The reason for this is that TradeStation checks for the last date and
the last time. If you have several bars with the same last-time
stamp, as you can with tick-based charts, you get the condition true
on all the bars with the same last-time stamp.
Your solution will be true for the first bar of the last date and
last time which is the best I have come up with. (We really would
like the true last bar.)
I usually use:
Vars: LBInit(TRUE);
if LastBarOnChart and LBInit then begin
LBInit = FALSE;
......
end;
This gives the same result.
Also note that the LastBarOnChart function will never be true if you
refer to "Open of next bar" on a time-based chart. This is because it
waits for the next open to do the calculation which never comes on
the LastBarOnChart function.
As PO might say, just another workaround in a buggy application...
