The old GMX V2 contracts have been disabled this week For the new GMX V2 contracts, please note that the execution fee calculation has been updated to allow for it to more closely match the actual transaction cost Instead of ESTIMATED_GAS_FEE_BASE_AMOUNT, the calculation now uses ESTIMATED_GAS_FEE_BASE_AMOUNT_V2_1 + ESTIMATED_GAS_FEE_PER_ORACLE_PRICE * oraclePriceCount Full implementation details: https://github.com/gmx-io/gmx-synthetics/blob/main/contracts/gas/GasUtils.sol#L287
