Ara, the Help 
says:SYNTAX BarsSince( ARRAY )RETURNSARRAYFUNCTION 
Calculates the number of bars (time 
periods) that have passed since ARRAY was true (or 
1)Perhaps BarsSince() cannot be used 
with ticks since Ticks are not timebased. It may be related to the fact that 
there is no unique answer, as time is in seconds and there could be many bars in 
one second. Don't ask me why but the code below "appears" to work, please 
let me know if this turns out to be correct because i am also working with 
ticks.
