Hallo, I am trying to run a simple dip buying strategy backtest. The strategy buys the first stock out of the list, which price falls 2% below yesterday close and sell it at close. When I try to run with secod resolution, I alwas get error message: Memory Usage Maxed Out. Am I doing something wrong in the code?

/*

buy intraday the first stock out of the list, which price drops below the yesterday Close * 0.98
