Thanks for the reply, but OOPPSS, what a screw up I just made.It's 
been a looong day...  
I meant an "Expert Advisor", not an "Explorer" Sorry about that.
Thanks

An Init function might be part of the solution and is usually 
helpful with BarsSince() / ValueWhen() type functions. Another 
useful device is to pass an N/A result to one of the Forum DLL 
functions (Summing 1 period of the troublesome output should do it). 
This converts N/A to 0 which is much easier to work with. If you can 
manipulate your code to output zero when there has been no signal in 
the scanned range you then have the opportunity to filter out all 
invalid/zero results.

sufficient bars to produce the required result. While this is not 
always possible, using "Minimum Records" is guaranteed to fail when 
BarsSince() / ValueWhen() type functions are included in exploration 
formulas.
