OCO order automatically cancelled

[BillyRayValentine]

Hi,

I created a simple indicator that highlights occurences of double inside bars. It plots this on the chart and also outputs a bool=true when a double inside bar is detected.

I created a basic strategy to verify the signals reliability. It will create a manual OCO order to capture the breakout after a double inside bar is detected.

I have two problems that I am struggling with;

1) One of the OCO orders is automatically thrown out after the first double inside bar is detected. The error message doesnt help me too much and I am not sure where to start looking for a fix. All subsequent OCO orders seem to get created successfully.

2) The strategy appears to be detecting erroneous occurences of double inside bars. I have added print statements within the indicator and the strategy; the indicator seems to be running OK internally but the strategy looks like it is detecting bool=true on the indicator output. I suspect that the strategy is handling things correctly and that it's the way that my indicator is creating it's bool output that is the problem.

The OCO order management is still very basic - I am just trying to test the validity of the indicator so please dont laugh

I appreciate your help and comments.

Thanks!

Billy, with an approach like this in the managed NT mode you would easily run into the internal order handling rules - http://www.ninjatrader.com/support/h...d_approach.htm (bottom section here). You would need to enable the use of TraceOrders in your strategy (Initialize() TraceOrders = true; ) and then monitor the output window while running the strategy -

The indicator itself looks fine to - are you running the calling strategy on bar close or updating each tick?

Thanks,

Hi Bertrand,

Thanks for the reply. I will enable TraceOrders and see how I get on.

In the strategy I have "CalculateOnBarClose = true" and my code is within an OnBarUpdate() section.
The behaviour is strange and I cant figure it out. The indicator is fairly simple and appears to work as intended. When embedded in my strategy it appears to output erroneous bool outputs.

Thanks

Ray, I'm seeing the same here on my end - will look into - btw: on which version are of NT are you currently working?

You can check it under Help > About.

Thanks,

Ray, here the cause - you need to reposition the set to false in the indicator - otherwise it's not reset as needed staying in 'true'.

	
if (CurrentBar == 0)
{
dIB.Set(false);
}

if (CurrentBar > 3)
{
if ((High[0] <= High[1]) && (High[1] <= High[2]) && (Low[0] >= Low[1]) && (Low[1] >= Low[2]))

{
DrawLine("upper" + CurrentBar,false,2,High[2],0,High[0],Color.Red,DashStyle.Solid,3);
DrawLine("lower" + CurrentBar,false,2,Low[2],0,Low[0],Color.Red,DashStyle.Solid,3);
dIB.Set(true);
//Print(Time[0] + " Indicator = true");
}
else
dIB.Set(false);
}

D'Oh, schoolboy error

Thanks again Bertrand!
