Exp Cronex MFI 策略
概述
本策略复刻了 Exp_CronexMFI 智能交易系统。它对资金流量指标(MFI)进行两次平滑处理,并在两条线发生交叉时采取逆势交易。移植版本保持了原始的反转思想,并将所有参数暴露为 StockSharp 策略参数。
工作流程
- 订阅所选蜡烛序列(默认使用 4 小时周期)。
- 按照设定周期计算 Money Flow Index。
- 使用指定的平滑方法进行两级处理:第一次得到快速 Cronex 线,第二次对快速线再次平滑生成慢速线。
- 根据
SignalShift保存历史快/慢线组合,模仿 MQL 中的SignalBar延迟。 - 当快速线从上向下穿越慢速线时,关闭空头(若允许)并开立/加仓多头;当快速线从下向上穿越慢速线时,关闭多头并开立/加仓空头。
- 所有订单均以策略
Volume的数量按市价发送,并可分别禁用多头或空头方向。
策略仅在蜡烛收盘后评估信号,以与 MetaTrader 版本保持一致。
参数
| 名称 | 类型 | 默认值 | 说明 |
|---|---|---|---|
MfiPeriod |
int |
25 |
Money Flow Index 的周期长度。 |
FastPeriod |
int |
14 |
第一次平滑(快速线)的周期。 |
SlowPeriod |
int |
25 |
第二次平滑(慢速线)的周期。 |
SignalShift |
int |
1 |
等待的已完成蜡烛数量,用于延迟信号。 |
Smoothing |
SmoothingMethod |
Simple |
两个平滑阶段使用的移动平均算法。 |
EnableLongEntries |
bool |
true |
允许开立或加仓多头头寸。 |
EnableShortEntries |
bool |
true |
允许开立或加仓空头头寸。 |
EnableLongExits |
bool |
true |
允许信号平掉已有多头。 |
EnableShortExits |
bool |
true |
允许信号平掉已有空头。 |
CandleType |
DataType |
TimeFrame(4h) |
用于计算的蜡烛类型。 |
Volume |
decimal |
1 |
开仓时使用的下单数量。 |
平滑方式
原指标包含多个自定义模式,移植版本将其映射到内置移动平均:
| MQL 模式 | SmoothingMethod 取值 |
说明 |
|---|---|---|
| SMA | Simple |
简单移动平均。 |
| EMA | Exponential |
指数移动平均。 |
| SMMA | Smoothed |
平滑移动平均(Wilder)。 |
| LWMA | Weighted |
线性加权平均。 |
| JJMA / JurX / ParMA / T3 / VIDYA / AMA | DoubleExponential, TripleExponential, Hull, ZeroLagExponential, ArnaudLegoux, KaufmanAdaptive |
选择最接近的自适应平滑方式。 |
与 MQL 版本的差异
- 无法在蜡烛层面区分真实与勾选成交量,使用的是 StockSharp 蜡烛提供的总量数据。
- 仅使用市价单进行仓位管理;原策略的延迟通过
SignalShift参数模拟。 - 止损和止盈需要通过额外的风险控制或保护模块来设置。
使用建议
- 根据标的的流动性选择适当的蜡烛周期;默认的 4 小时与源策略一致。
- 当需要额外确认时,可提高
SignalShift的取值。 - 建议结合
StartProtection或其他风控机制限制潜在亏损。
