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 Fee is recorded at position opening based on the deviation between your execution price and the oracle price

• The fee is charged when you close your position, irrespective of whether you are in profit or loss

• It is deducted from your available margin upon closing

• It affects your effective PnL in all scenarios

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 -$20 ($30 - $50)

• If you close with $100 loss → you lose $150 ($100 loss + $50 Price Impact)
