[amibroker] Re: Synchronization problem between panes using Static array variables

I just wrote a CCI indicator that will pass the statics as I wrote. I wrote a MA program that will accept it. This will cause a buy/sell signal and I use plot shapes to see the buy and sell signals in the MA indicator. I ran it on 1, 5 and 15 minute charts and changed tickers. I can change the tickers and time frames and it works perfectly. 

But one thing you need to know is that AB scans your indicators top to bottom so the input indicators have to be on top and the receiving ones below it.

One real easy way to test it is to use printf() and write the values you are receiving to the interpretation window in the receiving indicator. Then check the value received with the sending chart.
