Simple modification on Stoch Cross EA

Hi,

I need simple modification on Stoch Cross EA...

Current rules for the EA:

open: long when red line crossed blue line below 20 
close: when blue line crossed red line above 80

close: when blue line crossed red line below 20

the EA will open another trade right after it closed the previous trade

Modification needed:

1. Open and close trade

close: when blue line crossed red line anywhere between 0-100

open: short when blue line crossed red line above 80

close: when red line crossed blue line anywhere between 0-110

This is quite tricky when both lines crossed each other at below 20 or at above 80 more than once (please refer image)

2. Add Input

- use risk factor

 I will share the EA once developer chosen.

Thanks,
