Quick answers

What does Directional Flow measure?

Two things per instrument: how strong the price trend currently is (measured over the past year, with recent days weighted more heavily), and how that strength has CHANGED over the past 5, 21 and 63 trading days. The change is the point — trend strength usually turns before price does, so a stock still rising while its trend strength fades, or still falling while its trend strength builds, is flagged before the price move shows it.

How often does Directional Flow update?

Once per US trading day, after the close (the scan runs at 23:05 UTC; the page shows the new reading roughly half an hour later). Around 250 instruments are scanned each run: US headline indices, the 11 sector funds, country ETFs, tech thematics, the Closelook indices and all of their constituents.

What do "Long warning" and "Early chance" mean on this page?

They are the two in-between states of the four-state flow grammar. "Long warning" = an instrument that was hot but is losing trend strength — the kind of setup that often precedes a top. "Early chance" = an instrument that was cold but whose trend strength is turning up — the kind that often precedes a base. Both are watch-list labels in a research diary, not trade recommendations.
