Hi experienced traders! I am trying to find my edge through fading the open in the direction of the pre-open trend ( if it wasn't ranging). I trade NQ. Backtesting thorough October 2015 it worked extremely well, September, so-so. I can't go further because I can't find historical intraday data for NQU15 and previous, so 2 questions;

Any comments on my edge?

How would you choose a profit target?

What are my options for getting the historical data?

Thanks so much!
