You can find the latest NinjaTrader download for your purchased software product(s) in the Members Area, at the link below. This page also includes installation instructions.
After importing the NinjaScript package and restarting NinjaTrader, new changes will take effect immediately. You do not need to recreate your 'Accounts Dashboard' windows or remove and add the Enhanced Chart Trader from your windows. For all other indicators, and all software products, Chart windows do not have to be reloaded.
