Problem with Cancelling Orders

[YevhenShynkarenko]

Hello!
I'm developing strategy using some dynamic indicators.
Having trouble to set "flags" for entering.
F.e. I have 2 SMA's which showing me the trend and a variable Crossover which comes true when 2 SMA's crossing each other. And I want ONLY ONE TRADE from ONE crossover. Then - just waiting for another one.

if (CrossAbove(SMA(14), SMA(50), 1){
Crossover = true;
}

The next thing I want is to enter long limit order on price of another indicator, which gives new value every new bar. I will call that value for example (Indie)
So I'm printing:

if (SMA(14)[0] < SMA(50)[0]{
Crossover = false;
}

if (Crossover==true){
EnterLongLimit(Indie, "EnterLong");
Crossover=false;
}

In this case I have next issue - i have only cancels of all orders on the next bar from the order was accepted.

What I'm doing wrong?

Thanks!


Update:
If I'm using just EnterLong() and EnterShort() method this "flag" of variable Crossover works good and I have only one enter from each crossover. But when I'm putting EnterLongLimit - have no entries at all - only cancelling of orders.

Hello YevhenShynkarenko,

Thank you for your inquiry.

The reason why this is occurring is because, with the managed approach, if an order is not re-submitted, then the order is cancelled.

The reason why your EnterLongLimit() order is cancelling is because it is not being called on the next iteration of OnBarUpdate(). You will need to ensure that EnterLongLimit() is called again on the next iteration if you do not wish for this order to be cancelled on the next OnBarUpdate() call.

Please, take a look at this section in the NinjaTrader help guide for further information about the Managed Approach: http://ninjatrader.com/support/helpG...d_approach.htm

One way to get around this is to use this particular overload for your EnterLongLimit() call:

EnterLongLimit(int barsInProgressIndex, bool liveUntilCancelled, int quantity, double limitPrice, string signalName)

If you set the liveUntilCancelled parameter to true, then the order will NOT expire at the end of the bar, but instead remain live until the CancelOrder() method is called or its time in force has been reached.

Big thanks - it worked, but still have troubles with testing.
I have the next code with conditions:

         // Checking for SMA crossover for finding trend up
                   if (CrossAbove(SMA(FastSMA), SMA(SlowSMA), 1))
                    {
                    trendchangesup = true;
                    
                    }
                    //If we have a new crossover - cancel the enter
                    if (SMA(FastSMA)[0] < SMA(SlowSMA)[0])
                    {
                        trendchangesup=false;
                    }
                                    
                
                //If trend is up and was no any other crossovers - enter long
                    if (trendchangesup==true)
                    {
                        EnterLongLimit(0, true, DefaultQuantity, lowerBand,"Long Limit Enter");
                        
                        Print("Enter Long" + Time[0].ToString());
                        trendchangesup=false;
}

But in fact I see next thing: SMA's are already in downtrend and variable "trendchangesup" must be false and have no enter to Long. But I have it!



The variable lowerBand is
double lowerBand = Bollinger(2, 55).Lower[0];

What I'm doing wrong?
Thanks!

Hello YevhenShynkarenko,

I would suggest debugging your code to see if you are getting the values that you are expecting.

Here is a helpful link on our support forum that details how you can debug your code: http://ninjatrader.com/support/forum...58&postcount=1

I would suggest testing to see if your second if statement triggers or not. Print the SMA(FastSMA)[0] and SMA[SlowSMA)[0] values.

Yes, they are printing me right values - just tried that.

Hello YevhenShynkarenko,

The output provided does not paint a clear picture of what's going on.

I would suggest printing the times for those variables as well and compare it to the time that your enter long limit was submitted.

Was (SMA(FastSMA)[0] < SMA(SlowSMA)[0]) true at the time the limit order was submitted?

I did this.
Here is the code

                    if (SMA(FastSMA)[0] < SMA(SlowSMA)[0])
                    {
                        Print("!!!ORDER CANCEL FROM LONG!!!" + Time[0].ToString());
                        Print("FastSMA" + SMA(FastSMA)[0]);
                        Print("SlowSMA" + SMA(SlowSMA)[0]);
                        trendchangesup=false;
                    }

And here is the output and enter
