Bruno 策略
Bruno 策略来源于 MetaTrader 5 平台,是一个典型的趋势追踪系统。本移植版本沿用了全部过滤条件:带有方向性指标线的 ADX、两条指数移动平均线(EMA 8 与 EMA 21)、MACD(13、34、8)、随机指标(21、3、3)以及参数为 0.055/0.21 的抛物线 SAR 斜率。每当某个过滤器支持当前方向时,就会把基础手数乘以预设倍数。如果同一根 K 线上多空信号同时被放大,则放弃交易以避免冲突。
交易逻辑
- 趋势方向
- 当
+DI > -DI且+DI > 20时加强做多信号。 - 当
+DI < -DI且+DI < 40时加强做空信号。
- 当
- 动量确认
- 做多需要 EMA(8) 高于 EMA(21),随机指标 %K 高于 %D 且 %K 低于超买线(默认 80)。
- 做空需要 EMA(8) 低于 EMA(21),随机指标 %K 低于 %D 且 %K 高于超卖线(默认 20)。
- MACD 滤波
- 多头:MACD 主线在 0 轴之上并且高于信号线。
- 空头:MACD 主线在 0 轴之下并且低于信号线。
- Parabolic SAR 斜率
- 当前两个 SAR 值上升且 EMA(8) > EMA(21) 时进一步确认多头。
- 当前两个 SAR 值下降且 EMA(8) < EMA(21) 时进一步确认空头。
每满足一个条件,BaseVolume 会乘以 SignalMultiplier(默认 1.6)。任意时刻只允许一个方向成立;最终信号出现后,策略会先平掉反向仓位,再按新的手数开仓,并把当前收盘价记录为入场价。
仓位管理
- 止损/止盈:以“调整后的点值”表示的固定距离,与原始 EA 保持一致。当价格在 K 线内触及任一水平时立即平仓。
- 移动止损:当浮动盈利超过
TrailingStop + TrailingStep点后启用,把止损线拉到距离价格TrailingStop点的位置,只有在盈利继续增加至少TrailingStep点时才会再次上移。 - 信号冲突:若多空过滤条件同时满足,则本根 K 线不入场。
参数说明
| 分类 | 参数 | 说明 |
|---|---|---|
| 交易 | BaseVolume |
乘法前的基础手数。 |
| 交易 | SignalMultiplier |
每个确认过滤器对手数的乘数。 |
| 风险控制 | StopLossPips / TakeProfitPips |
止损与止盈距离(调整点)。设为 0 代表禁用。 |
| 风险控制 | TrailingStopPips / TrailingStepPips |
移动止损的距离与最小步长。 |
| 指标 | AdxPeriod, AdxPositiveThreshold, AdxNegativeThreshold |
ADX 周期与方向性阈值。 |
| 指标 | FastEmaPeriod, SlowEmaPeriod |
趋势确认所用 EMA 的周期。 |
| 指标 | MacdFastPeriod, MacdSlowPeriod, MacdSignalPeriod |
MACD 参数。 |
| 指标 | StochasticPeriod, StochasticKsmoothing, StochasticDsmoothing, StochasticOverbought, StochasticOversold |
随机指标设置。 |
| 通用 | CandleType |
全部计算使用的时间框架(默认 1 小时)。 |
其他说明
- 点值换算遵循 MetaTrader 规则:报价保留 3 或 5 位小数的品种将点值乘以 10。
- 抛物线 SAR 的加速步长为
0.055,最大加速为0.21,与原始 EA 一致。 - 手数放大逻辑被保留,但在 StockSharp 中以单一净头寸的方式进行管理。
