SetStopLoss() doubling qty when called a second time

[sjmuk1]

Hi,

I am entering two positions with Entry methods and using SetStopLoss() twice with different fromSignalName values (the two different names of the entry orders) Everything seems fine, I get two separate Stop loss orders at two different prices. However, after the second entry order executes both stop losses increase to the same size as the overall position meaning the stops combined are double the strategy position. For example

Entry 1 Quantity = 5000
Entry 2 Quantity = 5000

I end up with Stop Loss 1 Quanitity = 10000 and stop loss 2 quantity = 10000

Iniitially before Entry 2, Stop loss 1 = 5,000 then after entry 2 both stop loss orders jump to 10000

What might be happening?

Hello sjmuk1,

What is the value of StopTargetHandling when printed from State.DataLoaded?

It prints "ByStrategyPosition" to output which is what I have it set to in set defaults. I have to develop with this setting as it says in the help guide that IB only works with ByStrateyPosition handling, https://ninjatrader.com/support/help...ethandling.htm

Hello sjmuk1,

That would be the issue.

ByStrategyPosition updates the existing stop loss, which you are doing twice.

Use Exit orders (or the unmanaged approach) instead of Set methods to avoid this issue when using Interactive Brokers or TD Ameritrade.

Below are links to examples.

Could you please explain why it is doing this so I understand?

Hello sjmuk1,

StopTargetHandling.ByStrategyPosition does not make unique stop orders with SetStopLoss().

Even though you are using unique signal names, NinjaTrader is ignoring these as there is only one stop loss order being submitted. Each time you place a new entry, this attempts to change the quantity of the stop to cover all entries that make up the strategy position (ByStrategyPosition).

Normally, we would say to use StopTargetHandling.PerEntryExecution, as this would make individual stop loss orders for each entry, but with Interactive Brokers and TD Ameritrade this is not an option. The ByStrategyPosition setting is forced.
The only work around is to use exit orders and stop using set methods.
