Required Methods

fn save_oracle_price_samples_sync( &self, samples: &[NewOraclePriceSampleInput], ) -> Result<()>

Persist a batch of price samples for a given symbol/expiry. Duplicate samples (by symbol, expiry, timestamp, source) are silently ignored.

fn save_oracle_settlement_price_sync( &self, settlement: &NewOracleSettlementPriceInput, ) -> Result<()>

Persist a finalized settlement price. If a settlement already exists for this (symbol, expiry), it is silently ignored.

fn get_oracle_settlement_price_sync( &self, symbol: &str, expiry_timestamp: i64, ) -> Result<Option<f64>>

Load a settlement price from the database. Returns None if no settlement exists for this symbol/expiry.
