- conditional execution (valid / invalid)
- arbitrary price discovery (you can use any formula for exchange)
- custom callback during the execution (perform any actions before debiting
funds from your account)

2. Order structure

3. Order execution
order: filled order structure
signature: signedTypedData_v4 signature for makerAddress = wallet (and any data for makerAddress = smart contract)
makingAmount: amount of makerAsset that you want to buy from maker (if > 0 then takingAmount should be 0)
takingAmount: amount of takerAsset that you want to sell to maker (if > 0 then makingAmount should be 0)
thresholdAmount: min return

4. Predicate - condition
nonceEquals and timestampBelow

5. getMakerAmount / getTakerAmount
Default functions:
Execution:

6. Execute predicate / getMakerAmount / getTakerAmount on a separate contract

7. makerAddress == smart contract
In the case of makerAddress = = smart contract address (your strategy), you should implement isValidSignature function
signature can be any data (not necessarily a real signature)
Example:

8. Interaction - any action before transferFrom maker funds
