DrawDot...

[Mark-]

Hello,

OK. I did that. And it did not solve the problem. The dot is still on the wrong bar. All it does now is give me two dots on the bar where the stragety was started. See the attached screen shot. The dot should be on the current bar.

I seem to be failing to communicate the problem. The DrawDot command field of barsAgo does not draw a dot on the current bar when 0 is used. That is the problem.

Ciao,

OnMarketData is not back-testable.

Therefore, this function will only be called in real-time when your criteria is met.

I don't know why you are seeing this on the bar the strategy was started, but anything in the future after that will only show as the OnMarketData is called in real time.

Mark,

Post up your whole code. As mrlogik pointed out, OnMarketData is for real-time.

Hello,

>Post up your whole code. As mrlogik pointed out, OnMarketData is for real-time.

I can not post the logic. I only removed the logic replaced by X in the code I posted, otherwise that is it. There is no more.

I know it is real-time. That is why I selected it.

We are getting off point, of the dot not being on the currentBar as defined by barsAgo in drawDot.

You did not answer my question, have you looked at the screen shots? Do you see the error?

Mark,

As we have mentioned already. It will plot wherever the dot goes. Unfortunately we cannot assist you further unless you post up the full indicator so we can try it on our end. If you want to change the logic go ahead, but until we have the full indicator as well as the exact steps in which you use the indicator we cannot proceed.

Hey,

It is a strategy not an indicator. "It will plot wherever the dot goes". I do not understand.

This took 3 minutes to write and shows the problem.

All of the dots appear on the bar that the stragety started.

Make a 50 tick chart of ES-030 and you will see a vertical row of blue dots appear on the bar the stragety started.

You have removed the OnBarUpdate section.
Try adding it back in where it was originally.

protected override void OnBarUpdate()
{}

[NinjaTrader_JoshP]

Thank you MJT. As you add back the OnBarUpdate() it will resolve your issues.

[Mark-]

Hello,

OK much better.

It is now on the correct bar but it only is displayed when the bar is closed. I want it to show when I call DrawDot.

The next question is how to get the current price. The price is shown by the indicator on the far right (black pointer). I want the dot to appear on the same horizontal plane.

Thanks to all,

Mark

Mark,
You have "CalculateOnBarClose = true;" in the Initialize section. Change it to false, and it will update every tick. That is still not what you really want which is to update with every change in OnMarketData, but I think that goes well beyond the officially supported features, so don't expect Ninja folks to explain how it's done. I believe you could refresh the chart from within OnMarketData, but have never done that myself.
The way you have it coded now, it will draw a new dot each time.

To get the current price, within DrawDot() change Median[0] to Close[0].

[Mark-]

Hi,

Thanks. Yeah in my real strategy I had set that to false. I have not gotten back to it yet. I was still working on the demo code.

OK. So I guess the Close[0] always has the current price.

Yeah, the real logic is not present. It does not fire that often but when it does I want to get the data on the chart as fast as possible. It is edge triggerd so only one dot will appear on the bar.

Close[0] is the last traded price when in real-time with CalculateOnBarClose = false.

[Mark-]

Hi,

Thanks.

Is there a faster method to get a dot, or really any symbol, on the screen than drawXXX with the symbol at the current bar and current price location.

Mark,

Unfortunately not.

Hello,

OK Thanks.
