The problem

Copy-trading prop accounts by hand is a tax on your edge.

[01]

Switching accounts costs fills.

By the time you've clicked through 4 account dropdowns, the trade is gone. Seconds matter. Keystrokes stack up.

account_1 → fill
account_2 → slip -0.75
account_3 → missed
[02]

Ghost stops after a TP fill.

TP hits on one account, but the stop on another stays live — until price walks back through it and blows up the rest of your day.

acct_1: TP filled ✓
acct_2: SL still active
acct_3: SL still active
[03]

Per-account sizing is arithmetic in your head.

50K account, 150K account, 100K account. You're calculating contract quantities instead of reading the tape.

50K × 0.5 = 1c
150K × 1 = 3c
100K × 1 = 2c …focus gone.
Features

Everything a prop firm trader needs from a copier. Nothing they don't.

Mirror any order type

Market, limit, and stop entries copy identically across every connected slave the moment you submit on the master.

Bracket SL/TP copying

Full OCO bracket orders propagate with per-slave multipliers so each account gets its own correctly-sized protection.

Auto-cancel propagation

When your TP fills, every paired stop is cancelled on every slave. No ghost orders. No surprises after you walk away.

Real-time modify sync

Drag your stop up on the chart — every slave updates in the same tick. Same for take profit. Same for order quantity.

Per-slave multipliers

Set 0.5×, 1×, 2×, or any fractional size per account. Sizing math happens once, applies forever.

Offline-safe routing

If a slave account drops, PropSync skips it cleanly. Your live accounts keep mirroring. Reconnect — and the next trade resumes.

How it works

Three steps. One NinjaTrader instance. No cloud.

Everything runs locally as a NinjaScript add-on inside your existing NT8 installation.

STEP 01

Install the NinjaScript add-on

Import the PropSync .zip through NT8's standard add-on importer. Restart, done.

# NinjaTrader 8
Tools → Import → NinjaScript
PropSync_v1.0.zip
STEP 02

Pick your master. Add your slaves.

Select the account you'll trade from, then add each slave with its multiplier. Persistent between sessions.

master: "APEX-2847194"
slaves:
  - "TOPSTEP-150K" × 2.0
  - "MFFU-100K" × 1.0
STEP 03

Trade normally.

Submit, modify, cancel on your master like always. Every slave mirrors you in real time, in the same instance.

FAQ

Questions, answered.

PropSync works with any broker supported by NinjaTrader 8, including prop firm accounts from Apex, Topstep, MyFundedFutures, Bulenox, TakeProfit Trader, and others. All copying happens locally within your NT8 installation — no cloud, no middleman.

PropSync V1 is single-PC only. Your master account and all slave accounts must run in the same NinjaTrader 8 instance on one computer. Multi-PC support may come in a future version.

There's no hard limit. PropSync has been tested with multiple slave accounts simultaneously. Performance depends on your machine and NT8 setup.

PropSync detects offline accounts automatically and skips them without breaking. When the account reconnects, new trades will copy normally.

Your license is lifetime — all future V1 updates included at no extra cost. If PropSync doesn't work for your setup, email support within 14 days of purchase for a full refund.
