A. Opening a position in CoastDAO, depositing collateral to generate CUSD, and creating an order in the specified trading strategy contract (providing the trading pair and trading strategy as bytes32

function openLockGemAndDrawAndCreateOrder(
    address gemJoin,
    bytes32 ilk,
    uint amtC,
    uint wadD,
    bytes32 strategyName,
    uint8 strategyId
)

  gemJoin:The contract addresses of these collateral assets in CoastDAO (there are as many addresses as there are collateral assets).
 ilk：Collateral type
 amtC：Amount of collateral
 wadD：Amount of cusd
 strategyName Name of the trading pair
 strategyId  Trading strategy Id (1,2,3,4)

b. Opening a position in CoastDAO, depositing collateral to generate CUSD, and creating an order in the specified trading strategy contract (providing the trading pair address)

function openLockGemAndDrawAndCreateOrderByPair{

    uint256 amtC,
    uint256 wadD,
    address strategyPair
}
