Hello, I am developing my own ATS which is about 80% done, however, in the current setup for each entry order my Strategies Execution System also (immediately) generates closing Stop Limit and take profit orders. If I do not want such scenario then which system should generate closing orders? at the present Strategies Execution System is not aware of open orders and Order Management System does not get the quotes data. If you have experience with ATS what is the way to implement order closing? Here is the scheme, each system is in it's own executable, they communicate through messaging. Broker's Quotes Server -> (quotes) -> [ Quotes Connector -> (quotes) -> Strategies Execution System -> (order signals) -> Order Management System <-> (order signals) <-> Order Routing System (FIX Engine) ] <-> (order in FIX format) <-> Broker's FIX Server Thank you in advance.
