TickVolume - Displayed on the chart
27 Oct 2013, 16:53

Hi,
in this 3d:

is shown the following example for information displayed on the chart:

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
 
namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC)]
    public class MultiSymbolMarketInfo : Indicator
    {
        private Symbol symbol1;
        private Symbol symbol2;
        private Symbol symbol3;
 
        [Parameter(DefaultValue = "EURGBP")]
        public string Symbol1 { get; set; }
 
        [Parameter(DefaultValue = "GBPUSD")]
        public string Symbol2 { get; set; }
 
        [Parameter(DefaultValue = "EURUSD")]
        public string Symbol3 { get; set; }
 
        protected override void Initialize()
        {
            symbol1 = MarketData.GetSymbol(Symbol1);
            symbol2 = MarketData.GetSymbol(Symbol2);
            symbol3 = MarketData.GetSymbol(Symbol3);
        }
 
        public override void Calculate(int index)
        {
            if (!IsLastBar)
                return;
 
            var text = FormatSymbol(symbol1) + "\n" + FormatSymbol(symbol2) + "\n" + FormatSymbol(symbol3);
 
            ChartObjects.DrawText("symbol1", text, StaticPosition.TopLeft, Colors.Lime);
        }
 
        private string FormatSymbol(Symbol symbol)
        {
            var spread = Math.Round(symbol.Spread / symbol.PipSize, 1);
            return string.Format("{0}\t Ask: {1}\t Bid: {2}\t Spread: {3}", symbol.Code, symbol.Ask, symbol.Bid, spread);
 
        }
    }
}

I would like to also see the information "TickVolume".
I understand that I must use this:

public override void Calculate(int index)
{
 
    double currentVolume = MarketSeries.TickVolume[index];
    double previousVolume = MarketSeries.TickVolume[index-1];
  
}

I tried to change the code but failed.
Can you help me, please?

If you are trying to access the tick volume of a specific series of another symbol then:

private MarketSeries series1;
//...
protected override void Initialize()
{
   symbol1 = MarketData.GetSymbol(Symbol1);
   //...
   series1 = MarketData.GetSeries(symbol1, TimeFrame);
   //...
}
public override void Calculate(int index)
{
   //...
   var openTime = MarketSeries.OpenTime[index];
   var series1Index = GetIndexByDate(series1, openTime);
   var symbol1Volume = series1.TickVolume[series1Index];
}

See GetIndexByDate method in this example
