I see that Ninja Trader allows data capture (big plus) but it's not clear to me that I can do percent change charts on Ninja (huge minus). Basic charting options are not readily identifiable for the non-Ninja. And does Ninja have its own native data source? Sourcing data from my home base at TD Ameritrade seems like a recipe for inviting a backdoor exploit of my Ameritrade account. I suspect that Ninja is much richer for backtesting though that's not my present interest.
I really don´t understand why it´s still not possible to get the percent change of each stock with NT 8. You can get this with tos, tc 2000, tradingview.
