Nasdaq5048: Bars Back that Price Occurred

Nasdaq5048,

The following indicator draws a trendline between 2 bars for each price that they have in common. Is this what you're trying to do?

Code:
variables:
	TickSize( MinMove / PriceScale ),
	Price( 0 ),
	TLID( 0 );

if CurrentBar > 2 then
begin
	Price = Low;

	while Price <= High
	begin
		if Price >= Low[1] and Price <= High[1] then	
			TLID = TL_NEW(Date[1], Time[1], Price, Date, Time, Price);

		Price = Price + TickSize;
	end;
end;

Re: Nasdaq5048: Bars Back that Price Occurred

Thanks Ant,

This is what i am looking for. I wrote something like this with a long list of array, this is much more CPU efficient.
A couple of questions:

1) What statement should i add if i only want to print the lines from the last bar? and i dont want any history. I tried if lastbaronchart = false then TL_Delete(TLID) and it doesnt work. And i think using the lastbaronchart function will require manual refresh. Is there a way to make it only draw the latest bar and delete everything before the latest bar?

2) It is perfectly what i am looking for on a 5 min chart. When i apply this to the 5000 contracts / bar chart on the ES, it still only plot the first bar when there are multiple bars within the same time. The thought that i have in the other theard is, can we get the TL_new to plot in every bars on the volume chart even they have the same time by adding the IF statement in front of the TL_new.
If time[5] = high[5] then TLID.......
say for example, there are 4 bars with the same time and with different high or different close. It doesnt matter, just something different so we can distinglish the bar we want to plot within the same time.
So, the IF statement could find the right bar (5 bars ago in this case) even bar[6] or bar[7] has the same time.
This is something that i havent tried or dont know how to try. I am just thinking this logic might be able to get around "tradestation only considers the first bar in a series of bars that starts at the same time."

Again, i would really appreciate your help.

Actaully not time[5] = high[5] but to set up a array for all the high with the same time (time[5] in this case) and find the right one by matching the high[5] with all the high that match time[5]

Never mind! it wont work. Even if the right bar was identified, the time would still be the same. So, EL would still go back to start the plot from the first bar of that time.

Never mind also to the only plot last bar thing. As i look into the code, it will probably need a loop to look back for how many bars to plot since it is only design to plot the trendline 1 bar back.
I am perfectly happy with the way it is now. Thanks a lot!
I hope others could make use of this code too because i found it very useful to determine the choppyness of the current market. Better than ADX in my opinion just by looking how bars has the current price been repeated
