TopstepX to Rithmic trade copier
CopyFlock copies futures trades from a TopstepX lead account to Rithmic follower accounts in real time. Every entry, exit, stop and target that fills on the lead is sent to each Rithmic follower with the sizing, symbol and protection rules you set for it.
Each account connects to CopyFlock on its own, so the lead and followers do not need to share a platform, a firm or a computer. Copying runs on our servers — no VPS, no platform add-on and no PC left running.
- TopstepX lead — TopstepX username and a ProjectX API key
- Rithmic followers — Username, password and system
- Sizing, caps and protection per follower
- Runs in the cloud, no VPS

How copying from TopstepX to Rithmic works
If Topstep is where you trade best, you can let your TopstepX account lead Apex, TheTradingPit or Earn2Trade accounts on Rithmic. You place trades on TopstepX only, and each Rithmic account follows at its own size.
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 Rithmic followers
Rithmic followers connect with username, password and system — Apex, Bulenox, Earn2Trade, TheTradingPit, Tradeify, Rithmic 01 or Rithmic Paper Trading. Followers under one Rithmic login share a single connection, and if the firm resets the password you update it in CopyFlock.

How to copy trades from TopstepX to Rithmic
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 Rithmic follower. A card is required; cancel during the trial and you pay nothing.
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.
Step 3: Connect the Rithmic followers
Choose Add account → Rithmic and enter the username, password and system for each Rithmic login that holds a follower account.
Step 4: Create the copy
Pick the TopstepX account as the lead and the Rithmic 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.
Step 5: Add caps and protection
Set a maximum contract cap and balance or equity thresholds that fit each Rithmic account's rules. Reaching a threshold flattens and pauses that follower.
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.
Sizing example: TopstepX lead, Rithmic followers
- Apex 50K on Rithmic — equity ratio
- 50 ÷ 150 × 3 = 1 NQ
- Apex 100K on Rithmic — equity ratio × multiplier 1.5
- 100 ÷ 150 × 3 × 1.5 = 3 NQ
- TheTradingPit on Rithmic — alias NQ→MNQ ×4
- 3 × 4 = 12 MNQ
Equity ratio × multiplier scales by account size and then adjusts the result — useful when one follower should run hotter or cooler than its size alone suggests.
Things to know before copying TopstepX to Rithmic
- 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 Rithmic 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.
Frequently asked questions

Can I copy trades from TopstepX to Rithmic in real time?
Yes. CopyFlock sends each Rithmic follower its order as soon as the TopstepX lead's fill is reported. Followers fill a moment later than the lead and may get a slightly different price.
Does TopstepX need to stay open for trades to copy?
No. CopyFlock reads the lead through the ProjectX API from the cloud. Open TopstepX only when you want to place trades on the lead.
Do Rithmic followers need R|Trader Pro open?
No. CopyFlock connects to Rithmic itself, so followers fill whether or not R|Trader Pro is open. You can keep it open on the same login if you like to watch the accounts.
Can I copy from Rithmic to TopstepX as well?
Yes. Copying works in any direction between Tradovate, NinjaTrader accounts, Rithmic and TopstepX. See the Rithmic to TopstepX trade copier page.

The lead and each follower count as one account. Plans are $29/month for up to 10 accounts, $49/month for up to 20, or $99/month for unlimited accounts, with every feature on every plan. The ProjectX API subscription for TopstepX is billed separately by ProjectX. See pricing.
