Stochastic w/ Crossover Alerts (by WJ)

NOTE:
// STOCHASTIC CODE TAKEN FROM DEFAULT INDICATOR
// I HAVE ONLY MADE SOME ADJUSTMENTS FOR VISUAL AID
// I MADE THIS FOR MY OWN USE BUT HAVE DECIDED TO PUBLISH AND SHARE IN CASE ANYBODY WANTS TO USE IT

This is the normal default built-in Stochastic indicator which I have added some stuff for visual aid:

• Stochastic background turns green when K line crosses D line UPWARDS, D line is below the oversold level, and price is above selected MA
  
• Stochastic background turns red when K line crosses D line DOWNWARDS, D line is above the overbought level, and price is below selected MA
  
• Alert notification on the crossover candle with background colour change when conditions are met (MA filter)
  

릴리즈 노트:

Changed alerts to K line detection as it's better, apologies for the confusion and trouble of re-adding the indicator

릴리즈 노트:

Changed to both K and D line as it seems to be the best solution

릴리즈 노트:

Added sharper detection mode (toggleable) that also takes whether the k and d lines of the candle before crossover candle into account

릴리즈 노트:

Added middle line

릴리즈 노트:

Added toggleable background colour change when k line crosses 50

릴리즈 노트:

Added new alerts for non-OBOS crossovers

릴리즈 노트:

MA checking was slightly wrong (used OPEN instead of CLOSE), fixed

릴리즈 노트:

Updated some stuff
