Accessto DOM for indicator

aczk · Postby **aczk** » 30 May 2013

Hi

I am trying to access the DOM values and simply plot a marker on the chart if there is a certain size displayed anywhere in the DOM.
My efforts so far:

Code: Select all

input:	BigSize(20), Offset(5);



if dom_isconnected = true then begin



if dom_asksize(1)[1] > BigSize then plot1(Low-Offset,"Ask1");

if dom_asksize(2)[1]  > BigSize then plot1(Low-Offset,"Ask2");

if dom_asksize(3)[1]  > BigSize then plot1(Low-Offset,"Ask3");

if dom_asksize(4)[1]  > BigSize then plot1(Low-Offset,"Ask4");

if dom_asksize(5)[1]  > BigSize then plot1(Low-Offset,"Ask5");



end;

This plotted dots under the bars, for a second but now only gives me an error message (STD exception). Wonder if anyone has created something like this!!?

Thanks

Hello aczk,

Have you checked the prebuilt indicator code --- Market Depth on Chart --- ?

Yes & the post about the new DOM functions, but I can't get it to work. Is there an example somewhere which specifically uses the "dom_asksize" function ?

Thanks for any feedback

Here is the proper code:

Code: Select all

 input: Length(5), BigSize(20), Offset(5);



if not LastBarOnChart_s then #return;



repeat

	if not dom_isconnected then 

		break;

	

	var: X(0), N(0);

	X = Dom_AsksCount;

	N = IFF(X > Length, Length, X);



	for value1 = 0 to N-1 begin



		if dom_asksize(value1) > BigSize then

		begin

			plot1(Low-Offset,"Ask");

			plot2("Ask" + NumToStr(value1 + 1, 0) );

		end;

	end;

	

until(False);
