Connect NinjaTrader once. Then just open it.
Do this one-time setup and your real prices show up in Nexus Charts and Nexus Replay on their own. There's nothing to turn on after that.
Already set up? Here's all you do
- Open NinjaTrader.
- Log in.
- Make sure you're connected to your prop.
That's it. Nexus Charts and Nexus Replay find it by themselves within a few seconds. Minimize NinjaTrader and trade.
First time: 5 steps
Install the Nexus software
Your dashboard ▸ Setup ▸ Nexus software ▸ Download for Windows. Open Setup ▸
Click Install everything
Close NinjaTrader, open the Nexus software and click Install everything. It adds the Nexus price add-on, built and ready. From now on the add-on starts by itself every time NinjaTrader opens.
Let NinjaTrader log in by itself
In NinjaTrader: Connections ▸ Configure ▸ pick your prop firm or data connection ▸ tick Connect on startup ▸ OK. The Nexus check-up can switch this on for you.
Open NinjaTrader, then Nexus Charts or Nexus Replay
They find it by themselves. The light at the top of Nexus Charts turns green within a few seconds, and Replay shows NinjaTrader connected. If your browser asks to let this site use apps on this device, click Allow. Open Nexus Charts ▸
Get your history for Nexus Replay
In Nexus Replay, flip the switch to Real, pick a market and click Get history. It takes a few minutes per market, then it stays saved on your PC. Open Nexus Replay ▸
Not working?
▶Watch the 8-minute fix: live prices not showing? ↗The light stays red
Is NinjaTrader open and connected? Control Center shows the connection at the bottom left. Then open the Nexus software ▸ Check-up: "Nexus price add-on" should be green. If you just installed it, restart NinjaTrader once. In a browser, click Connect live prices, then Allow when it asks to connect to apps on this device. You only do this once, and the desktop app doesn't ask. Blocked it by mistake? Click the icon left of the web address ▸ Site settings ▸ Local network access ▸ Allow, then reload.
NinjaTrader won't connect, or asks me to update
Update NinjaTrader itself. Your broker can refuse older versions: the connection drops a second or two after it tries, with no clear reason. In NinjaTrader, follow its update prompt, or download the newest version from your NinjaTrader account. Your strategies and settings stay in place.
It says my add-on needs an update
Close NinjaTrader, open the Nexus software, click Install everything, then open NinjaTrader again.
The light is amber
NinjaTrader's prices are arriving late. Check its connection, your internet and your PC clock. The Nexus check-up checks the clock for you.
How far back does Replay go?
As far as your NinjaTrader data connection goes. Replay keeps asking for older months until there are none left. On the Lucid connection we tested, NQ and ES went back to January 2006. Yours may differ.
Do I need NinjaTrader open to use Replay?
Only to get history. Your months stay saved in this browser on this PC, so Replay keeps working with NinjaTrader closed. On another PC or browser, get them once more there.
I don't have NinjaTrader
Nexus Replay still works: leave the switch on Simulated and practice on made-up prices back to 2000, with nothing to set up. Real prices come from your own NinjaTrader once it's connected.
Your prices come from your own NinjaTrader on your PC and never pass through Nexus Algo's servers. Nexus Replay only shows them and never sends an order. Nexus Charts sends an order to NinjaTrader only when you pick a NinjaTrader account, say Yes in NinjaTrader's own window, and place the trade yourself.
