Fix NinjaTrader Indicator Script

Doan created an initial script and then amendments and add Ons his work has been excellent. Also, as I am not 100% experienced with Ninja trader, he was very patient in explaining how to use editor and import the script. My project is ongoing and will certainly keep using Doan Q. Very highly recommended
