NT8 is a free download. You can use NT8 at no charge.
NT only charges if you trade through their software otherwise its free to use.
CycleTrader software will work with NT8 regardless if you buy NT or not.
How long does the demo last and can I use it on another platform other than NinjaTrader? I don’t have NinjaTrader right now.
Demos last 7 days and it only works on NinjaTrader 8. If you don’t have NT8, then the download is free and they have free live data. If you never buy NT, but want to use CycleTrader, you can for free. NT only charges if you use their platform to trade on.
