# Open Interest (OI) Points

Key characteristics:

* Points are linked to open position size and holding duration
* Daily OI Points are calculated based on the aggregate of all positions opened during the day
* Larger position size and longer position holding time generally leads to higher OI contribution

Anti-Farming Mechanisms for OI Points

To ensure the integrity and fairness of the Open Interest (OI) Points system, Astros applies a set of anti-farming rules designed to discourage short-term, low-quality position manipulation.

These rules are implemented through a combination of on-chain enforcement and off-chain monitoring, and may be adjusted over time as the system evolves.

**Minimum Effective Position Size**

* Only positions with a notional value of at least 10 USDC are considered valid for OI Points
* Positions below this threshold do not generate OI Points

**Minimum Holding Duration**

* Positions must be held for a minimum of 3 minutes to be eligible for OI Points

Positions closed before this duration do not generate OI Points\
**Per-Wallet Frequency Limit**

* Each wallet is limited to a maximum of 10 effective position openings per hour
* Any additional openings beyond this limit may be temporarily excluded from OI Point calculations

**Liquidation Penalty**

* If a position is liquidated, the OI Points associated with that position are penalized
* Liquidated positions may receive:
* A reduced OI score (e.g. a partial multiplier), or
