ChartHorizon — WTI Crude Oil continuous futures chart with volume, open interest, COT hedging program and calendar spread

The real dashboard — continuous price, roll markers, volume, CFTC open interest, COT hedging program and the front–next calendar spread.

One signal, four confirmations

Conviction, not noise.

ChartHorizon only flags a setup when independent signals agree — so you act on alignment, not a single indicator.

The 4/4 conviction system

Commercial COT positioning, seasonality, term structure and FX strength have to line up before a setup counts. The Futures Strength board surfaces only 3/4 and 4/4 alignments — everything weaker is dropped.

Commercial COT

Track what the hedgers are doing each week, straight from the CFTC — public-domain positioning data.

Seasonality

5-, 10-, 20- and 40-year seasonal curves with onset projection — only when four curves agree on direction.

FX strength heatmap

A currency-strength heatmap from −4 to +4 with a policy-rate bias, plus the highest-conviction pairs.

Local-first & private

Runs entirely on your machine over localhost. No cloud, no account — your data never leaves your computer.
