Surefirething 策略
概述
Surefirething 策略复刻了 MetaTrader 5 上的经典智能交易系统,它会在最新完成的K线收盘价附近同时挂出对称的买入和卖出限价单。每根K线结束后都会重建网格,所有止损与止盈都以点(pip)为单位管理,并且会在服务器时间23:50强制平掉全部仓位。
K线处理
- 支持可配置的K线类型(默认:1小时周期)。
- 当一根K线收盘后,计算放大的区间:
range = (high - low) * 1.1。
- 根据该区间得到两个突破价位:
L4 = close - range / 2:买入限价单。
H4 = close + range / 2:卖出限价单。
- 在发布新网格之前会取消已有的挂单,保证始终只有一张买入限价单和一张卖出限价单。
挂单管理
- 在
L4 和 H4 位置以设定的下单量挂出限价单。
- 只要有一笔交易成交,就会立刻取消另一侧的挂单。
- 每天 23:50(服务器时间)执行收盘流程:
- 取消所有剩余挂单。
- 如有持仓则以市价全部平仓。
- 重置止损与止盈跟踪,为下一交易日做准备。
风险控制
- 止损与止盈距离以点数表示,并通过合约的最小报价步长转换为具体价格(对 5 位和 3 位小数的品种自动换算成传统的 1 个 pip)。
- 可以启用点数单位的移动止损。当价格向有利方向移动超过
TrailingStopPips + TrailingStepPips 时,止损会被推进到:多单为 当前价 - TrailingStopPips,空单为 当前价 + TrailingStopPips。
- 每根K线都会检查是否触发止损或止盈。一旦价格穿越相应价位,立即用市价单离场。
参数
OrderVolume – 两侧限价单的基础下单量(默认值 0.1)。
StopLossPips – 止损距离(点)(默认值 50)。
TakeProfitPips – 止盈距离(点)(默认值 50)。
TrailingStopPips – 移动止损距离(点)(默认值 25)。
TrailingStepPips – 触发移动止损所需的额外点数(默认值 1)。启用移动止损时必须大于0。
CandleType – 用于计算的K线类型(默认:1小时)。
说明
- 实现遵循原始 MQL 版本的约束:启用移动止损时不允许将移动步长设为0。
- 本策略暂不提供 Python 版本。
