Re: [amibroker] Re: AD-NYSE for IB feed, AmiBroker Email List Archive

My attempt at breadth for IB. I am getting the data from IB, but I cannot get AB to "record" the data, so all I get is a flat line across the chart (or 3 flat lines in this case) representing the last values. Is there a way to keep the data throughtout the day so you can see the trend of the breadth? Also, if there is a more efficient way of writing this code, please advise. -jk

Title= "NYSE Adv-Dec Issues";

//Attempt to Plot Advancing - Declining Issues on NYSE

Advancing = GetRTDataForeign( "Bid", "AD-NYSE-NYSE-IND" );

Declining = GetRTDataForeign( "Ask", "AD-NYSE-NYSE-IND" ) * -1;

Breadth = Advancing + Declining;

Plot( Breadth, _DEFAULT_NAME(), ParamColor( "A/D color", colorBlack ), ParamStyle("A/D style", styleThick ) );

Plot( Advancing, "ADV", ParamColor( "ADV color", colorGreen ), ParamStyle("ADV style") );

Plot( Declining, "DEC", ParamColor( "DEC color", colorRed ), ParamStyle("DEC style") );

Can't you use GetRTData() to get the bid and ask?
