如何在TradingView的Pine Script策略中设置回测起止日期

一、设置回测起止日期的两种方法 #

方法1：界面直接设置（无需改代码） #

• 打开策略回测界面，点击右上角齿轮形状的「设置」图标
• 切换到「输入」标签页，拉到最底部找到「回测日期范围」选项
• 勾选「使用自定义日期范围」，选择你需要的起止日期后确认即可

方法2：修改代码固定日期范围（适合需要锁定回测区间的场景） #

你当前的代码是指标脚本（使用study()函数），本身不带回测配置。改成策略脚本并添加日期过滤的步骤如下：

1. 把开头的study()替换为strategy()，启用策略回测功能
2. 加入日期过滤逻辑，只在指定区间内触发交易信号

下面是修改后的完整代码，你可以自行调整startDate和endDate的数值：

// This is combo strategies for get a cumulative signal. 
//
// First strategy
// This System was created from the Book "How I Tripled My Money In The 
// Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
// The strategy buys at market, if close price is higher than the previous close 
// during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50. 
// The strategy sells at market, if close price is lower than the previous close price 
// during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
//
// Second strategy
//    This indicator plots the oscillator as a histogram where blue denotes 
//    periods suited for buying and red . for selling. If the current value 
//    of AO (Awesome Oscillator) is above previous, the period is considered 
//    suited for buying and the period is marked blue. If the AO value is not 
//    above previous, the period is considered suited for selling and the 
//    indicator marks it as red.
//  You can make changes in the property for set calculating strategy MA, EMA, WMA

// 自定义回测日期范围：格式为timestamp(年, 月, 日, 时, 分)
startDate = timestamp(2020, 1, 1, 0, 0) // 起始日期
endDate = timestamp(2024, 12, 31, 23, 59) // 结束日期
inDateRange = time >= startDate and time <= endDate
