Price impact fee

Price Impact is an adjustment based on a function of deviation in entry price from actual price reported by pyth oracle feed corresponding to the asset at the instant when you open a position. It accounts for potential latency in landing oracle update transactions and the discrete nature of sampling frequency used in recording the price published by the oracle, preventing misuse of the implicit latency by malicious actors.

Key points:

- Price Impact is only deducted from profits when you close

- It is capped to your profit amount - you can never lose collateral to price impact

- If your position is at a loss, the applicable Price Impact is $0

- It does not affect your liquidation price or margin requirements

Example:

- You open a position with $50 Price Impact recorded

- If you close with $200 profit → you receive $150 ($200 - $50)

- If you close with $30 profit → you receive $0 ($30 - $30, capped)

- If you close with $100 loss → you lose $100 (Price Impact = $0)
