Multi strategies with opposite oreders on the same instrument

[gjing]

If I apply two strategies, strategy1.cs and strategy2.cs, on the same instrument, like ES, and the strategy1.cs already opened a long position, what will happen if the strategy2.cs opens a short one later? Will it close the first long position or open a new short one?

I'm using IB as my broker.

Thanks in advance,
Gary

Hi Gary,

Strategies run independent from each other and are not aware of the actual account position.

In the example provided, your account position will be flat, while strategy 1 is long and strategy 2 is short. More information on this is available here:
