This is probably the incorrect forum, but I do have some questions related to automated trading as that is my goal in the end. If there is a better place to post general questions for a newb, please let me know

I am thinking about starting to trade and test some strategies with NinjaTrader. Having said that, I am really new to this. Currently I have my trading on Fidelity.
I am considering moving to IB as broker and NinjaTrader for the front office trading platform.
Regarding the Trading, I have been listening to Trendfollowing.com and will probably start with one of his strategies or one of my own which looks at end of day prices on equity and forex markets. Some of my questions about this are listed below. This is just a brain dump and shotgun blast on my questions
1. Can a end of day price strategy which compares today's price with prices over the last 140 days closing prices (average momentum) be programmed? I currently have this in Excel across several worksheets.
2. What monthly fees should I be expecting for automated trading across forex, commodities, equities ( us and foreign markets) via IB and Ninjatrader?
3. Can I test my strategies for free or will paid data feeds be needed to get minute, 5 min, hourly, 4 hour, daily etc prices for commodity, Forex and equity prices?
Thank you and best regards
