How it works
01 · The promise
The most likely line is the middle of the range: half of outcomes land above it, half below. Nobody trades a single line, so we never sell one.
2 in 10 finished outcomes should land inside the 2 in 10 range.
8 in 10 should land inside the 8 in 10 range. Anyone can draw a narrow fan chart; everything on this page exists to make these counts come true instead.
02 · Data in
Daily settlement prices flow in from real exchanges for the sectors and the index it tracks. No synthetic feeds, no hand-picked histories.
The markets arrive as one panel: the sectors and the index it tracks sit side by side, because what one does often matters to another.
03 · Joint patterns
One sector leans on another, and the index leans on them all. Some pairs barely notice each other. The couplings a desk pays attention to are real, but few.
When one sector jumps, the model lets that jump inform the markets coupled to it the same day, inside the reading and not after it. That is what "joint patterns" buys.
04 · The fan chart
For each day ahead the model answers with a full range of levels around the middle, paired into ranges that hold 2 in 10, 4 in 10, 6 in 10, 8 in 10 outcomes.
Matching levels bracket a range with a counted share inside. Each day ahead gets its own column, and further out the columns stand taller: less is known, and the picture says so.
Connect each range’s edges day by day and the deliverable appears: a fan chart of possible futures.
