hi
I am trying to create marking of the bid & ask price on the chart, works, see my code:
 
Code
variables:	var0( 0 ),var1( 0 ) ;
Input:	offset(3);	
if GetAppInfo( aiRealTimeCalc ) = 1 then                                           
	begin
	var0 = InsideBid ;
	var1 = InsideAsk ;
	
	Plot1[-offset]( var0, "Bid");
	Plot2[-offset]( var1, "Ask");
	end ;
...this displays two dots in front of the bar showing the bid&ask, but....

I only want to show those for the current bar and get rid of the past ones on the chart in order not to leave a useless trail of bid&ask markets behind

help anyone thx!!!

aczk,

here is a quick and dirty solution that does the trick by removing the old plots.

Regards,
ABCTG

 
Code
variables:	var0( 0 ),var1( 0 ) ;
Input:	offset(3);	
if GetAppInfo( aiRealTimeCalc ) = 1 then                                           
	begin
	var0 = InsideBid ;
	var1 = InsideAsk ;
	
	NoPlot[-offset+1](1);
	NoPlot[-offset+1](2);	
	
	Plot1[-offset]( var0, "Bid");
	Plot2[-offset]( var1, "Ask");
	end ;

Instead of continuously removing the plot from the previous bar you could also simply remove the plots for the current bar when this bar is closed:

 
Code
variables:	var0( 0 ),var1( 0 ) ;
Input:	offset(3);	
if GetAppInfo( aiRealTimeCalc ) = 1 then                                           
	begin
	var0 = InsideBid ;
	var1 = InsideAsk ;
			
	Plot1[-offset]( var0, "Bid");
	Plot2[-offset]( var1, "Ask");
	
	if BarStatus(1) = 2 then
	begin
		NoPlot[-offset](1);
		NoPlot[-offset](2);
	end;
end ;
Regards,
ABCTG
