Post From: Glitch with SC Order Routing Service

I experienced a glitch with the SC Order Routing service today at about 15:40 ET. I confirmed with my broker that I'm now flat and have no working orders, so this is just for reporting the issue to you.

I was long one ES contract and tried to scale in with a limit order. I got filled, but my position was then reported in the DOM as long 2 contracts at a price well above where either of the two contracts filled/should have filled. I got this message in the trade service log:

Notice - An overfill UpdateOrder call has occurred. Overfill Quantity: 1. Total filled quantity: 1. Order quantity: 1 | Symbol: ESM20_FUT_CME | TradeAccount: ACxxx | InternalOrderID: 1087 | ServiceOrderID: 671294 | Current Status: Filled | 2020-03-23 15:39:21.933 *

The scale-in limit order still appeared on the DOM (status was something like pending acknowledgement) and couldn't be directly cancelled.

I hit some combination of "Cancel All" and "Flatten" - the position may have stopped out on it's own, though, it was a bit of a blur. The DOM reported my position as flat. I entered a few more orders, which filled as expected.

Right now, I still show as flat in the DOM but the Trade Activity Log is off on the system where I was trading. The statistics tab shows an odd number of contracts filled, and the trades tab shows a max open quantity as off by one from the time of the glitch (an 8 contract trade shows as max open of 9). The trades tab shows an open short position of qty 1.

Opening the Trade Activity Log on a second system, which had been disconnected the entire session, seems to show correct data. The DOM on the second system also shows a different daily PnL than the first.
