Modifying zigzag code in Swing Trading strategy

I'm wondering if there's anyone who is able to guide me of another obstacles to modify the below coding to suit my need. The below listed code will BUY when the swing crosses above zigzag & SELL when swing crosses below zigzag.
However, I don't wished to use the zigzag to enter the trade. What I would like is :-

1). BUY when price > last appeared DOWNBAR high,
a). close when price < LAST UPBAR low,
b). then immediately place a SELL order and will close order when price > last DOWNBAR high

2). SELL when price < last appeared UPBAR low,
a). close when price > LAST DOWNBAR high,
b). then immediately place a BUY order and will close order when price > last UPBAR low

Thanks and best regards.

how result after use this logic sir?

I'm hoping someone who could modify the code above based on my request in order for me to back test before I can tell you the result.

Results will be terrible. ZigZag not a particularly good way of getting levels.

Been there, got that T shirt...
