Actually i want the stoch to go below 20 and after it cross above 20, it'll wait for a macd crossover to buy. but when i backtest it only trades when the stoch cross over and macd cross over happens at the same time.

Hi everyone please help. how do i maintain a crossover condition still on? my conditions are:

1. stoch crossing above value 20
2. macd mainline crossing above signal line
3. buy

but when i backtest this, it only trades when 1&2 happens at the same candle. i want 1 to remain active after the cross and wait for 2 to cross. please help.
