How do we identify the current bar in Thinkorswim? Thanks,

If you mean the last (most recent) bar on a chart then perhaps this:
Code:
``def current_bar = if BarNumber() == max(BarNumber());``
but I haven't tested it.

Thanks Mashume, that helps

It is if statement, should there be else statement?

You can write it this way:
Code:
``def current_bar = if BarNumber() == max(BarNumber()) then 1 else 0;``
and it is cleaner, but I believe that ToS will default the version without a 'then' and an 'else' to be true or false such that later you could do something like:
Code:
``plot buy = if current_bar then low else double.nan;``
though there wouldn't really be a point to buying the current bar all the time but the example code should work.

I should not be a lazy programmer. Explicit instructions are always better than implicit.
the second buy plot should then be:
Code:
``plot buy = if current_bar == 1 then low else double.nan;``

much easier to read six months from now when you wonder what on earth your code was supposed to do.

Thanks, I want to scan for current bar crossing fib level. how do we scan for current bar crosses above or below fib levels properly when fibfan is either upward or downward?
