I am having a big issue with QC. I want to run my algo on 15 min, 30 min, 1 hr, 2 hr time frames but I cant run them for longer than a couple months back or else the back test will stop short because it hits its time limit. I want to analyze how this algo runs with different parameters with different aggregation times. The goals is to look at different parametes over multiple years, but because of this time out issue, that will take hundreds of hours and tons of back tests as well as continuity issues!!... Please help!
