Function: updateOpenLimitOrder(uint256 _pairIndex, uint256 _index, uint256 _price, uint256 _tp, uint256 _sl)

This updates an open limit order.

Inputs

• _pairIndex

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: The index of the trading pair.

• _index

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: The index of the order.

• _price

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: The price level to set (_PRECISION).

• _tp

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: The take-profit price.

• _sl

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: The stop-loss price.

Branches and code coverage

Intended branches

• If the new TP and SL are in the correct range, update the open limit order.

  Test coverage

Negative behavior

• Revert if the time since the order creation is less than the defined timelock period. (Enforces timelock for order updates.)

  Negative test

• Revert if _tp is set and not valid according to order type.

  Negative test

• Revert if _sl is set and not valid according to order type.

Function call analysis

• this.storageT.getOpenLimitOrder(msg.sender, _pairIndex, _index)

  • What is controllable? msg.sender, _pairIndex, and _index.

  • If the return value is controllable, how is it used and how can it go wrong? Returns the open limit order; this limit order is updated and later stored in storage.

  • What happens if it reverts, reenters, or does other unusual control flow? N/A.

• this.storageT.updateOpenLimitOrder(o)

  • What is controllable? o.

  • If the return value is controllable, how is it used and how can it go wrong? Updates the open limit order based on the provided information — no return value.

  • What happens if it reverts, reenters, or does other unusual control flow? If it reverts, the entire call will revert — no reentrancy scenarios.
