TopstepX to NinjaTrader trade copier

How copying from TopstepX to NinjaTrader works

You trade Topstep on TopstepX and also hold accounts you usually run in NinjaTrader 8 — a NinjaTrader brokerage account or prop accounts at Apex or My Funded Futures. With TopstepX leading, those accounts follow without NT8 having to stay open.

The TopstepX lead

The TopstepX lead connects through the ProjectX API with your TopstepX username and an API key. You keep trading in TopstepX as usual; CopyFlock reads the lead's fills through the API, so that login needs an active ProjectX API subscription.

The NinjaTrader followers

Follower orders land on the account behind NinjaTrader, so NT8 shows the copied position like any other order on that account. NinjaTrader does not have to be running for followers to fill, and no ATM strategy manages a copied position — turn on copy TP/SL so followers carry their own stop and target.

What you need on each side

How to copy trades from TopstepX to NinjaTrader

1. 1

   Step 1: Start a free trial

   Create a CopyFlock account and start the 7-day free trial on 2 accounts — one TopstepX lead and one NinjaTrader follower. A card is required; cancel during the trial and you pay nothing.

2. 2

   Step 2: Connect the TopstepX lead

   Activate ProjectX API access for your TopstepX login and generate an API key, then choose Add account → TopstepX and enter your TopstepX username and the key.

3. 3

   Step 3: Connect the NinjaTrader followers

   Add each account you trade in NT8 by the connection behind it: Tradovate for NinjaTrader brokerage and Tradovate prop accounts, Rithmic for prop accounts on a Rithmic login.

4. 4

   Step 4: Create the copy

   Pick the TopstepX account as the lead and the NinjaTrader accounts as followers. Choose a sizing mode for each follower: contract multiplier 1 for the same size, equity ratio for accounts of different sizes, or fixed contracts.

5. 5

   Step 5: Add caps and protection

   Set a maximum contract cap and balance or equity thresholds that fit each NinjaTrader account's rules. Reaching a threshold flattens and pauses that follower.

6. 6

   Step 6: Test with one contract

   Place a one-contract trade on the TopstepX lead and confirm each follower's order in the copy log. During the trial, followers copy a fixed 1 contract.

Things to know before copying TopstepX to NinjaTrader

• Followers fill after the lead. Each follower order is sent once the lead's fill is reported, so follower prices can differ slightly, especially with market orders in fast markets.
• Manual changes stay manual. If you close a follower by hand, it stays closed and joins in again with the lead's next trade.
• Symbols copy as they are. A NinjaTrader follower trades the lead's contract unless you add a symbol alias, for example NQ to MNQ.
• Futures only. CQG, Quantower and Volumetrica connections are not supported.
• Prop firm rules come first. Check that every firm involved allows copying between your own accounts — see prop firm copy trading rules.
