About CSTL

CSTL (Castle Biosciences, Inc. - Common stock) trades on NASDAQ and is tracked by the PennyStock.Ninja real-time scanner. The scanner monitors CSTL for premarket gaps, unusual relative volume (RVOL), VWAP reclaims and rejections, and vibe signals such as the Surfer breakout, Ninja stealth accumulation, and Fade caution patterns. Watch this name for catalyst-driven setups — earnings, contracts, partnerships, and unusual options flow are the most reliable triggers for a meaningful intraday move.

What to watch on CSTL

RVOLWatch for CSTL trading at 3× or more its average volume — this is the first tell that something is moving. Confirm with price direction before assuming it is bullish; high RVOL on a red candle below VWAP is distribution, not accumulation.

VWAPIf CSTL is holding above VWAP on rising volume, bulls are in control intraday. A clean VWAP reclaim after a morning dip is one of the highest-probability long setups for penny stocks.

Premarket gapA premarket gap on CSTL with an identifiable catalyst (earnings, FDA, contract, partnership) is the most reliable setup. Gaps without news fade more often than they hold.

Float & short interestLow-float names with elevated short interest can squeeze violently. Always check the float and short interest on CSTL before sizing into a momentum trade.

HaltsCSTL can be halted (T1 news pending, T12 information request, or LULD volatility). Wait for the resume print and the first 1-minute candle before re-entering.
