量化Python交易系统开发技术,合约量化系统开发源码部署方案

  智能合约不一定构成合法的有效约束协议。(刘森-180-2857-8624)一些法律学者声称,智能合约不是法律协议,而是履行源自其他协议的义务的手段,例如用于支付义务自动化的技术手段或代币或加密货币转让中的义务。

 量化交易的特点:

 1:纪律性

 Quantitative trading is based on automatic order placement,which ensures the objectivity and discipline of decision-making.

 2:大数据

 In the process of decision-making and research,quantitative trading will introduce a large amount of historical data for rapid calculation and analysis,and find out a set of replicable rules,which will be executed by machines.

 3:响应速度快

 This is the most obvious advantage of quantitative trading.Generally,the response speed of analysis and operation can reach the second level.High-frequency trading is even subtly calculated.When arbitrage opportunities appear in the market,only the fastest algorithm and network can seize them

 得分角度(因素)通常有以下几点:

 1)Value factor:see the absolute valuation and relative valuation of the stock(valuation percentage points).Generally,stocks with low valuations score high.

 2)Growth factors:see revenue,net profit,cash flow growth rate and other indicators.The higher the growth rate,the higher the score.

 3)Profit factor:see gross profit rate,net profit rate,ROE and other indicators.The stronger the profitability,the higher the score.

 4)Scale factor:stock market value and circulating market value.Who gets the highest score depends on whether the fund manager prefers large-cap stocks or small-cap stocks.

 5)Momentum factor:It is generally understood that momentum factor analysis is technical analysis.

 智能合约,是一种计算机程序或事务协议,其目的是自动执行,控制或文档根据的条款在法律上相关的事件和行为的合同或协议。智能合约的目标是减少可信赖中介人的需求、仲裁和执行成本,欺诈损失以及减少恶意和意外例外。

 pragma solidity>=0.7.0;

 contract Coin{

 //The keyword"public"makes variables

 //accessible from other contracts

 address public minter;

 mapping(address=>uint)public balances;

 //Events allow clients to react to specific

 //contract changes you declare

 event Sent(address from,address to,uint amount);

 //Constructor code is only run when the contract

 //is created

 constructor(){

 minter=msg.sender;

 }

 //Sends an amount of newly created coins to an address

 //Can only be called by the contract creator

 function mint(address receiver,uint amount)public{

 require(msg.sender==minter);

 require(amount<1e60);

 balances[receiver]+=amount;

 }

 //Sends an amount of existing coins

 //from any caller to an address

 function send(address receiver,uint amount)public{

 require(amount<=balances[msg.sender],"Insufficient balance.");

 balances[msg.sender]-=amount;

 balances[receiver]+=amount;

 emit Sent(msg.sender,receiver,amount);

 }

 }
