Multiple Strategies with same instrument

[DividedSky]

I am trying to run multiple strategies on the same instrument on NT8.
On both strategies, I have Start behavior set to "Immediately submit".
When enabling the strategies, the conditions are such that both strategies should enter their own short positions.

Both strategies have code that will print when the entry conditions are met.
I can see the entry conditions are met on both strategies, but only the first one that I Enable will trigger an order.

Psuedo code, similar in both strategies:
If (entry conditions are met)
{
Print("Enter Short " + Time[0].ToString());
EnterShort(Convert.ToInt32(PosSize), "");
}

Review the Output window for Strategy 1 (the first strategy I enable):
Enter Short 11:28:27
Enabling NinjaScript strategy 'Strat1/106813811' : On starting a real-time strategy - StartBehavior=ImmediatelySubmit EntryHandling=All entries EntriesPerDirection=2 StopTargetHandling=By strategy position ErrorHandling=Stop strategy, cancel orders, close positions ExitOnSessionClose=False SetOrderQuantityBy=Strategy ConnectionLossHandling=Recalculate DisconnectDelaySeconds=10 CancelEntriesOnStrategyDisable=False CancelExitsOnStrategyDisable=False Calculate=On each tick IsUnmanaged=False MaxRestarts=4 in 5 minutes

NinjaScript strategy 'Strat1/xxxxxxxxx' submitting order


When I enable strategy 2, I get the exact same text in the output window, except it does contain the "submitting order" output.

The result on the Strategies tab in the Control Center is:
Strategy 1: Position: 100s, Account Position, 100s
Strategy 2: Position: 300s, Account Position, 100s

The result I'm trying to achieve is Account Position 400s; both strategies submit their own orders.

I've read many threads on this and seems like the answers vary widely. Any suggestions are appreciated.

Hello DividedSky,

It looks like the second strategy is in a historical position, meaning had you started the strategy earlier, it would have taken a position.

If you place the following under OnBarUpdate within strategy 2’s code,

if(State ==State.Historical) return;

Does the second strategy put you were you expect?

I look forward to your reply.

It seems to be working with a quick test! thank you!

I need to test it more and will let you know of i have any more questions. (can't test today because of work).

Thanks!

While this is working, it leaves me wondering why it is necessary.
Both strategies are in historical positions. Both strategies are set to Immediately submit.
No matter what order I turn them on, only the first one submits an order... if I'm not using the workaround provided, if(State ==State.Historical) return;
Position = Flat
Turn on Strat2, it submits an order.
Turn on Strat1, it prints that my entry criteria is met, but does not submit.

Flatten, retest in opposite order.
Turn on Strat1, it submits order. Strat2 does not.

I thought the whole point of "Immediately Submit" is that it will join a historical trade if necessary.
I can't justify in my head why ignoring Historical would fix this or why it is necessary. Thoughts?
