I'm still grappling with this in my head. Let me see if I understand everything via use of a example (I also want to better understand the quirky issues with using CTS' OCOs/bracket orders via their regular connection - that are avoided when a trader uses the low-cost CTS connection) via a series of questions. When I use the expression "regular connection" I mean if I am NOT using the low-cost connection and I have to deal with these issues with CTS' servers: https://www.sierrachart.com/index.php?page=doc/CTS_T4.php#CTSServerSideOCOBracketBehavior. The ES is trading at 2728.00. I want to buy a 10-lot if it goes lower to 2727.00. So I place a buy limit order at 2727.00. If I get filled on that 2727.00 buy limit, I want an OCO to have a profit target selling 10 at 2929.00 and a sell stop selling 10 at 2725.00. It's a traditional parent and two child order. I have not yet been filled on the parent order. Questions: 1a. If I'm on either the low cost connection or the regular connection the parent buy limit at 2727.00 goes through to the exchange, correct? 1b. If I'm on the low cost connection, whose servers do the two child orders sit while I am waiting for a fill? 1b. If I'm on the regular connection, the two child orders sit on CTS servers, correct? The market goes lower to 2727.00 but only briefly before ticking higher. I only get filled on 7 of the 10 contracts. Questions: 2a. Three contracts are left live on the exchange, correct? 2b. If I'm on the low cost connection, an OCO gets created to sell 7 contracts for a profit and sell 7 for a loss, correct? 2c. On whose server (low cost connection) does this sell 7 profit and sell 7 stop-loss now exist? Sierra's or CTS'? A minute later the market ticks back lower and I get a fill on my remaining 3 contracts. Questions: 3a. On the low-cost connection, is a new OCO created to sell 3 for a profit and 3 for a loss? Or does the pre-existing quantity of selling 7 for a profit/loss get changed? In other words, does one OCO still exist or is it two? 3b. On the low-cost connection does the amended (or second) OCO exist on SC servers or CTS servers? 3b. On the regular connection, it is not possible to amend the sell 7 OCO quantity after getting a partial fill on the parent order, so you end up being long 10 contracts with mismatched profit/stop-loss quantity of only 7 contracts. Is that correct?
