TL;DR: NinjaTrader brokerage accounts run on Tradovate's infrastructure — which means Trading Floor copies them at the API, no NT8 add-on, no desktop running, no per-machine licenses. Sign in with the same credentials you already use, and your NT accounts join the same floor as your Apex, Topstep, Rithmic and Volumetrica accounts.
The classic way to copy NinjaTrader accounts is an NT8 add-on (Replikanto is the best-known): it copies inside the platform, on your machine, and it's genuinely good at that — see our honest comparison. The API way skips the desktop entirely: because NinjaTrader's brokerage runs on Tradovate infrastructure, a cloud copier can mirror fills across those accounts server-side. Your charts stay in NT; the copying doesn't have to.
This isn't NT-vs-us: trade from NinjaTrader's charts and DOM all day. Trading Floor sits underneath, mirroring your leader's fills across the floor and journaling the results with a P&L calendar and verified share cards.
Two ways: an NT8 add-on copier running on your machine (e.g. Replikanto), or an API-level copier. NinjaTrader brokerage accounts run on Tradovate infrastructure, so Trading Floor copies them from the cloud with nothing installed — ~42ms median engine latency, published live at tradingfloor.me/latency.
Yes — with an API copier. Trading Floor runs NinjaTrader-brokerage, Tradovate, TopstepX, Rithmic and Volumetrica accounts on one floor with one leader.
No. The engine runs server-side; your machine only needs to be on to place the leader's trades, from whatever platform you like.
