[Mehrok]-Relative Strength Index

I have attempted to modify existing RSI Model and add some more features to it. Below are the features.

DC High Line - Basis Donchian Channel concept i have added high line. Period can be selected in indicator options. Usage: Let's say i am tracking 90 day High period of RSI which will be shown with orange line on chart. If this orange line is breached it means RSI has made new high. Basis position of RSI we can determine if need to be in trade or exit.
DC Low Line - Basis Donchian Channel concept i have added low line. Period can be selected in indicator options. Usage: Let's say i am tracking 90 day Low period of RSI which will be shown with aqua line on chart. If this aqua line is breached it means RSI has made new low. Basis position of RSI we can determine if we can enter the trade or not.
DC MID Line - DC High + DC LOW / 2 gives a mid line which act as important resistance or support level.
Buy and Sell Zone: I have added two dotted lines which clearly indicate 55 and 45 levels in RSI. Above 55 is considered as sell zone and below 45 as buy zone. You can change the settings basis your need.
Mid Line: Indicator also show mid line at RSI 50 level which makes easier to understand if RSI is above mid line or below. It improves visualization of the indicator.
