Opened masterchat does not update the Channel Price Tag on new Start of Visua waves. To reproduce the behavior:
1. Create the Masterchart with Daily Channel Mark shown (not a horizontal chanel).
2. Close WV
3. Open VW next day. >>>> the Channel Mark shows the same price.
P.S. Possibly the is the same behavior for other Masterchart levels as well (retracements, Holz-Lines etc.) - I did not check
