Indicator code for trailing stop

Thanks buddy.
                 Now can that be used as Initial stop ...or trailing stop on the charts?  Is it the same code for both, or that is the trailing stop?

Appreciate the help

Gday there,
                  Im using a trailing stop, and also an initial stop in bullcharts/ tradesim scans that works ok in tradesim system ,

Initial stop =  hist(lowest(L,8),1)

Trailing stop = Close<hist(lowest(L,8),1)   

But i want to code it so that i can use it as a indicator when viewing the results on charts...ie formula to make it a indicator..and be able to change the period etc

Just inquiring if anyone knows how to do this.?

cheers...mark
