Hi guys

it happened again this morning when opening my chartbook: I'm using 20 K trades per bar chart, with bolllinger bands studies.
the bollinger bands were not on screen, the software had erased the calculation (from previous week) so it started from scratch and had to wait to see them on screen again (20 period).
it is not the fist time it happens. What is the reason for it? it seems random (this does not happen for VWAP for example)

please advise

thanks

How much data do you have loaded in the chart? How many bars are present when you first open the chartbook?
