Up3x1 Krohabor D 策略

概述

该策略使用三条简单移动平均线（快线、中线和慢线）来判断趋势方向。当快线向上穿越中线且快线和中线在当前及上一根K线均位于慢线之上时开多仓。相反条件下开空仓。

仓位在进入时设定止盈、止损以及可选的移动止损，订单按市价执行。

参数

  • Volume – 下单数量。
  • Fast Period – 快速SMA周期。
  • Middle Period – 中速SMA周期。
  • Slow Period – 慢速SMA周期。
  • Take Profit – 止盈距离（价格单位）。
  • Stop Loss – 止损距离（价格单位）。
  • Trailing Stop – 移动止损距离（价格单位）。
  • Candle Type – 使用的K线时间框。

信号

  • 买入 – 快线向上穿越中线且快线和中线均高于慢线。
  • 卖出 – 快线向下穿越中线且快线和中线均低于慢线。

风险控制

  • 入场时设置止盈和止损。
  • 启用后，移动止损会在价格朝有利方向移动时跟随调整。

说明

这是将原始 MQL 策略直接转换为使用 StockSharp 高级 API 和内置指标的版本。
