The Data Behind the Trade
Nydar's WSB Trading Floor is an alternative data dashboard with 16 widgets covering 8 data sources that institutional terminals typically charge $2,000+/month to access: Reddit mention velocity across 4 subreddits, dark pool volume from FINRA ATS data (40-45% of all US equity volume trades off-exchange), short interest with days-to-cover calculations, congressional trades under the STOCK Act, SEC failure-to-deliver reports, insider cluster detection, gamma exposure (GEX) with flip-point mapping, and options max pain. Research by Cookson, Engelberg, and Mullins (Journal of Finance, 2023) found that social media disagreement predicts 35% higher next-day trading volume and wider bid-ask spreads — Nydar makes these signals visible in real time.
What You Can Do With This
Trade What They Trade
Congress members, corporate insiders, and activist investors all file their trades publicly. Nydar aggregates these filings and surfaces the patterns.
Spot Squeeze Setups
High short interest, spiking borrow fees, rising FTDs, and Reddit going nuts on the same ticker? That's your checklist.
Don't Get Blindsided
Fed liquidity dropping, FOMC tomorrow, and your stock just had an ATM offering? Better to know before the candle prints.
Mention velocity — tracking which tickers are accelerating across Reddit in real time
How Reddit Sentiment Works
Nydar does not just count mentions. Here is the pipeline from raw Reddit post to actionable signal on the dashboard.
Subreddits Scraped
r/wallstreetbets, r/stocks, r/options, and r/investing — scanned continuously for ticker mentions
Mentions Extracted
Ticker symbols parsed from post titles, body text, and comments. Duplicates and bots filtered out
Velocity Calculated
24-hour acceleration rate — how fast mentions are growing compared to the prior period
Sentiment Scored
Each mention tagged as bullish, bearish, or neutral based on context. Aggregated into a net sentiment score
What the Numbers Mean
Every metric on the WSB Trading Floor has a specific definition. No ambiguity.
Mention Velocity
The percentage change in ticker mentions compared to the prior 24-hour period. A stock going from 50 to 200 mentions = +300% velocity.
Sentiment Score
Net ratio of bullish to bearish mentions. Ranges from -100 (all bearish) to +100 (all bullish). Zero means evenly split or neutral.
Context-aware — "buying puts" registers as bearish even though it mentions buying.
Dark Pool Volume
Weekly off-exchange trading volume reported by FINRA ATS. Expressed as a percentage of total volume. Spikes above the 20-day average flag unusual institutional activity.
Updated weekly from FINRA ATS data. Unusual = >1.5x average volume ratio. Approximately 40-45% of all US equity volume executes off-exchange as of 2025 (FINRA).
Short Interest (SI% of Float)
Shares sold short as a percentage of the free float. 20%+ is considered high. Combined with days to cover and borrow fees, it forms the core squeeze signal.
Days to cover = shares short / avg daily volume. Higher = harder for shorts to exit quickly.
Failure to Deliver (FTD)
Shares that were sold but not delivered within the settlement period. Reported daily by the SEC. A spike ratio above 3x normal flags potential forced buying pressure.
Measured as spike ratio = today's FTDs / 20-day average FTDs.
Gamma Exposure (GEX)
The net gamma that market makers need to hedge across all strikes. Positive GEX = market makers buy dips and sell rips (suppresses volatility). Negative GEX = they amplify moves in both directions.
The gamma flip point is the strike where GEX changes sign — a key level for directional traders.
