Free NinjaTrader 8 Trade Copier — Mirror Orders Across Multiple Accounts (NinjaScript Indicator)

I’ve been running multiple NinjaTrader 8 accounts for a while and got tired of manually duplicating trades across tabs. Couldn’t find a good free in-platform solution, so I built one.

I traded 4 accounts, so initially I built it for 3 followers. If you’re just getting started with multiple accounts, 1 master + 3 followers is more than enough to begin with.

Sharing it here in case anyone else has the same problem.

NexusCopier Free runs as a chart indicator inside NT8 and copies fills, stops, and targets from a master account to up to 3 follower accounts in real time. No external bridge or third-party software needed.


A few things worth knowing before you try it:

  • Per-follower quantity ratio setting (follower can trade a different size than master)
  • Supports micro/full-size pairs automatically: ES/MES, NQ/MNQ, YM/MYM, GC/MGC, BTC/MBT, and others
  • Max entry slippage filter — followers skip the copy if price has moved beyond a tick threshold by the time the order reaches them
  • Anti-hedging guard — blocks a follower from opening a position opposite to the master
  • Wrong-side stop detection — if the master’s stop is on the wrong side after a gap, you can configure the follower to emergency-flatten at market rather than hold a naked position
  • Safety cap of 30 contracts per follower submission
  • Flat check on entry so a follower already in a position doesn’t double-up
  • Live PnL per follower shown directly on the chart panel
