AFL Collection without formula references FUTURE quotes

hi,
i tried many afl available on net ...most of them are showing "It seems that the formula references FUTURE quotes." so they can not be used.Even patternexplorer afl also shows this message.

Can anyone explain is these AFL really can not be used for real time?

Please post collection of afl which do not refer to future quotes?

Thanks,
Paresh

This not always true, but true most of times. I have Good AFL, that is useful in real time, but I have used too much IIF, valuewhen, Ref, operators, timenum, bars conditions in it. So the automatic check system tell that it will not be useful in real because too many IF BUT are used in it. While in real its useful.

I have answered your question. Now dont ask for the same AFL
