Q: I am totally confused as to what is happening here as I am getting very different bars on my 3R charts on EW (Eur/Usd+) compared to E10 (Eur/Usd). EW needs 3R to give 3 pips per bar whereas the other is 30R to give 3 pips per bar. Which is correct and how do I rectify this?
A: The R parameter is relative to the number of decimals used in the chart scale.
I will assume your preference is to show the 1/10th pip digit, so lets change EW to show 5 decimals. In EW go to the chart properties form by pressing CTRL+P on the chart. Change the Price formats from the current #.#### selections to the #.##### (5 decimal) selections.
