DVD 100-50 Cent 策略

概述

DVD 100-50 cent 是一个从 MT4 专家顾问移植而来的逆势限价策略。算法同时观察 M1、M30、H1、D1 四个周期，对潜在交易机会打分，然后在最近的“100 价位”附近挂出买入或卖出限价单。当挂单成交后，策略会按照预先计算好的止损与止盈水平管理仓位。

指标与数据

  • RAVI（Range Action Verification Index）：在 H1 和 D1 周期使用 SMA(2) 与 SMA(24) 对开盘价计算得到。
  • 原始 K 线数据：在 M1、M30、H1 周期用于检测瞬时尖峰、盘整区间以及短期动量特征。
  • 价格栅格：将最新价格四舍五入到两个小数位，并用 PointFromLevelGoPips（0.1 点单位）偏移以构建“100 价位”网格。

入场逻辑

  1. 根据最新的 M1 收盘价，取两位小数并加上 PointFromLevelGoPips（默认 50 ⇒ 5 点）得到目标 100 价位。
  2. 初始化内部评分 BAL=0，然后根据下列条件累加或扣减分数：
    • 趋势过滤：当 H1 RAVI 小于 0（做多）或大于 0（做空）时加 10 分。
    • 小时级尖峰确认：若前两根 H1 K 线高点/低点突破网格 RiseFilterPips，加 7 分。
    • 结构确认：若当前 M1 收盘重新站回目标价位，且最近三根 H1 的低点/高点一直位于安全缓冲区（PointFromLevelGoPips ± 30 * 0.1 点）之外，加 45 分。
    • 波动性保护：若近期 M1 的高点/低点超过 HighLevelPips（默认 600 ⇒ 60 点），或在 D1 RAVI 强趋势背景下出现快速动量爆发，则减 50 分。
    • 突破过滤：若过去 15 根 H1 K 线都未触及 LowLevel2Pips，减 50 分。
    • 盘整过滤：若最近 8 根 M30 K 线全部位于 LowLevelPips 区间内，减 50 分。
  3. 仅当最终得分 ≥ 50 且当前没有持仓或挂单时才会提交新的限价单。

挂单规则

  • 买入限价单：在最新 M1 收盘价下方 10 点处挂单。止损位于限价价位下 StopLossPips 点，止盈位于其上 TakeProfitPips 点。如果 D1 RAVI 在过去四天内呈现 -1 到 +5 区间的阶梯式上涨，则额外延长止盈 25 点。
  • 卖出限价单：在最新 M1 收盘价上方 7 点处挂单，止损与止盈规则完全对称。当 D1 RAVI 在 -5 到 -1 区间持续下降时，同样延长止盈 25 点。
  • 挂单的有效期为 OrderExpiryMinutes 分钟（默认 20 分钟），超时未成交会自动撤单并清空对应的保护水平。

仓位管理

  • 挂单成交后，策略会保存对应的止损/止盈价格，并在价格触及时发送市价单平仓。
  • 本移植版本不启用追踪止损——原始 EA 默认关闭该功能。
  • 只要存在持仓或挂单，就不会生成新的交易信号。

资金管理

  • 当 UseMoneyManagement 为真时，仓位规模按照 MT4 原始公式计算：以 TradeSizePercent 为基础，结合账户类型（迷你或标准）并限制在 [0.1, MaxVolume]（迷你）或 [1, MaxVolume]（标准）范围内。
  • 关闭资金管理时，使用参数 FixedVolume 指定的固定手数。
  • 当账户权益低于 MarginCutoff 时暂停开仓。

参数

参数 说明 默认值
AccountIsMini 是否按迷你账户规则四舍五入仓位 true
UseMoneyManagement 启用资金管理 true
TradeSizePercent 每笔交易使用的权益百分比 10
FixedVolume 关闭资金管理时的固定手数 0.01
MaxVolume 最大可下单手数 4
StopLossPips 止损距离（点） 210
TakeProfitPips 止盈距离（点） 18
PointFromLevelGoPips 100 价位基准偏移（0.1 点单位） 50
RiseFilterPips H1 尖峰过滤阈值（0.1 点单位） 700
HighLevelPips M1 尖峰过滤阈值（0.1 点单位） 600
LowLevelPips M30 盘整区间阈值（0.1 点单位） 250
LowLevel2Pips H1 突破确认阈值（0.1 点单位） 450
MarginCutoff 停止开仓的最低权益 300
OrderExpiryMinutes 挂单有效期（分钟） 20

使用提示

  • 策略依赖四个周期的完结 K 线，请确保数据源同时提供 M1、M30、H1、D1 的同步历史数据。
  • 止损和止盈通过市价单执行，以模拟 MT4 中挂单附带 SL/TP 的行为。
  • 算法对点值设置较为敏感，请确认交易品种的 PriceStep 与 Decimals 属性配置正确。
