Free Simulation Edition

It's Free!
NinjaTrader understands the importance of paper trading in the early stages of your trading career. We also feel that you should not have to pay for software unless you are using it to make money. For this reason, we offer a free unlimited use simulation version of NinjaTrader called NinjaTrader Simulation Edition. Although we cannot guarantee that you will make money, we can guarantee that you will not need to pay us for our trading platform until you are ready to trade live with real money. This flexibility allows you to learn at your own pace and subscribe only when you are ready to put real money on the line.
