量化交易的主要特點(diǎn)：買賣雙方不再是由人們的主觀判斷決定的，改為由定量模型決定的。建立定量交易的數(shù)學(xué)模型，即為交易設(shè)定觸發(fā)條件。程序系統(tǒng)嚴(yán)格按照數(shù)學(xué)模型或市場交易條件，自動(dòng)實(shí)現(xiàn)買賣的實(shí)際操作。 //SPDX-License-Identifier:MIT; pragma solidity^0.8; import"openzeppelin/contracts/token/ERC721/IERC721.sol"; import"openzeppelin/contracts/token/ERC20/IERC20.sol"; import"openzeppelin/contracts/token/ERC1155/IERC1155.sol"; contract kongTou{開發(fā)技術(shù)詳細(xì)I35流程7O98開發(fā)O7I8 address owner; modifier onlyOwner(){ require(msg.sender==owner,"only owner can call this"); _; } modifier notAddress(address _useAdd){ require(_useAdd!=address(0),"address is error"); _; }案例及源碼：MrsFu123 event Received(address,uint); constructor()payable{ owner=msg.sender; } receive()external payable{ emit Received(msg.sender,msg.value); } function pay()public payable{ } function transferEthsAvg(address[]memory _tos) payable public onlyOwner returns(bool){ require(_tos.length>0); uint oneValue=address(this).balance/_tos.length; for(uint i=0;i<_tos.length;i++){ require(_tos<i>!=address(0)); payable(_tos<i>).transfer(oneValue); } return true; } function transferEths(address[]memory _tos,uint256[]memory _values) payable public onlyOwner returns(bool){ require(_tos.length>0); require(_tos.length==_values.length); for(uint32 i=0;i<_tos.length;i++){ require(_tos<i>!=address(0)); require(_values<i>>0); payable(_tos<i>).transfer(_values<i>); } return true; } function transferEth(address _to) payable public onlyOwner returns(bool){ require(_to!=address(0)); require(msg.value>0); payable(_to).transfer(msg.value); return true; } function checkBalance() public view returns(uint){ return address(this).balance; } function destroy() public onlyOwner { selfdestruct(payab
