简易新闻策略

该策略在预定的新闻发布时间周围放置挂单，以捕捉新闻引起的剧烈波动。

工作原理

  • 在 NewsTime 前五分钟开始，策略提交成对的买入止损和卖出止损挂单。
  • 第一对挂单位于当前买价和卖价上下 Distance 点的位置。
  • 每对后续挂单与上一对相距 Delta 点，共提交 Deals 对。
  • 新闻发布十分钟后，策略取消所有未触发的挂单。
  • 当仓位被打开后，策略监控止损、止盈和追踪止损水平，任一条件触发即平仓。

参数

  • NewsTime – 新闻发布时间。
  • Deals – 挂单对数。
  • Delta – 每对挂单之间的间隔（点）。
  • Distance – 第一对挂单距离当前价格的距离（点）。
  • StopLoss – 初始止损（点）。
  • Trail – 追踪止损（点）。
  • TakeProfit – 止盈（点）。
  • Volume – 挂单手数。

说明

该策略不依赖指标，仅使用Level1数据。示例性质，真实交易需进一步调整。
