Tape Tracker: Who Controls the Tape?
Contested — the Tape Score reads 49/100, where 100 is full bull control and 0 is full bear control of the last 10 sessions. This measures control, not condition or forecast: four equal-weight dimensions of direct tape evidence — session control, breadth, pressure prints, volatility — each mapped between documented bounds by one pure function. The identical function replays the 2010+ history, so the live gauge and the band base rates below cannot drift.

The score through time — every session since 2010
3,958 sessions of the same fixed-bound function — no re-fitting, so a 44 in 2011 means what a 44 means today. SPY rides the top pane for context; the score is green while bulls hold the majority of the tape (50+) and red when bears do. The band extremes are rare by construction and carry the study's information.
Tape Score, daily since 2010-10-15 (3,958 sessions). Band edges are fixed at 70/58/42/30 — bulls in control above 70, bears in control below 30. Endpoint: 49/100 (contested).
Which dimension flipped first — the last 60 sessions
The composite hides sequence: breadth can roll over weeks before session control follows, and volatility usually confirms last. Each row is one dimension's daily score on the same five-band scale as the gauge above — read left to right to see who led the current state and who is still holding out.
The four dimensions — every input, with its past year
Each input maps linearly between documented bounds (and is clamped), so 50 always means a normal, two-sided tape. The dashed lines mark the bounds — green where the input earns full bull credit, red full bear credit. Every input links to its own tool with the full series. At least 3 of 4 dimensions must be live to publish a score.

What happened next — SPY after each band
Average SPY return (and share of positive outcomes) after every prior session in each band, 2010+. The extremes are contrarian: bear-controlled tapes preceded the best forward returns — stretched rubber bands, not trend confirmation.

How Tape Tracker Works
- 1Four dimensions of direct tape evidenceSession control sums every 5-minute candle body in ES and NQ futures over the trailing 10 sessions — who actually won the intraday work. Breadth reads the share of ~5,500 stocks above their 10-day average, the McClellan Oscillator and the 10-session net-advances ratio. Pressure prints net surge vs washout prints for each of four feeds ($TICK, $TIKQ, $ADD, $ADQD), equal-weighted so a quiet feed reads neutral rather than letting the busiest feed dominate. Volatility checks whether the VIX term structure and the 10-session VIX change confirm or dispute the other three.
- 2Fixed linear mappings — no fitting, no percentile lookupsEach input maps linearly between documented bounds and is clamped: ES/NQ bull share 42→58%, sessions won 2→8 of 10, breadth 20→80% above the 10-day, McClellan ±80, net advances ±30%, print balance ±100%, VIX/VIX3M 1.05→0.80, VIX change +30→−30%. A score of 50 always means a normal, two-sided tape. Inputs average into their dimension; the dimensions average, equal-weight, into the score.
- 3Fixed band edges: 70 / 58 / 42 / 30Bulls in control (70+), bulls leaning (58+), contested (42+), bears leaning (30+), bears in control (below 30). The edges never re-fit, so a band means the same thing in 2011 and today. At least 3 of the 4 dimensions must be live to publish a score at all.
- 4Backtested by the identical functionThe same pure function replays the full 2010+ history, so the live gauge and the backtest cannot drift. Average SPY returns over the next 5, 10 and 21 sessions are published for every band — and the honest finding is contrarian at the extremes: bear-controlled tapes preceded the best forward returns.
