FAQ
What is the Directional Flow score?
A number we compute every night. It measures how steady and reliable a price trend is — most scores sit below 100, and only exceptional trends go far above it. A high score means prices have been moving in one clear direction, in an orderly way. It grades the quality of a move, not just its size.
How can a theme have a trend score?
We measure the score on the US-listed ETF that tracks it. That means the score reflects what a US-dollar investor actually experiences — for foreign markets, that includes the currency move as well as the local market.
How often is this ranking updated?
Our engine runs after every US market close. This page is rebuilt every morning with the fresh ranking, and it always shows the date of the scan it was built from.
Is this investment advice?
No. Closelook publishes an investment research diary, not investment advice. The ranking describes what our engine measures in past prices. Past performance may not be an indication of future performance.
