Here I bring you ASI, (Absolute Strength Indicator). I saw it in Trading view. I tried simultaneously while I operating in TOS platform, and now finally get it converted with the HELP a friend IgorF. You can change and play with the settings as you like and try the 3 option that come inside as RSI, Stochastic and ADX.

Thank you...It does work better on the Daily I discovered. Good Indicator.
 
for scanner add these 2 lines at the bottom of the script, select from the input your signal and make true!

Code: 
plot upBull = sgnBull crosses above sgnBear;

plot dnBear = sgnBull crosses below sgnBear;
 
This works just fine for me...
