QQQ started the week at $723.05 with +$3.7B of gamma exposure (GEX), a call wall at $730, and a second wall at $735 sitting five points behind it. The interesting part of Monday’s map was not the level. It was that the level was already crowded, already stable, and already 16 points above the line that would have changed the regime.

Net GEX came in at +$3.70B against +$3.66B on Sunday — a $40M change, +1.1%. Call GEX was unchanged at $11.4B, put GEX unchanged at -$7.7B, total GEX unchanged at $19.1B. The call wall stayed $730 and the put wall stayed $660. The only figure that actually moved was zero gamma, from $706.23 to $707.18, and even that was a 95-cent drift.
A stable map is not a boring map. It means the open interest that dealer hedging has to work against did not get rebuilt overnight, so the levels it implies are the same levels that were there yesterday. That is the condition under which those levels are worth trading.
Every value above comes from one feed (live GEX) so the strikes are comparable. The $730 reading on the InsiderFinance panel was +$799.7M net at the same moment — a different feed, not a correction.

The live-GEX feed put roughly $857M at $730 and $655M at $735. That is the detail worth sitting with: this was not one isolated wall with clear air behind it. Between $725 and $735 there were five positive strikes stacked in a row, and the two heaviest were separated by five points.
The practical read is that a controlled move into $730 can pinning, while sustained acceptance through it opens a path to $735 — where another large hedging concentration is waiting to slow price down again. First touch favors the fade. Acceptance favors the next rung.
This is the highest-confidence strike-level call/put split in the whole session — the only strike where the panel exposed both sides.

The panel exposed the call/put split at $730 and nowhere else: +$954.0M of call gamma against -$154.3M of put gamma for +$799.7M net. Two things follow. First, the wall is genuinely call-dominated — this is not a mixed strike that happens to net positive. Second, versus Friday and Sunday’s visible net of about +$799.9M, the new reading of +$799.7M is a $0.2M change. That is a wall holding its shape, not one decaying into a breakout.
The morning plan separated by capital and by risk, and it is worth reading in that order because the least exciting leg is the one that mattered by Thursday.
Reuters had the S&P 500 up about 5.8% over four sessions with unusually strong short-dated call demand and FOMO-type positioning. That combination does something specific to a positive-gamma map: it keeps the dampening effect intact while raising the odds of opening exhaustion and sharp rotations.
Macro was already on the board: July PPI on Thursday Aug 13 at 8:30 ET inside a broader Aug 12-14 inflation window, and NVIDIA’s fiscal Q2 on Aug 26 sitting inside any 30- or 45-DTE expiration opened that day. Entry delta alone could not judge a 14-DTE position that spanned that cluster.
The aggressive side got taken, and it is worth publishing the fills because they are the honest counterweight to the map being right:
By Tuesday morning that session was summarized as two trades: one made $7,000, one lost $7,000. Pretty flat on the zeros. A doubled contract price and a flat day are not a contradiction — they are what happens when the winning leg is small and the losing leg is the same size.
$730, unchanged from the prior session. The InsiderFinance tooltip decomposed it as +$954.0M call gamma against -$154.3M put gamma for +$799.7M net, and a separate live-GEX feed showed roughly $857M at the same strike.
Because it changes what a breakout can do. With about $857M at $730 and $655M at $735 on the same feed, acceptance through the first wall runs straight into another large hedging concentration five points later — so the first break is more likely to slow than to run.
