ExitShort ExitLong behaviour

[stormze]

Hello, Im seeing some kind of problem with a strategy executed in real time on the simulated NT account...
This is the code:

if(/*some short condition*/)
{
if(Position.Quantity > 0)
ExitLong(1, 1, "TO_ExitLong", "TO_EnterLong");
if((ToTime(Time[0]) > 103000 && ToTime(Time[0]) < 163000))
EnterShort(1, 1, "TO_EnterShort");
}
elseif(/*some long condition*/)
{
if(Position.Quantity > 0)
ExitShort(1, 1, "TO_ExitShort", "TO_EnterShort");
if((ToTime(Time[0]) > 103000 && ToTime(Time[0]) < 163000))
EnterLong(1, 1, "TO_EnterLong");
}

The problem is that the long condition is executing 2 orders of buy and the short part just closes that 2 positions... (the script never go short)
ExitShort is not acting well, why is that ?

Note: this started happening since I manually closed one of the orders that the script submitted

stormze,

If you want to reverse there is no need to place ExitShort then EnterLong orders like that. Just call EnterLong and just call EnterShort. If you were in an opposing position it will automatically close that position first and then get you into your long/short.

I know but I only want to reverse on some circustances and just close the actual position on others.
Apparently when Im long 1 contract and I do a close, instead of selling that contract, is buying another one

[NinjaTrader_Josh]

If you were long and you called ExitLong() it will close the position. If in addition you called EnterShort() you will for sure get the additional short. You will need to debug your orders to see which are being placed with TraceOrders = true.

Ok I will try to collect some logs with TraceOrders = true
But may be there is a bug here, I think what happened is the following:

- Script executed EnterShort of 1 contract
- I manually closed that position and went to flat
- Script executed an ExitShort of 1 contract but it didnt realized that it was already flat and bought 1 contract
- Script executed an EnterLong of 1 contract and bought another contract being long 2 contracts... and so on

[NinjaTrader_Josh]

Could happen since your code is never checking for a flat. Plus inflight executions can occur. If the execution has not been reported back yet and you still submit a new order it will go through.

[stormze]

Ah interesting...
I tryed to check for a flat on my code with

if(Position.Quantity > 0)
close actual position

Is that wrong or some other better way to do it ? Note that all orders are submitted to only one ticker but its not the main ticker

[NinjaTrader_Bertrand]

You can use Position.MarketPosition for checking if you're flat or not - http://www.ninjatrader-support.com/HelpGuideV6/MarketPosition.html

Ok I still have the problem.
EnterLong of 1 contract is buiyng me 2 contracts being flat, and I can't change that behaviour :(
Is acting like if it were short 1 contract.
I tryed reseting the Sim101 db restarting NT but nothing.
What can I do

stormze,

You need to use TraceOrders = true to see what is going on. If you really are flat it will never buy 2 if the order was submitted as 1. Changes you make to the code need to be compiled by pressing F5 in the compiler and changes are only reflected AFTER you start a new instance of the strategy.

[stormze]

I dont see anything unusual with TraceOrders = true, prior EnterLong is baing executed I see a "Close position" order generated automatically, I want to prevent this or reset the counter it has. How NT knows that it need to close a position ???
Yea I also reload the strategy for every change...

stormze,

It is evident your signal tracking has gone awry. You will need to debug your strategy and find exactly where it happens. You have a lot of Enter/Exits mixing and matching everywhere. You will need to check them by hand.
