Hello, I am looking to create a buy signal when a green bar takes over the red. So when the 8 ema above the 21 ema and a red bar closes or touches the 21 ema, the next green bar that takes over the high of the red bar creates a buy trigger. The trigger does not have to wait until the green bar closes but as long as that green bar breaks the high of the red bar. is it possible? Thank you in advance.
