Please read the manual
Special attention should be given to the picture that shows how entry and signals are matched and how redundant ones are removed. See also SetBacktestMode function that controls what signals are kept and which are not.
Generally you should not be using CBT unless you understand the core principles explained in very detail in the manual.
Another important thing is PADDING. Depending on pad and align option, the quote might be padded to reference symbol and the absolute bar number in CBT that represent ALL bars that are present in any of the symbols under test might NOT be the bar number that you are referring to DO NOT use absolute hard coded bar numbers!!!!
Use date time instead. ONLY date times are guaranteed to accurately represent bars. Bar numbers are NOT ! Bar numbers vary when you use padding, other unaligned symbols, quickafl, etc.
