[Question] How to set up OCA orders?

[moritzkork]

Hello,

first of all - thank you for the wonderful work on the ib-api gems, it is a pleasure to work with them, even for a Ruby beginner like me!

• I have successfully set up my stack to configure, build, place, modify / cancel orders + listen to execution data & order states.

I am struggling with setting up OCA (One-Cancels-Another order groups) for my positions and would appreciate code examples

• I've placed an OCA order in TWS manually, (sample order for apple:one LMT SELL order 50% above current price, one STP 80% below), then tried to look up the order through the console / byebug

• the order does show up via (IB::Gateway.current.client.orders), but only the first of the OCA group (the LMT order), the STP Limit is missing... :

(byebug) `client.orders`

• from this order above, I assumed it would suffice to just set :oca_group (unique String) and :oca_type (either 1 , 2 or 3)(https://interactivebrokers.github.io/tws-api/classIBApi_1_1Order.html#a3485999c42d64f3c879ec4a424bab697)
  with the two separate LMT SELL and STP orders, but I get an alert:

IB Alert:: TWS Error 201: Order rejected - reason:OCA handling method mismatch

• I am guessing I should be placing these two orders together ? Possibly passing them an array, together with the :oca:group identifier and the :oca_type ?

I appreciate any help - and I'd be happy to write something up for the documentation after this is solved!

Thank you!
