[amibroker] Re: Why writeif returns the same value all the time?

["j0etr4der" <j0etr4der@xxxxxxxxx>]

I tried on a watchlist with 60 stocks.  There were both Trend UP and Trend Downs, BUT for any one stock, the results were the same (either  all Up or all down Down.)  Something else is wrong other than WriteIf.

Good luck.
