Hello mrtools.

I'm playing with an indicator that draws 2 lines between 0 - 100 value.

By default setting, Green line (using Low Price) reaches to 0 value impulsively
but Red line (using High Price) doesn't reaches to 100 value impulsively.
I think the red line should work the same as the green line.

I have had the same experience before with other indicators that use highs and lows, or maximum and minimum of price.
(I forgot the name of the indicator.......)
Do you know why like this happens ?
Because of the spread?
price data comes from only ask price something like this ?

Could you take a look the code please ?
