Dark pool flow in $GLD turned net-seller today after yesterday's massive $1.64B accumulation — the largest single-name dark pool position of that session and the biggest gold print in this series.

Today's tape:
10:39 AM → $331.1M SELL
12:01 PM → $123.7M BUY
Net: -$207.4M

Q3 flow pattern:
Aug 5: +$486M
Aug 12: +$228M
Aug 20: -$402M (Treasury buyback day)
Aug 24: +$1.64B
Aug 25: -$207M so far

The timing matters. NVDA earnings drop tomorrow. Jackson Hole starts Thursday. Yesterday's $1.64B gold accumulation looked like pre-event insurance. Today's trim — one day before both catalysts — suggests someone's locking in or rotating out ahead of the Fed and the biggest earnings print of the quarter.

The dark pool loaded gold as a hedge, then started peeling it off before the macro and micro risk events hit. Classic institutional flow: position into uncertainty, trim into the announcement window.

Watching whether this selling accelerates or if it was just a tactical unwind. The data follows the data.
