Tape pinned near flat into the 2 PM FOMC decision, with breadth modestly positive and tech leading. — Midday action is quiet and rangebound as the major index proxies hover right around VWAP ahead of this afternoon's Fed rate decision; breadth on our watchlist skews positive and technology is the strongest group, led by semiconductor and AI-infrastructure-adjacent names.

The read

Index structure, breadth, and sector leadership at the time of the scan.

Index Structure (SPY / QQQ)

SPY is trading just below both its intraday VWAP ($759.57 vs $759.92) and its ~20-bar 5-min moving average ($760.22), a mildly cautious read, while QQQ is essentially pinned right at VWAP ($709.69 vs $709.66) but also below its 20-bar MA -- both indexes look like they're consolidating rather than trending ahead of the Fed.

Breadth (watchlist proxy)

126 of 186 non-index-proxy watchlist names (excluding SPY/QQQ/DIA/IWM) are green midday, a broadly positive tilt -- this is a watchlist proxy, not a true exchange-wide advance/decline line.

Sector Leader

Technology is today's leading group on the watchlist (+1.78% average change), driven by strength in semiconductor, datacom, and AI-infrastructure-adjacent names like CIFR, AXTI, LITE, CRDO, and ALAB, while energy names are the weakest group (-2.19% average).

Catalyst Watch (1–3:30 PM ET)

The FOMC rate decision is due at 2:00 PM ET with Chair Warsh's press conference at 2:30 PM ET, sitting squarely in this afternoon's window and likely to dominate price action from here.

Afternoon candidates

Nothing met the bar for a clean afternoon setup today.

The scan ran but found no setup it considered genuinely notable — that's a normal, honest outcome, not a bug.

What this is (and isn't)

A third, independent lens on the same watchlist, this one framed around a classic day-trader's midday checklist.

Every weekday around 1:00 PM ET — the "lunch lull" — a separate job re-reads the same maintained watchlist for signs of an afternoon setup: index structure relative to VWAP and short moving averages, whether breadth (approximated across our own watchlist, not the full market) is expanding or deteriorating, which sector is showing real relative strength, and any scheduled catalysts between 1:00 and 3:30 PM ET.

This job never places trades — it has no access to cash, holdings, or the trade ledger
Breadth and sector-leadership figures are proxies from our maintained watchlist, not a full-market feed
Ideas here are commentary, not positions in the paper portfolio
It's fine, and common, for it to flag nothing at all on a quiet day

Execution & risk protocol

The standing rules any flagged setup is judged against — not simulation rules, just the discipline this checklist is built on.

Entry window: breakout confirmation between 1:30 and 2:30 PM ET, when institutional volume typically returns
Stop-loss: just below the consolidation low, or slightly below intraday VWAP
Hard exit: scale out or close by 3:45–3:50 PM ET, ahead of closing-auction volatility
