What is open interest???

**Open interest** is a measure used in financial markets, especially in futures and options contracts, to indicate the total number of open contracts that have not yet been settled. Here are some key points about open interest:

1. **Definition**: It represents the total number of futures or options contracts that are active and have not been closed or settled. Each contract has a buyer and a seller, and open interest is calculated by adding all open contracts and subtracting closed contracts - Economipedia](https://economipedia.com/definiciones/interes-abierto-open-interest.html).

2. **Indicator of Activity**: An increase in open interest generally indicates that there is more activity in the market, as more participants are opening new positions. Conversely, a decrease in open interest may suggest that participants are closing their positions - Economipedia](https://economipedia.com/definiciones/interes-abierto-open-interest.html).

3. **Trend Confirmation**: Analysts use open interest to confirm the strength of a trend. An increase in open interest along with an increase in prices may indicate a strong bullish trend, while a decrease in open interest may suggest that the trend is losing strength - Economipedia](https://economipedia.com/definiciones/interes-abierto-open-interest.html).

4. **Data Publication**: Open interest data is published at the end of each trading day. Additionally, reports such as the "Commitment of Traders" from the CFTC provide details on open interest in the U.S. market.
