Position reconciliation
Telling the Play's quantity from everything else in your account.
Lighter positions are net per market. If you already held NVDA, an account showing more NVDA after a Play does not tell you how much of it the Play owns. So PLAYS records a baseline of your position before any order and compares:
expected account = baseline + the Play's own fills actual account = what Lighter reports now
| Result | Meaning |
|---|---|
| MATCHED | The account equals baseline plus the Play's fills |
| EXTERNAL REDUCTION / INCREASE / CLOSE | Quantity changed outside PLAYS |
| POSITION REVERSED | The position flipped side |
| ATTRIBUTION AMBIGUOUS | It changed and a prior position makes the owner undeterminable. PLAYS says so instead of guessing |
| VENUE STATE UNKNOWN | Lighter could not be read or the data was stale |
