Post From: When using OCO Orders via API, Initial Order gets split into two orders

Hi guys,

I am trying to use Sierras DOM to trade SPY via IB (Brokerage).

The issue I am having is when I use even a simple 2 Bracket Attached Order to split up Target 1 (OCO Group 1) and Target 2 (OCO Group 2 (with Stop 1 and Stop 2 being the same price) it sends 2 Separate Buy To Open Orders splitting the quantity.

For example, I want to trade 100 shares, and split up 50 Shares as T1/S1 and 50 Shares as T2/S2. When I submit the initial order- for an example of Going Long that 100 Shares- it adds two orders (with 2 commissions) of 50 Shares each rather than filling my 100- and then adding the Attached Orders (OCO 1 and OCO 2)

Is there a way to make sure my Buy To Open order is for my full position size of 100 - and NOT the size of my individual targets (50+50)
