Hi, i recently started doing formulas for automated trading. I dont understand how my portfolio backtest (of dayly  data that comes with downloading amibroker) is positive and when i do a individual backtest all companies (except 1 ) is negative.

Can someone explain me why there are discrepancies between portfolio and individual backtest?

Does amibroker index the portfolio?

Thank for your time.

You are taking DIFFERENT trades, that is why

Start reading the manual:


Your question has about the same sense as asking "why 100 cars with one person inside each go faster than 1 car with 100 persons inside"
