What you can do
Copy across ProjectX accounts with rules built in.
ProjectX is the trading technology behind a growing number of futures prop firms, including TopstepX. MimikTrader connects to ProjectX accounts through the ProjectX API, mirrors orders from a leader account to selected followers in real time, and enforces each account's risk rules on every tick.
- Connect ProjectX accounts with your platform username and API key
- Create copy groups with one leader and multiple followers
- Set follower sizing per account with a per-account multiplier
- Apply daily loss, drawdown, and profit drawdown enforcement per account
- Auto-flatten and lock breached accounts
- Record fills, orders, and breach events in the journal
How it connects
Connect ProjectX in a couple of minutes.
There's no desktop app and no OAuth redirect. Generate an API key inside your prop firm's ProjectX platform, then add the connection in MimikTrader with your prop firm, platform username, and that key. Your accounts and balances appear as soon as the connection authenticates.
- Generate an API key — In your ProjectX platform, open Settings / API and generate a new key. Click the eye icon to reveal it, then copy it in full.
- Add the connection — In MimikTrader go to Connections → Add Connection → ProjectX, choose your prop firm, and paste your platform username and API key.
- Verify — Once connected you'll see your ProjectX account balances and connection status in the Connections tab.
- Group it — Add your ProjectX accounts to a copy group as leader or followers alongside Tradovate, NinjaTrader, and Rithmic accounts.
Prop firm note
Compatible with ProjectX-routed prop firms.
Many futures prop firms route their accounts through ProjectX, including TopstepX. MimikTrader compatibility depends on whether your account routes through this broker connection — check your account routing before setting up copy trading.
Topstep Live (funded) accounts are not supported for copy trading and should not be added as leaders or followers in any copy group. MimikTrader is independent software; prop firm names are referenced for compatibility context only and do not imply affiliation or endorsement unless explicitly stated.
Risk Management
8 Pre-Trade Risk Checks on Every Account
Prop firm rules, account sizes, and policies are subject to change. Always verify current rules directly with your prop firm before configuring your risk settings.
- Daily Loss Limits — Automatic position flatten and account lock when daily loss threshold is reached.
- Trailing Drawdown — Equity high-water mark tracked on every price tick — essential for prop firm accounts.
- Profit Drawdown Protection — Cap give-back from your daily peak to protect gains.
- Auto-Flatten & Lock — Instant position closure the moment any risk rule is breached.
- Per-Account Multipliers — Size each follower up or down from the leader independently.
- Weekly Limits — Cumulative weekly loss and profit controls across multiple sessions (verify current wiring for your account).
- Max Daily Trades — Limit round-trip trades per day to stay within firm guidelines.
- Tick-Level Enforcement — Risk rules checked on every market tick, not just at trade entry.

Step 01
Trade copied across five accounts
You place a trade on the leader account. MimikTrader sends the correct order to each follower based on its copy settings.
Step 02
One account reaches its daily loss limit
Account 03 hits the configured daily loss threshold while the copied position is still live.
Step 03
MimikTrader flattens the affected account
The breached account is closed according to your configured flatten rule.
Step 04
The account is locked
New copied trades are blocked from entering that account until the lock is cleared.
Step 05
Other accounts keep running
Accounts 01, 02, 04, and 05 continue following the copy group because they did not breach their rules.
Step 06
The event is recorded
The fill, breach, flatten action, account lock, and timestamp are written to the trade record.

FAQ
ProjectX Trade Copier Questions
Yes. ProjectX is supported today. Connect each prop firm's ProjectX accounts with your platform username and an API key generated in your ProjectX platform, then copy trades across them with full risk management — all from the cloud, no desktop app required.
ProjectX is a trading platform that provides futures order routing and execution. It is used by several prop firms — including TopstepX — as their trading technology backbone, offering charting, order entry, and real-time market data. Some prop firms offer ProjectX alongside Tradovate or Rithmic routing.
In your prop firm's ProjectX platform, open Settings / API and generate an API key (click the eye icon, then copy it in full). In MimikTrader, go to Connections → Add Connection → ProjectX, select your prop firm, and enter your platform username and API key. Your accounts and balances appear once the connection authenticates.
Error code 3 means 'Unauthorized' and is almost always a credential input issue, not a MimikTrader problem. Double-check that the API key is linked to your ProjectX account, copied in full with no missing characters (paste into Notepad first to verify), and revealed with the eye icon before copying. For the username, try the username shown on your prop firm dashboard, your account email, or the username you use to log in to your ProjectX platform.
No. MimikTrader does not support copy trading on Topstep Live (funded) accounts. ProjectX Live accounts should not be added as leaders or followers in any copy group. Use evaluation / simulated ProjectX accounts for copy trading.
If you include a ProjectX account as a follower, make sure ProjectX-side Position Bracket and OCO Bracket automation is turned off on that account, as it can interfere with replication. As long as accounts don't overlap, you can also run replication on the ProjectX side and only include the ProjectX leader account in a MimikTrader group — customize the setup however you like.
Yes. You can copy across ProjectX, Tradovate, and NinjaTrader accounts in a single copy group. The leader can be on one platform and the followers on any supported platform.
No. Like our Tradovate integration, ProjectX trade copying is entirely cloud-based. No desktop application needs to be running for MimikTrader to detect and copy your trades — everything happens server-to-server.
