ISSUE:
The last digits of open and close of the Renko boxes are dependent of the fist open of the chart chart. Chart and studies change when you modify the beginning date of the chart.

Example:
first open of a EURUSD chart =1.30176 ( with box size=0.00010 ) ==> all the open and close prices end by "6"
if I choose an other date for the chart beginning we have:
first open of a EURUSD chart =1.30491 ( with box size=0.00010 ) ==> all the open and close prices end by "1" !!!
If you have studies using close prices then there appearence change !

REQUEST:
It would be interesting to define a parameter "reference price" or a "base price" for Renko chart that allow you to define the last digit.
For example if you want a 0 (zero) for the last digit, you define the "reference price" to 0.00000 or 1.00000. With a 0.00010 box size, all open and close price will be ALWAYS a multiple of the box size ( 1.00010, 1.00020, ..., 1.30170, 1.30180, ... )
Same thing if you want "5" as the last digit. You define "reference price= 0.00005 or 1.00005 ( with a box size greater than 0.00010 )
