output window

Does Output window have a limit....
I notice after 200 lines of output the output stops completely.

rjngh2005, there is a limit, but the old output should be deleted and replaced by the new output. It should definitely not stop printing output. Sometimes the auto-scrolling will stop, and the new output isn't visible. What sort of script did you use to test this?

I have created my own custom script in NT 6.5
It basically has two timeframes 15 minute and 5 minute

and I am printing the output on every new candle of the 5 minute..

rjngh, thanks for the update. If you restart your computer does the issue still persist? Does this also occur in NinjaTrader 7?

EDIT: I just created a simple script to test this out with NT6.5 (haven't used it in a long time) and it printed 15000 some lines of output.

OnBarUpdate()
{
   Print("current bar number: " + CurrentBar.ToString());
}

This code produced 15565 lines of output on a 1 minute ES 09-11 chart.

Yes...I did not restart the computer
However I did shut NT 6.5 and started it again.
I could try rebooting the computer and report back at end of day.
No...I do not have NT 7

rjngh2005, please see my last post, I edited it with test results. I see 15565 lines of output in my Output Window... can you please attach the script you used so I can test it out on my end?

[rjngh2005]

I shall try again at end of day

[rjngh2005]

I tried a simple script to find where it breaks
Then I tried to introduce a little complexity
That worked too
next I tried this script which failed

Script is attached

rjngh2005, I just ran the most recent strategy you posted and there were no trades generated, no text to the output window, and no error messages in the logs. This means the entry conditions are too restrictive, and are not being met, so no trades are being placed.

Please take a look at the sample multi timeframe strategy that comes with every NinjaTrader installation (Tools -> Edit NinjaScript -> Strategy -> SampleMultiTimeFrame) for guidance on how to create multi-timeframe strategies.

The strategy is a simple strategy of EMA(5), EMA(13)
why are there no trades generated when the chart clearly indicates that EMA(5) , EMA(13) is crossing over.

You will need to debug the script then to see where it exactly breaks, the one you posted would run in real-time going forward only since 'Historical' is used, so there will be no historical / backtest trades.

Bertrand,

I am using Market Replay to test the script.
Could you explain if this will work ?

Your associate tried my script and it failed...
why is this failing ?

rjngh2005,

Market Replay is sufficient for testing realtime behavior. Unfortunately though we will not be able to debug this for you. I suggest you start by adding a bunch of Print()s into your code and track each of its conditions to try and understand what your strategy is doing. If it never trades it either means your orders are just being rejected/ignored or your entry conditions were never satisfied. You can use TraceOrders = true to analyze if your orders were ever submitted or not, but you will need to slowly debug with Print()s to figure out what is going on with your entry conditions.

My logic is perfect in the code.
I have tested this a number of times.
The script starts working as expected however after 70 or 80 bars it quits
The problem is with Ninja not being able to handle computations

rjngh2005,

You need to debug your code and see where it stops. Code only performs exactly as written. If you are running into specific scenarios on the Market Replay you will be able to easily identify it and adjust your code to handle it.
