pre-Main() called more than once?

[ieng]

Hello. In a backtesting script I've been developing, I found that use of the "highest" series causes pre-Main() to be called more than once.

vHigh = highest(5,high(),inv("D"));

It also causes main() to be called more than once with getBarState == BARSTATE_ALLBARS.

Is this correct behaviour? And if so, is there a work-around?

Thanks,

It is the correct behavior. The highest(), lowest() functions are wrappers calling the upperDonchian() and lowerDonchian() functions. The work-around is to use the upperDonchian() and lowerDonchian()[/i] functions directly
That aside the syntax you are using for highest() is incorrect and should be
vHigh = highest(5,high(inv("D")));
For a complete series of examples on how to write the efs2 functions see this thread

Thanks! That resolved the issue.

You are most welcome.
To add to my previous reply note that the upperDonchian() function is already based on the high() by default so if you are trying to define the highest High series you can write it as
vHigh = upperDonchian(5,inv("D"));
