PFX Copier.One trade. Every account.
Trade your lead account the way you always do, by hand, with an ATM or with a strategy. Every follower copies it: the entry, the stop, the target and every move you make to them, at the size you set for each one.

Every follower.Its own size.
Drag the lead's size and change each follower's rule. Sizes always round down, never up, so a follower never takes more than you meant.
Build your copier.txt.Right here.
Settings live in a small text file. Choose a mode, add your followers, and the file writes itself. Copy it into Documents\NinjaTrader 8\PFX\. It's read again every 10 seconds.
You trade.They follow.
Scroll through one trade and watch what each follower does.
You buy 2 on the lead.
Every follower enters at its own size: 2, 4 and a fixed 1. A follower that started late doesn't chase an old entry; it waits for the next trade.
Your orders, copied.
The stop and target you place go onto every follower, on the right side of the market. A limit you use to add to the trade isn't mistaken for a target.
Every move, copied.
Drag your stop to break-even and each follower's stop follows. Change the target and theirs change too.
One follower stands down.
Sim103 reaches its daily loss stop. It's flattened and sits out until tomorrow. The lead and the others carry on.
Flat together.
Close the lead and every follower closes with it. Your own trades on a follower are never touched.
It will.It will never.
- Copy entries, stop, target and every move of them
- Close followers when the lead is flat
- Pick up again after a restart or reconnect
- Stop a follower at its daily loss limit
- Touch the lead account
- Touch a follower trade it didn't open
- Put a follower on the opposite side
- Chase an old entry after a late start
One file stops everything.
Create an empty file called copier.kill in the PFX folder. Every follower the copier opened is closed, and copying stops until you delete the file. To pause without closing anything, set mode = Off.

Prop firm accounts
Many prop firms allow copying between your own accounts and ban copying anyone else's trades. Rules differ and change, so read your firm's current rules before you use the copier on an evaluation or funded account. Test on Sim first.
Good to know.
Is it really free?
Yes, with the source included. No subscription, no paid tier.
Can I copy MNQ to NQ, or NQ to MNQ?
Not yet. Followers copy the same instrument as the lead today. Instrument mapping is on the list for a later version.
What if a follower hits its loss limit?
That follower is flattened and sits out until the next day. The lead and the other followers carry on.
Does NinjaTrader need to stay open?
Yes. The copier runs inside NinjaTrader on your PC. A VPS keeps it running when your computer is off.
How fast is the copy?
We don't publish a speed. It depends on your PC, your connection and the market. Run it on Sim and see how it behaves for you.
