Partial Exit - named signal exit stop not updated

[MicroTrends]

As a trader i am long 10,
I take 50% of my position at target N, move to breakeven and let the other position quantity run...

Enter a position long 10 name "signal1"
place a stop fromSignal "signal1"

e.g
SetStopLoss("signal1", CalculationMode.Ticks, 10,SimulatedStop);

exit half the position

exitLong("signal1",5)

5 is exited
5 long
stop is still qty 10

I would expect the stop order quantity to get updated - but it is left on....Quantity 10
meaning you can an unwanted fill of 5

That must be a bug?

Hello microtrends,

I'm seeking clarification on this and will update this thread tomorrow, Tuesday.

This is limitation of managed order system. In order to scale out of a strategy, we always recommend first scaling in with distinct entry names.

You may also consider using the unmanaged order system if you prefer not to scale in first.

As you can see I am scaling and scaling out with a distinct order names.
I am using your patterns.

The difference is that I am not exiting with the full quantity..

The problem is the associated stoploss is not updated when an exit is performed.
long Qty 10
Stop qty 10
Exit qty 5

Stop hit fill 10

position short 5

If the stop is hit, it will then fill and overfill by half
leaving an unmanaged order in the system.

This is a bug or if not an extremely dangerous limitation..?

The documentation guide should say that this is not possible or an order reject should occur at least....

A Work around then is:
To not allow partial quantity exits for "1 signal"
This is very inflexible for professional traders - and I cannot using ninjaTrader fullfill commercial requirements due to this - unless i try workarounds.

You cannot rely on the fact that 2 distinct orders will be sufficient - you may be long in 2 seperate trade entry signals of 20M or 20lots and exit 1 signal - then you want to exit half the remaining. For traders with more than 10K this is common.

One way I will try then is to cancel the stop and recreate it perhaps it will have the correct quantity in. Or try to change and the update the order....

Please can you place this functionality on the suggested improvements?
As it does look like a bug, could provide some very slick trading capabilities for pro traders

In your example, you use only one signal name for your entries. To scale out, you must scale in with distinct entry names, like:

EnterLong(5, "signal1");
EnterLong(5, "signal2");

The exits you use could then be:
ExitLong(5, "exitname", "signal1");
SetStopLoss("signal2", CalculationMode.Ticks, 10, false);

A sample scale out strategy is available here:
