Monthly options expiration for the year 2020.
Also you can set a flag X no. of days before the expiration date. I use it at as marker to take off existing positions in expiration week or roll to next expiration date or to place new trades.
Happy new year 2020 and all the best traders.

Category is difficult with this one. I chose ROC as the closest as this measures the historical % of a given change amount.
This indicator is in a separate panel above or below the main chart. I use it only for Options trading to help with probability reckoning.
Use it (at your own risk) and the code freely and please ask any questions, glad...
