DrawDot on current bar

[Mindset]

DrawDot("tag"+CurrentBar,true,Time[0],TheBid,Color.Cyan);

Draws a dot on bar [1]?

Mindset,

What is your CalculateOnBarClose setting?

[Mindset]

Calculate on bar close

Set to False.
Y co ord is correct but X seems to be 1 bar off.

[NinjaTrader_JoshP]

Seems to work fine here when I set it to the high of each bar.

Update

ok I was using OnMarketData. If I set the condition and use {} it plots Bar[1] if I don't use {} it plots CurrentBar ie as expected.

[NinjaTrader_JoshP]

Unfortunately I am not sure I follow you. It would probably be best if you could just post a sample as I have done. Thank you.

Josh,
your code is in OnBarUpdate. Place the code in OnMarketData. the dot will draw on CurrnetBar - 1 and not on the currentbar.

protected override void [B]OnMarketData[/B](MarketDataEventArgs e)
{
      if (e.MarketDataType == MarketDataType.Last && e.Volume >=10)
      {
                DrawDot("dot" + dotcount,false,0,e.Price,Color.YellowGreen);
                dotcount +=1;

       }        
}

Drawdot

No, today it works fine inside the curly braces under onmarketdata
I mean it definitely was plotting bar[1] and not bar[0] even after I restarted NT7B9.

Code segment

    protected override void OnMarketData(MarketDataEventArgs e)
        {
			
			if (e.MarketData.Ask != null)
                        {
				TheAsk = e.MarketData.Ask.Price;
			}
			if (e.MarketData.Bid != null)
                        {
				TheBid = e.MarketData.Bid.Price;
			}
if(TheBid == double.MinValue || TheAsk == double.MinValue) return;

		if (e.MarketDataType != MarketDataType.Last)
                return;
		
			
	        if  (e.Volume >= Vol_Lim) 
					
{ 	
	 mystr =   e.Time.ToString("t") + " " +  String.Format(" [{0}] ",e.Volume.ToString("N0") ) + String.Format("@ {0} ", e.Price.ToString());

	
	
	Print(Environment.NewLine);
Print( e.Time.ToString("T") + " " + String.Format(" @ {0} ", e.Price.ToString()) +  String.Format(" for {0} Lots ,e.Volume.ToString("N0")));
	
	if(e.Volume > Vol_Lim * 3)
	
	{
		
		if(e.Price <=TheBid)
	DrawDot("tag"+CurrentBar,true,Time[0],TheBid,Color.Cyan);	
		else
	DrawDot("tag"+CurrentBar,true,Time[0],TheAsk,Color.Cyan);	
	
	}

}

seems it is off by one bar. the currentbar is having an index of -1.

[NinjaTrader_JoshP]

Guys,

OnMarketData() and OnMarketDepth() are not tied to any bars series. This means their events are not linked to [] indexes. Further meaning, that going [0] may very well be the previous bar as no OnBarUpdate() was triggered for the newly building bar yet while you are receiving OnMarketData/Depth() updates.

[Mindset]

onmarket data

Josh

I get that - but I don't seem to have the issue anymore - my indicator has worked fine real time all day.
An onmarketdata event doesn't assume an on bar update but in reality I don't find it an issue.
Must have just been an odd install or something.

[bukkan]

Thanks Josh for the clarification.

if i do this:

DrawDot("dot" + dotcount,false,0,High[0],Color.YellowGreen);

the dot is drawn on Bar[0]

but if i do this:

DrawDot("dot" + dotcount,false,0,e.Price,Color.YellowGreen);

then the dot is drawn on Bar[1]. now this can be done in OnMakretData etc as Josh rightly clarified as the price is not linked to []

thanks again Josh.

EDIT: FIXED IT by using barsAgo (0) instead of Time[0].

I'm observing this too and i'm not using onMarketData.

                y = Low[0] - 3*TickSize;
                DrawDot("Dot"+CurrentBar, true, Time[0], y, color);

Sometimes it's drawing on the current bar and sometimes 1 bar ago. I have been trying to figure it out for a while now when I got the idea to search this thread.

I don't know what the time parameter is for (it wasn't there in 6.5) and I don't know what to put.

This is the same code that never had this problem with 6.5.
