As of now we do not offer a free trial or demo of our products, if that changes we will be sure to advertise it in the future.
Please note, every purchase comes with our 30 Day ‘Love It Or Replace It Guarantee’. Which means that you can exchange a purchase within the 30 Day Guarantee time with any indicator or bundle equal to the price you've paid - no questions asked.
If you do like to get a feeling for the quality of our indicators, I would recommend that you take a look at our FREE Indicator of the Month Club, where we send you a free indicator every month. You can learn more about it and sign up right here: https://ninjacators.com/free-ninjatrader-indicator-club/
Please let us know if you do have any additional or other questions, we'll be happy to help
