Post From: LMAX orders through web app can't be modified by SC (and attached orders consuming margin)

I understand there is an issue with FIX orders to LMAX, where attached orders (once the parent is filled and they become active) are not recognized by LMAX as attached orders, but as new parent orders. This creates multiple issues such as: 1) Effective leverage is heavily reduced (from 1:30 to 1:7 maybe depending on number of orders/fills). If you have multiple orders waiting to fill you basically have to cancel them and manage the first filled parent. 2) Security: As LMAX deals with the attached orders as if they are new ones, there have been many times where the parent fills, the Stop Loss attached order gets rejected due to leverage restrictions (which would not happen if it were seen as attached) and I have to scramble to edit the stop-loss order via their website. 3) security v2: the worst part of all maybe, is that the stop orders that are inputted through the LMAX web interface ARE NOT manageable by Sierra Chart! I cannot move a stop (or limit) order I see on the chart, as it was entered through tie LMAX web interface. I cannot even cancel these orders through SC. I understand that this is possibly some kind of limitation or implementation of the FIX protocol. The question I have is: can something be done about it? Can you yourselves improve on this situation? Can LMAX work on their end to fix this issue? Can you work on this together? Please let me know, thank you. |
