how to change/Modify Stoch Period depends on other conditions

[Jtex555]

Hi
I need help with this one please

i would like to change Stoch Indicator Period depend on the the distance between 2 MA 20 and 100
for example if 100 MA - 20 MA = 50 that will be added to the Stoch period ex = Xperiod+50
provided that Stoch Value is below 80 and if above 80 the formula will stop or pause and so on

thank you in advance

Take both MA values and insert them into two different variables. Then compare both values to know the distance and insert it into a third variable. That last one will be the one you will need for the stoch period.
