Heartflow, Inc. (HTFL)

RSI 14

Momentum gauge, 0–100. A low reading describes losses dominating recent gains; it does not predict a reversal. Recomputed at the what-if price from the served daily tape.

vs 50-day

The average close across 50 sessions. Trading at or below it describes price location versus the recent trend; it is not evidence that buyers will defend the line.

Bollinger

A 20-session volatility envelope. A lower-band pierce describes an unusually low price relative to that recent distribution; it does not guarantee mean reversion. The band re-forms around the what-if price.

VWAP 20

A 20-session rolling VWAP approximated from daily typical price and volume, not an intraday session anchor. Being below it is a price-location descriptor, not a forecast.

Entry level

The entry reference published by the audited level composer from the stock's support zone. It is a model level, not an instruction or guaranteed floor.

Put wall

The strike with the largest put open interest in the stored chain snapshot. It is an options-positioning reference, not verified price support.

MACD

Momentum-shift gauge shown as context, not part of the alignment rule. Recomputed at the what-if price when the served daily tape is usable.

RVol

That session's volume against this name's own average over the last 20 sessions. Above about 1.5x is unusually active for this name and below about 0.7x unusually quiet; heavy volume says a lot of shares changed hands, never which way the next move goes. A hypothetical price cannot create volume, so this tile holds steady as the slider moves.

Short int.

Shares sold short as a percentage of float. The 20% threshold is a crowding descriptor, not a forecast of a squeeze. This value updates on the reporting cadence.

ATR

Average true range describes the stock's recent daily price range. It is informational and does not enter the alignment count.
