量化合约系统开发是指开发一种能够自动化执行交易策略的软件系统,该系统能够根据预设的规则和条件自动执行交易,从而实现量化交易。
量化合约系统开发部署需要具备以下技能: 1. 编程语言:需要熟练掌握至少一种编程语言,如Python、C++等。 2. 数据分析:需要具备数据分析的能力,能够对市场数据进行分析和处理,从而制定交易策略。 3. 金融知识:需要了解金融市场的基本知识,如股票、期货、期权等。 4. 交易系统设计:需要设计和开发交易系统,包括交易策略、交易规则、交易接口等。 5. 风险控制:需要具备风险控制的能力,能够对交易风险进行评估和控制。 6. 系统优化:需要对系统进行优化,提高交易效率和稳定性。 总之,量化合约系统开发需要综合运用编程、数据分析、金融知识和风险控制等多方面的技能,才能够开发出高效、稳定的量化交易系统。
Deployer API deployer对象提供了方法用于简化智能合约的部署。deployer.deploy(contract, args…, options)参数contract为使用artifacts.require引用的智能合约对象。参数args...为智能合约的构造函数的参数,用于初始化智能合约。参数options用于指定from,gas及overwrite等信息,overwrite用于重新部署某个已经完成部署的智能合约,默认的options参数在bottle.js文件中配置
例子:
// Deploy a single contract without constructor arguments
deployer.deploy(A);
// Deploy a single contract with constructor arguments
deployer.deploy(A, arg1, arg2, ...);
// Don't deploy this contract if it has already been deployed
deployer.deploy(A, {overwrite: false});
// Set a maximum amount of gas and from
address for the deployment
deployer.deploy(A, {gas: 4612388, from: "0x...."});
// External dependency example:
//
// For this example, our dependency provides an address when we're deploying to the
// live network, but not for any other networks like testing and development.
// When we're deploying to the live network we want it to use that address, but in
// testing and development we need to deploy a version of our own. Instead of writing
// a bunch of conditionals, we can simply use the overwrite
key.
deployer.deploy(SomeDependency, {overwrite: false});
通过promise对象可以运行任意的部署步骤并调用指定的智能合约内部方法来进行交互
例子:
var ERC20 = artifacts.require("../contracts/Erc20.c")
module.exports = function (deployer, a) {
deployer.deploy(ERC20, "1000000", "bitcoin", "BTC").then(function (instance) {
deploy = instance;
return deploy.GetTotalSupply()
}).then(function (totalSupply) {
console.log("totalSupply", totalSupply.toString());
return deploy.GetDecimals();
}).then(function (decimals) {
console.log("decimals", decimals.toString());
return deploy.GetTokenName();
}).then(function (tokenName) {
console.log("tokenName", tokenName);
return deploy.GetAmount("0x122369f04f32269598789998de33e3d56e2c507a")
}).then(function (balance) {
console.log("balance", balance.toString());
})
};
