I would like to trigger a signal when the open of a candle crosses the top line of a box.
It's not entirely clear to me which parameter in this script I can address. My attempts to implement the box in a cross tag are always acknowledged with an error message.
So what parameter do I need to address from the u script below to do the cross?
Fehler in 198:18 Cannot call 'box.get_top' with argument 'id'='demand_wavg'. An argument of 'series float' type was used but a 'series box' is expected.
