What the research found
Measuring Selling Pressure (2013-09-10) discloses a six-component SP-500 selling-pressure diffusion, a numeric 4% peak-to-trough correction trigger, BUY when diffusion rises above 4 then falls below 4, and sell warnings on 0->1 and 1->2.
Relative strength, ROC, down-day/double-down/large-down windows and cutoffs remain chart-only; labeled 21-day proxies and a nearby parameter grid were used without claiming source parity.
Subscriber chart 5-minute cadence and native diffusion series are absent from the checked-in snapshot (zero linked assets).
15 labeled public-proxy variants executed on ^GSPC/SPY/IEF/^VIX; exploratory inferred reconstructions only.
Best tested causal Sharpe: spi-breadth-advisory-gate-lag1-gspc (0.8184869945314879).
Disposition is exploratory_tested_proxy with explicit no-go for playable Other/Indicators fidelity promotion.
Mechanism and falsifiers

Not recorded in this iteration.
Confidence and limitations
No native Selling Pressure component or diffusion series in checked-in snapshot.
Six component rolling windows and prevalence thresholds are labeled inferred proxies.
Breadth advisory +1 uses Great Trough/Zweig workbook markers, not live chart integration.
Exact 5-minute subscriber refresh cadence cannot be reproduced from daily closes.

Measuring Selling Pressure for Market Entry Timing | RecessionAlert
What the source claims
Six price-action components form a Selling Pressure Diffusion; BUY when diffusion rises above 4 then falls below 4; sell warnings on 0->1 and optional 1->2.
Percentage correction threshold is disclosed as 4% from a prior peak; relative strength, ROC, and prevalence windows/cutoffs remain chart-only.
15 labeled public-proxy variants on ^GSPC/SPY/IEF/^VIX without native Selling Pressure series.
Rules actually disclosed
Six price-action components form a Selling Pressure Diffusion; BUY when diffusion rises above 4 then falls below 4; sell warnings on 0->1 and optional 1->2.
Percentage correction threshold is disclosed as 4% from a prior peak; relative strength, ROC, and prevalence windows/cutoffs remain chart-only.
What had to be inferred
15 labeled public-proxy variants on ^GSPC/SPY/IEF/^VIX without native Selling Pressure series.
Research questions
Can disclosed six-component Selling Pressure diffusion rules be tested with SPY/^GSPC/^VIX proxies when native RA series are absent?
