Very strange here: I just applied an indicator on an indicator, in this case
Bollinger Band on RMI indicator. When, and only when, the B bands are
squeezing, do I have this: the value of the BBand top and bottom totally
change, FOR THE SAME BAR, when I scroll the chart a little bit to the left or
to the right. No only does the value changes but I can see the change on the
chart with the BBand having its shape modified.
Below is the formula, can someone explain this ???
Many thanks,
Carl
