Hi Tomasz, Thank you for the rapid answer. I have looked into the material you've sent, very clear and straight explanation. The only problem is that even when I put SetRequiredBars(1000, 0) at the very beginning of my script nothing changes - I still see all 300000 bars on the chart.
'Use QuickAFL' in the settings of backtester is checked. What I'm doing wrong ? May be you can provide some primitive script to play with to understand how QuickAFL affects things ? Thanks in advance.
