Simple question

[MAX]

I'm doing some tests with a stategy and I'm trying to print a text if my position is flat, using OnBarUpdate:

 protected override void Initialize()
        {
            CalculateOnBarClose = false;
        }

       
        protected override void OnBarUpdate()
        {
			if(Position.MarketPosition == MarketPosition.Flat)
			Print("position flat");
        }

The position is flat, because still no orders have been submitted, but nothing is printed on bar update
I've been using Ninja for a long time but this sounds new to me
Is that something am I missing or am I just tired for an hard day?

I can see print only if I attach the strategy to chart, but I need to use the strategy "activating" it from the Control Center.

Thanks

Hello MAX,

Thank you for your post.

When enabling the strategy on the Strategies tab of the NinjaTrader Control Center does the strategy ever go 'green' or does it stay 'yellow'?

I look forward to your response.

Just solved!

It was because I did not change the Number of Bars required. I now set it up to "0" and everything works.

Thanks.

Sorry to bother, but suddenly I'm facing the same trouble.

Following is my code:

 protected override void Initialize()
        {
            CalculateOnBarClose = false;
			BarsRequired = 0;
        }

     
        protected override void OnBarUpdate()
        {
			if(Close[0] != Close[1])
			Print(Close[0].ToString());
        }

In my opinion I should see Close price printed in the Output Window.

I'm running NT 7.0.1000.11 and, once enabled, the strategy is "green".

As I told you, I've been using NT for many years so I'm suspecting something is not working in my NT.

Could you please give me an hint?

Thanks.

You are trying to access bar[1]. You need to escape it.

if (CurrentBar < 1) return;

at the start of OnBarUpdate() should take care of it in this particular instance.

Thanks koganam for your suggestion.

Patrick, I've sent the log. Thanks.

Hello MAX,

Thank you for those files.

From your log file I see the following error listed several times and each time right before your strategy is disabled:

• Error on loading chart data for 'MYTESTINSTRUMENT 10-12 Default': NinjaTrader data server does not support this instrument, no data available.

Please apply your strategy to a valid instrument in NinjaTrader and then advise if the strategy stays enabled and no errors are shown in the Log tab of the NinjaTrader Control Center.

This is a "fake" instrument I created for tests and simulations and it works fine (I've never had any trouble).
When runs as "simulated data feeds" I've seen the same behaviour of a real market. The strange thing is that I was seeing the market updating on chart but nothing on print.

Anyway I will try with a valid instrument.

Thanks.

I don't know if this is relevant, but I had similar weird issues with strategies when fewer than 20 bars are in the chart.

Make sure you have some historical data and at least 20 bars... If you're using the Sim connection... I bet once you get 20 bars updated that it will start to work.

Hello MAX,

Thank you for your response.

Along with what koganam and BigWaveDave have mentioned, have you looked into making sure you have enough bars on the chart before accessing the bars?

You can do this with the following:

if(CurrentBar < BarsRequired)return;

For information on ensuring you have enough bars before accessing them please visit the following link: http://www.ninjatrader.com/support/f...ead.php?t=3170

Please let me know if you have any questions.

Thanks BigWaveDave. This could be a good reason.
