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.

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 ;
