 **NOTE:** When integrating with **Energy Futures Price Feeds**, it is not recommended to rely solely on the first month expiry price feed as there is often lower liquidity towards expiration.
 Best practice is to combine, 1-month, 2-month and 3-month feeds or use the weighted average which is represented by spot price(USOILSPOT or UKOILSPOT).
