Using IntraBarPersist

Postby danilo » 19 Feb 2008

is the word "IntraBarPersist" supported ?

I have tested this piece of code:
-------------------------------------------------------------------
vars: IntraBarPersist intraBarcount(0), lastTime(0);

if (Date <> Date[1]) and (lastTime <> Time) then begin
lastTime = Time;
intraBarcount = 0;
end;

if (lastTime = Time) then intraBarcount = intraBarcount + 1;
--------------------------------------------------------------------

but the variable intraBarcount is never incremented

because as soon as lastTime <> Time, you reset intrabarcount to 0.

Actually the correct piece of code is:

vars: barcount(0), lastTime(0), IntraBarPersist count(0), IntraBarPersist intraBarcount(0);


// (A)
if (Date <> Date[1]) and (lastTime <> Time) then begin
count = 0;
lastTime = Time;
barcount = 0;
intraBarcount = 0;
end;

// (B)
if (lastTime <> Time) then begin
barcount = barcount + 1;
lastTime = Time;
intraBarcount = 0;
end;

// (C)
if (lastTime = Time) then intraBarcount = intraBarcount + 1;

--------------------------------------------------------------
The Part (A) reset all variables at the start of each day and time.

The Part (B) is execute at each change of time frames ad increment the bar counter set the time frame variable and reset the intrabar counter, the problem is that since lastTime is not IntraBarPersist , the Part (B) is excetute at every tick since the value of lastTime is update only at the end of Bar. Making also the variable lastTime IntraBarPersist works !

IntraBarPersist attribute works, but your question is not clear for us.
Could you specify?

Andrew,

the IntraBarPersist works properly, It was a my mistake don't have specified as IntraBarPersist all the involved variables.
