How to count bars ...?

 
Once I found lowest price in certain period, e.g.:
LPrice=Low[iLowest(NULL,0,MODE_LOW,25,0)];
I would like to get number of bars betweent this lowest and current bar?
 

iLowest(NULL,0,MODE_LOW,25,0) is the number of bars betweent this lowest and current bar

since current bar is 0 always.

 
Pretty simple :-) , thank you very much!!!
