside TradingView alerts?+
Yes. A leader can publish trades through TopstepX / ProjectX API's native stream or through TradingView webhooks. Followers receive one normalized futures signal and act on it.
Is there a TopstepX / ProjectX API trial?+
Every paid plan starts with a 7-day trial. Add TopstepX / ProjectX API as a follower (or leader) inside the trial and verify execution speed against your own playbook before committing.
