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

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.
There is a solution to this:
Attached Orders: Automatic Replacement Market Order for Rejected Stop Attached Order

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.
We were not aware of this. Not sure why that would be the case. Is there any order rejection when you modify the order?

Also the ultimate solution to the above problems is for us not to use LMAX accounts directly and use an omnibus account and maintain positions and balances independently. Longer term we do forsee that happening. Probably the account would be through AMP and you can trade futures and Forex all-in-one using a common account balance. This capability is expected to come later in the year.
