Pls HELP.
want to set # of standart deviations for Bollinger bands on a tick chart
0.618 - but the system says "0.618 is not a valid value for Double."
and stays an error .
Quite sure it was possible sometime ago.
Maybe I do smth wrong.
Tried to make it with a comma - "0,618" but it seems to plot smth different
Any info will be great
Thanx !
