Flagship case / research product
Public beta liveA market reading is only useful when uncertainty is visible too.
Cat Euphoria Index organizes fear, greed, and asymmetry readings for US and BTC/Crypto markets. The public beta shows daily cuts, coverage, and freshness without turning context into investment advice.
Live product interface
cat-euphoria-index.vercel.app
Public surface displaying daily cuts, sentiment readings, asymmetry diagnostics, and traceable components.
The problem
One scale does not explain the whole context.
External sentiment readings are useful, but have their own coverage, cadence, and methodology. The product had to show what composes each cut, when information is absent, and what is still diagnostic only.
Method
From persisted observation to public surface.
- 01
Persists a daily cut
Each reading starts from recorded observations, not an improvised answer in the interface.
- 02
Shows coverage and freshness
The interface makes it clear when a component is available, stale, or outside the selected cut.
- 03
Separates diagnostic readings
Complementary context and research stay out of the primary reading until they meet their own criteria.
- 04
Sets the usage boundary
Each reading makes clear whether it is an index, diagnostic, context, or research, without presenting itself as investment advice.
Principal indices
Four readings, explicit roles.
Fear & Greed US
US MarketAn official daily cut for the US market on a fear-to-greed scale.
Compra/Venda US
US MarketA complementary asymmetry diagnostic for protection/selling and opportunity/buying.

BTC / CryptoA preliminary daily BTC/Crypto cut suited to the market's 24/7 rhythm.
