ATAS trade copier
Keep your footprint and order-flow charts in ATAS. With a prop firm account on Rithmic, Replica connects to the same Rithmic account and copies the trades you place in ATAS to every follower account in your group.
| What you keep | ATAS for charts and order entry |
|---|---|
| What Replica connects to | The Rithmic account behind it (username, password and System name) |
| Roles | Leader or follower |
| Followers on | Rithmic, Tradovate (NinjaTrader included) or ProjectX / TopstepX |
| Runs on | Windows 10 or 11 (64-bit) app today, which must be open while you trade. Mac, phone and cloud versions are coming soon. |
| Price | Essentials: $50 a month, $135 every 3 months or $480 a year (USD), 3-day free trial, no per-account fees. Sign-ups are opening soon. |
Supported
- Leader and follower. Trade the leader from ATAS, and the fills are copied to every follower in the group, on Rithmic or on another supported connection. A follower account open in ATAS shows Replica’s copied orders and positions like any other.
- Every order type that fills. Market, limit and stop orders, ATAS brackets included: what fills on the leader is copied, entries, exits, partial exits, scale-ins and reversals.
- Take-profit and stop-loss on followers. When the leader’s position carries both, a Rithmic follower holds them as one native OCO pair at Rithmic; other followers follow the rules of their own connection.
- Each follower at its own size. A multiplier from ×0.1 to ×5, or the leader’s contract, its Micro or its Mini, with optional Max Minis and Max Micros caps.
- Per-account risk rules. Daily Loss, Daily Profit and Trades Limit per account, with optional Enforce, plus Flatten and Flatten All from Replica.
Not supported
- Two sessions on a login that allows one. A Rithmic login has a limit on how many sessions can be open at once. If yours allows one, ATAS and Replica on the same login push each other out; ask your firm how many sessions your login allows.
- ATAS connections other than Rithmic. Replica copies Tradovate, Rithmic and ProjectX / TopstepX accounts only.
- A ATAS plugin, add-on or indicator. Replica connects to the broker account, not to ATAS, and installs nothing inside it.
- Charts or quotes inside Replica. Keep ATAS for charts and order entry; Replica shows accounts, positions, P&L and copy status.
- Copying working orders. A limit or stop entry that has not filled on the leader is not placed on followers; it is copied when it fills.
- MetaTrader 4 or 5, forex, crypto or stocks. Replica is for futures only.
- Mac, phone and cloud versions. Not yet: they are coming soon. Today Replica runs on Windows and copies only while the app is open.
- TradingView alerts or webhooks as a leader. Replica copies trades that fill on the leader account, not alerts.
How to set it up
- Install Replica on the Windows PC you trade from and sign in.
- Sign your Rithmic market-data agreements once on your firm’s own platform, if you have not already.
- In Replica, open Connections, choose Rithmic, and enter the same Rithmic username, password and System name you use in ATAS.
- In Cockpit, create a copy group: the account you trade in ATAS as the leader, your followers, and a multiplier for each.
- On the Risk page, set a daily loss limit on every follower, inside your firm’s own limit.
- Test with one micro contract placed from ATAS, then trade as you normally do.
