Market Replay + multi-instruments + plotting ... crash

[cls71]

Hello,

if you use the Plot method inside of OnMarketData, the MarketReplay crashes when is rewinded to the begining.

Only occurs with multi-instrument. With one single instrument works ok.

If you don't rewind, no crashes.

The code:

protected override void Initialize()
        {
			Add( "$GBPUSD", BarsPeriod.Id, BarsPeriod.Value );	// Instrumento secundario: GBPUSD
			
            Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
            Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Plot1"));
            
			CalculateOnBarClose	= false;
            Overlay				= false;
			BarsRequired		= 20;
        }

		protected override void OnMarketData( MarketDataEventArgs e )
		{
			switch (BarsInProgress)
			{
				case 0:
		            Plot0.Set(Close[0]);
					break;
				case 1:
		            Plot1.Set(Close[0]);
					break;
			}
		}
		
        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
        }

cls71, it's unfortunately not supported to plot from OnMarketData(). You could set variables there and then plot those in the OnBarUpdate() of your code.
