Rithmic to TopstepX trade copier
CopyFlock copies futures trades from a Rithmic lead account to TopstepX follower accounts in real time. Every entry, exit, stop and target that fills on the lead is sent to each TopstepX 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.
- Rithmic lead — Username, password and system
- TopstepX followers — TopstepX username and a ProjectX API key
- Sizing, caps and protection per follower
- Runs in the cloud, no VPS

How copying from Rithmic to TopstepX works
Many futures traders hold Rithmic evaluations at Apex or Bulenox alongside Topstep accounts. With the Rithmic account leading, every trade you place in R|Trader Pro or NT8 is copied to your Topstep accounts on TopstepX.
The Rithmic lead
The Rithmic lead connects with the username, password and system your firm gives you. Trade it from R|Trader Pro, NinjaTrader 8 on a Rithmic connection or any other Rithmic front end; R|Trader Pro can stay open on the same login while CopyFlock is connected.
The TopstepX followers
TopstepX followers connect through the ProjectX API as well. API access is a separate ProjectX subscription for the TopstepX login — CopyFlock cannot place orders on TopstepX without it — and Topstep's own rules on copy trading and position limits apply to every Topstep account.

How to copy trades from Rithmic to TopstepX
Step 1: Start a free trial
Create a CopyFlock account and start the 7-day free trial on 2 accounts — one Rithmic lead and one TopstepX follower. A card is required; cancel during the trial and you pay nothing.
Step 2: Connect the Rithmic lead
Choose Add account → Rithmic, enter the Rithmic username and password and pick the system your firm uses — the same details you enter in R|Trader Pro.
Step 3: Connect the TopstepX followers
Activate ProjectX API access for the TopstepX login that holds the followers, then choose Add account → TopstepX and enter the username and API key.
Step 4: Create the copy
Pick the Rithmic account as the lead and the TopstepX 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 TopstepX account's rules. Reaching a threshold flattens and pauses that follower.
Step 6: Test with one contract
Place a one-contract trade on the Rithmic lead and confirm each follower's order in the copy log. During the trial, followers copy a fixed 1 contract.
Sizing example: Rithmic lead, TopstepX followers
- Topstep 50K — fixed risk 0.6%
- 0.6% × $50,000 = $300 ÷ $300 = 1 ES
- Topstep 150K — fixed risk 0.6%
- 0.6% × $150,000 = $900 ÷ $300 = 3 ES
- Topstep 50K — alias ES→MES ×5
- 2 × 5 = 10 MES
Fixed risk % works from each follower's own equity, so a follower risks less after a losing day and more after a winning one.
Things to know before copying Rithmic to TopstepX
- 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 TopstepX 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
Still have questions? Read the full FAQ or email support.
Can I copy trades from Rithmic to TopstepX in real time?
Yes. CopyFlock sends each TopstepX follower its order as soon as the Rithmic lead's fill is reported. Followers fill a moment later than the lead and may get a slightly different price.
Does Rithmic need to stay open for trades to copy?
No. CopyFlock connects to Rithmic directly from the cloud. Keep R|Trader Pro or NT8 open only when you want to trade the lead from it.
Can I trade the Rithmic lead in NinjaTrader and copy to TopstepX?
Yes. NT8 on a Rithmic connection places orders on the Rithmic account, and CopyFlock copies them to the TopstepX followers when they fill. See the NinjaTrader to TopstepX page.
Can I copy from TopstepX to Rithmic as well?
Yes. Copying works in any direction between Tradovate, NinjaTrader accounts, Rithmic and TopstepX. See the TopstepX to Rithmic trade copier page.
How much does copying Rithmic to TopstepX cost?
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.
