Why did my strategy open a position?

Hi

My code below seemed to work previously so I cannot understand why it doesn’t work anymore. Has something changed in PRT or is there a coding error?

Backtesting based on Daily DJI. I have also attached screenshots of the trade day, trigger day and trigger day -1 values of the indicators to assist you. Why did backtesting open a new long position on 16th Dec 2020?

The issue seems to be specifically in relation to the code in lines 33 to 45. In this particular example (see screenshots), x[1] > y[1] AND x[1] > 70 AND x > y are all true so a = 1. If a = 1, then as per line 49, it should not enter into a long position on 16th Dec 2020.

x = AroonUp[10]

y = AroonDown[10]

Please advise. Let me know if you need any further information.

Thanks

Sachin
