MultiCharts: Trading Software for Automated Trading and Backtesting

I'm trying to do something simple, to plot the first 30 minutes range of a trading day.

At the beginning, things were quite simple, I would need to indicate each new trading day and within, each 30 minute range.

So, after doing that, why is the high and low being plotted for the entire trading day and not only for the selected 30 minute range?

What am I missing?

Regards,
Fernando

Code: Select all

Inputs:

	startTime		(930),

	endTime		(1000);



variables:

	stTime			(false),

	sessHi			(-999999),

	sessLo			(+999999),

	sessOp			(0),

	hiValue		(0),

	loValue		(0);

	

if Date <> Date[1] then begin

	if time > startTime and time < endTime then begin

		stTime = true;

		sessHi = -999999;

		sessLo = +999999;

	end;

		sessOp = Open;

end;





if stTime then begin

	if High > SessHi then

		SessHi = High;

	if Low < SessLo then

		SessLo = Low;

		hiValue = SessHi;

		loValue = SessLo;

end;

	



if hiValue <> 0 then

	plot1(hiValue,"Session High");

if loValue <> 0 then

	plot2(loValue,"Session Low");

if sessOp <> 0 then

	plot3(sessOp,"Session Open");

because you did not tell MC to stop plotting...

Hi TJ.

As far as I can see, problem solved, though, if you're able to detect (with your expert eyes

) something that could cause some trouble, please let me know.

Thanks.

I haven't test run your code...

one suggestion:

When writing codes... think in terms of

IF
THEN
ELSE

most bugs happen because people have not thought through the ELSE element.
