sweeps
One order. Not thirty rows.
A sweep doesn't land in one print — it tears across exchanges over hundreds of milliseconds, and most tools hand you the pieces. optionHack tracks it while it fills and alerts the moment the last print lands with the whole thing tallied: every exchange, every fill, one order. A 4,000-lot reads as 4,000 — not forty prints of 100.
spreads
Named. Not just “complex”.
Most tools lump every multi-leg print into one bucket with a single switch to hide it — which also hides the readable trades. optionHack identifies two-leg packages by structure and labels them for what they are. Keep the clean spreads, drop the ragged multi-leg rest — they are two different things.
greeks
Priced at the print. Not the close.
The underlying streams alongside the options tape, so IV and the Greeks are solved against the stock price at the instant of the trade. Delta says whether 50,000 contracts is a lottery ticket or stock exposure in disguise. Hedge impact converts it into the shares a market maker has to trade to stay neutral.
short interest
The HSI tag. FINRA, on the alert.
HSI — high short interest. FINRA's twice-monthly figure, ranked by days to cover: shares short against average daily volume, roughly how long the position would take to buy back — the number that makes a squeeze. Set your own threshold; every name at or above it lives in the widget, and when one of them prints, the alert wears the orange HSI tag — days to cover and percent outstanding, right on the row. Same number decides both — the widget and the tag can never disagree.
dark pool
The block behind the flow.
Roughly half of US equity volume never touches a lit exchange. optionHack streams the off-exchange tape alongside the options feed and surfaces the large blocks — then ties them together. When a call sweep fires in a name that just had a $40M block cross, the alert says so. Both happened in the same name four minutes apart, and that is the part worth seeing.
widgets
The Widget Rail w/ powerful tools.
The feed is what the tape is doing right now. The rail is what it has been doing all day — a column of widgets, each answering one question, each drawn from the same data the alerts are built from, so the rail and the feed can never tell you two different stories.
bullish call/put
The most call-heavy names on today's tape — every print counted, not a sample.
bearish put/call
The most put-heavy, the same count read the other way.
short interest
FINRA's list ranked by days to cover. Your threshold builds it — and stamps the HSI tag.

the field
