hi, i've been learning and testing with a long system ever since I started on AB recently. i'd like to combine the long with a short system to see how it performs under different conditions. I don;t know how and if this is "the way its done in AB". I realise i am new to AB and probably getting ahead of myself without asking the right questions.
2 q's follow from this I suppose:
1. within the same loop that I test for long exits do I include the short system exits ?
2. more importantly, how does AB's portfolio backtester treat each symbol or symbols. does it go thru one symbol at a time from start to end of loop ?
thanks for reading my post and appreciate your thoughts on the subject. any pointers to documentation I may have missed or forum posting gladly appreciated.
