Hulk Grid Algorithm V2 策略

该网格策略在用户设定的中间价附近放置十个分层买入限价单，越靠近中间价数量越大。当价格跌破最低网格的止损或升破最高网格的止盈时，策略平掉所有仓位并取消剩余订单。

详情

  • 入场条件：从最低到最高的十个买入限价单网格。
  • 多空方向：仅做多。
  • 出场条件：价格触发最低网格下方的止损或最高网格上方的止盈。
  • 止损：基于百分比的止损和止盈。
  • 默认参数：
    • MidPrice = 0
    • StopLossPercent = 2.0
    • TakeProfitPercent = 2.0
    • GridStep = 200
    • Lot = 50
    • CandleType = TimeSpan.FromMinutes(1)
  • 过滤器：
    • 类别：Grid
    • 方向：多头
    • 指标：无
    • 止损：是
    • 复杂度：基础
    • 周期：任意
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
