Asian Range Sweep

[kristaparton]

I am wanting to take the Asian Sweep Low and enter to target the high and vice versa. I have pre defined by previous range with a set time and wrote my strategy but I am struggling to piece together how I need to define the range high and low and my pre_h and pre_l is still picking up current price action as it happens and not staying with the pre defined range. Please could anyone help me string this along.

Thank you in advance
