Historical bid And Ask Minute Series

[esignal]

h, i try to plot Historica Volume bid and ask..but
the result is displays the spread ask and bid :

	if ((State==State.Historical) && (BarsInProgress==1))
			{
								
				Ask[0]=BarsArray[0].GetAsk(CurrentBars[0]);
				Bid[0]=BarsArray[0].GetBid(CurrentBars[0]);

How do I display the volume bid-ask ?

Thanks a lot of..,

Hello esignal,

You can either add a secondary series of ask and secondary series of bid and call the volume of that data series.

Or you can use GetCurrentAskVolume() and GetCurrentBidVolume().

Definition
Returns the current ask volume.


I try to plot

	Ask[0]=GetCurrentAskVolume(CurrentBars[0]);
       Bid[0]=GetCurrentBidVolume(CurrentBars[0]);

I see empty chart

Hello esignal,

You will need to add a secondary data series of ask and a secondary series of bid and check the volume on each data series.

AddDataSeries(Instrument.FullName, BarsPeriodType.Minute, 1, MarketDataType.Ask)
AddDataSeries(string instrumentName, BarsPeriodType periodType, int period, MarketDataType marketDataType)

Then use Volumes[1][0] to check the volume on each minute bar.

If you want each ticks volume, add a tick series instead of a minute series.
