[amibroker] Re: initial or initialize variable

Hello,

First of all, thank you for the effort, but it does not seem to be the
solution.

I do not agree that I'm trading into the future, because I start with
barsince=0, since I have no buy/sell signal, so that CCI period is 10.
Until I get the first buy/sell counting of bars does not happen. e easy.

Hope to get some help from one of them.

Hans
