|Had something interesting happen with SSE. All in one trade tool showed one issue (example, XXXX) on the two header lines (black field, with blue beneath), but the level 2 quotes belonged to a second (YYYY).|
I saw the great asking price for XXXX, selected my trading venue (NSDQ) and number of shares, and didn't even look at the trade verification window (and thus don't know if it was correctly telling me that I was buying YYYY, not XXXX) while hitting buy button.
Bought wrong issue. Worse, didn't take a photo of the all-in-one window before looking at different quotes.
I noticed this issue once previously, maybe 1-2 months back, but caught it. Keep an eye.
