Hi , at each level of the price (dailies) , i want to have 2 lines which provides 20 days high and low.  Similarly i can also have 10 day high and low / 20 days high and lows too . 

please help if this can be done and how . Please note this is not simple moving average . its 20 days high and low lines.
