Insider Flow
Form 4s, from EDGAR
The insider trades that actually move markets.
Form 4s straight from EDGAR, read every 2 hours in the day for the S&P 500 and nightly for the rest, with grants and gifts set aside and clusters of buying flagged.

From every Form 4 to the trades worth reading.
Most Form 4s are routine. Convexity keeps each filing, scores each trade by what it is, and looks for buying that bunches up.

EDGAR
Form 4 XML from EDGAR, every 2 hours from 06:00 to 20:00 UTC for the S&P 500, and nightly for the rest.
- 02
Codes
Each trade keeps its transaction code. Awards, gifts and trades under $1,000 score zero and stay out of every list.
- 03
10b5-1 plans
The plan box, or a footnote naming the rule, marks a planned trade. The alt-data clusters drop those; the tape still lists them.
- 04
Clusters
The tape flags three or more buys in a name inside 10 days, four or more sales, and trades over $5 million.
Scheduled liquidity vs. discretionary conviction.
A sale under a 10b5-1 plan was set up months before it happened, so it says little about what the insider thinks today.
An open-market buy has no plan behind it. Purchases score highest, a C-suite buyer higher still, and buys that bunch up are the ones the clusters find.
Every code kept, the routine set aside.
Each trade keeps the code its filing gives it, and the code decides how it scores.
POpen-market purchaseThe strongest score, raised for a C-suite buyer and for size.
SOpen-market saleScored below a purchase, raised at $5 million.
MOption exerciseKept and scored low, and left out of the clusters and the tape’s table.
FTax withholdingKept and scored low, and left out of the clusters and the tape’s table.
A G J K WAwards, gifts, otherScored zero and kept out of every list, as is any trade under $1,000.
Each code’s score for a trade of $50,000 or more, to scale; the outline is what a C-suite buyer and size can add. A kept trade under $50,000 scores as low as F.
