Synapse Pro runs inside NinjaTrader and keeps your accounts in sync. No extra software, no scripts to maintain.
Synapse Pro is a NinjaTrader addon that copies your lead account's trades to as many follower accounts as you need. Entries, adds, reduces, and closes — all replicated the moment your lead executes.
It also handles risk management per account: loss limits, take profit locks, max contract sizing, and max trades per timeframe. If things go sideways, there's an emergency flatten button that closes everything across all accounts at once.
The External Relay lets you forward trades outside NinjaTrader — to Discord for notifications, to ProjectX for TopstepX accounts, or to the Synapse server to mirror into MT5 or other platforms.
Synapse Pro handles everything within NinjaTrader. These add-ons extend it to other platforms and setups.
A NinjaTrader strategy that connects to the Synapse server and mirrors positions from any Synapse Pro trader into your NT account. Use it to follow someone else, or to mirror your own trades to a second machine or account.
Trade from NinjaTrader and have your positions mirrored into MT5 automatically. Synapse Pro sends signals via the External Relay; the MT5 Listener EA receives and executes them.
Trade from MT5 and have your positions copied into NinjaTrader 8. The MT5 Trader EA sends signals to the Synapse server; the NinjaTrader Listener strategy executes them. Works with any MT5 broker — lot sizes are normalized automatically.
The Synapse server isn't tied to any specific platform. More integrations are in progress — if there's a platform you need, reach out and we'll look into it.
Most traders end up cobbling together 3–4 separate tools to do what Synapse does out of the box.
