Function: settleMakerFill(CollateralManager self, SettleMakerFillParams params)

This internal function performs maker-side accounting of margin and debt during the matching process after their limit order is partially or fully filled by a taker and calculates the collateralDelta to credit an account.

Inputs

• params.account

  • Control: from matchedOrder.maker.

  • Constraints: N/A.

  • Impact: the address of the maker account.

• params.subaccount

  • Control: from matchedOrder.subaccount.

  • Constraints: N/A.

  • Impact: subaccount.

• params.marginDelta

  • Control: the result of market.processMakerFill function execution + fundingPaymentResult.marginDelta.

  • Constraints: N/A.

  • Impact: marginAccount.margin data of the provided account and subaccount will be updated by the marginDelta.

• params.collateralDelta

  • Control: the result of market.processMakerFill function execution - quoteAmountTraded (in the case of !reduceOnly and decreasing trade).

  • Constraints: N/A.

  • Impact: if less than zero, account will be credited by collateralDelta.

• params.debt

  • Control: the result of market.processMakerFill function execution + fundingPaymentResult.debt

  • Constraints: N/A.

  • Impact: marginAccount.debt data of the provided account and subaccount will be updated by the debt and makerFee.

• params.makerFee

  • Control: the result of getClearingHouse().getMakerFee(matchedOwner, matchData.quoteDelta) function execution.

  • Constraints: N/A.

  • Impact: marginAccount.debt data of the provided account and subaccount will be updated by the debt and makerFee.

• params.close

  • Control: set up if subaccount was fully closed.

  • Constraints: N/A.

  • Impact: if true, collateralDelta is increased by debt.
