Quick answers
The questions traders bring to us most, answered in a line or two.
What is Replica?
Replica is a Windows desktop trade copier for futures traders. You trade one leader account and Replica copies every fill to any number of follower accounts, each at its own size.
Which brokers and platforms does Replica support?
Tradovate, NinjaTrader, Rithmic and TopstepX (ProjectX). Because Replica copies fills on the broker account, you can place the leader’s trades from any platform connected to it, such as TradingView, Quantower, Sierra Chart or Tradesea.
How many accounts can I copy to?
There is no limit. One leader per copy group, any number of followers, any number of groups and connections.
Does Replica work with prop firm accounts?
Yes. Most prop firm futures accounts run on Tradovate, Rithmic or TopstepX. Check that your firm allows copy trading between your own accounts before you start.
Do I need to keep my PC on?
Yes. Replica runs on your own PC, and copying and risk rules only run while the app is open. Take-profit and stop-loss orders already placed at the broker stay in place if it closes.
Can a follower trade micros when the leader trades minis?
Yes. Each follower can trade the leader’s contract, its Micro or its Mini, with an optional Max Minis or Max Micros cap.
Does Replica have daily loss limits per account?
Yes. Daily loss, daily profit, trades per day, a contract cap and a symbol lockout, per account. With Enforce on, a breached daily limit closes the account and locks it until the 17:00 Chicago reset.
How much does Replica cost?
Essentials is $50 a month, $135 every 3 months or $480 a year, with a 3-day free trial and no per-account fees. Sign-ups are opening soon.
