EMA WMA RSI
概述
EMA WMA RSI 是 MetaTrader 4 专家顾问“EMA WMA RSI”(作者 cmillion)的 StockSharp 版本。原始 EA 在每根 K 线的开盘价上计算指数移动平均线(EMA)与线性加权移动平均线(WMA),并使用相同价格源计算的相对强弱指标(RSI)作为方向过滤器。移植后的策略保留了原有指标逻辑,只在已完成的蜡烛上运作,同时复刻了资金管理选项:可选的反向仓位平仓、以点为单位的止损/止盈,以及三种拖尾止损方式(固定距离、最近分形或近期蜡烛极值)。
策略针对单一品种运行,时间框架由 Candle Type 参数决定。所有点值均按 MetaTrader 中的“Point”(最小跳动)换算,因此请在证券信息里填充 Security.Step、Security.PriceStep 与 Security.StepPrice 等元数据,以便正确转换价格距离。
交易逻辑
指标
- EMA – 由
EMA Period 控制周期,输入为蜡烛开盘价。
- WMA – 周期由
WMA Period 决定,同样使用开盘价序列。
- RSI –
RSI Period 控制周期,同样基于开盘价。
指标准备只在蜡烛收盘时更新;为了复现原始 EA 的“新柱执行”行为,策略会保存上一根柱的 EMA/WMA 数值,与当前柱的数值比较。
入场条件
- 多头条件
- 当前 EMA 低于 WMA,而上一根柱的 EMA 高于 WMA(向下交叉)。
- RSI 大于 50。
- 如当前持有空头仓位,在
Close Counter Trades 为真时先平掉空头;若关闭此选项则忽略信号直到仓位扁平。
- 条件满足后按固定手数或风险百分比下市场买单。
- 空头条件 – 逻辑完全对称:EMA 向上穿越 WMA、上一根柱 EMA 低于 WMA、RSI 小于 50,并根据设置处理已有多头。
离场机制
- 初始保护 –
Stop Loss (points) 与 Take Profit (points) 会通过最小跳动转换成绝对价差,设置为 0 表示关闭对应保护。
- 拖尾止损
Trailing Stop (points) 大于 0 时采用固定距离拖尾,依据最新收盘价向有利方向收紧。
- 拖尾距离为 0 时启用自适应模式:
Trailing Source = CandleExtremes:从最近的已完成蜡烛中寻找满足至少 5 点缓冲的最低价/最高价。
Trailing Source = Fractals:回溯已确认的比尔·威廉姆斯分形(前后各两根蜡烛),同样要求至少 5 点缓冲。
- 只有当价格越过开仓价后,拖尾才会启动,贴合原函数
SlLastBar 的行为。
- 平仓执行 – 若当根蜡烛的极值触碰拖尾价或止盈价,即以市价平仓并重置内部状态。
仓位管理
Fixed Volume 指定固定下单手数(与原 EA 的 Lot 参数对应)。
- 将
Fixed Volume 设为 0 时启用风险百分比头寸控制。策略会利用有效的止损距离(止损或拖尾)及 Security.StepPrice 估算每单位仓位的货币风险,再根据 Risk % 分配权益。如果固定手数与风险百分比同时为 0,信号将被忽略。

实现细节
- 点值换算依赖
Security.Step/Security.PriceStep 与 Security.StepPrice,请确保品种信息完整。
- 策略仅处理收盘蜡烛,并以开盘价更新指标,符合原始 MQL4 代码的逻辑。
- 拖尾逻辑保留至少 5 点缓冲,避免止损过于靠近当前价格。
- 当关闭反向平仓时,策略始终保持单向净仓,不会同时持有多空。
- 本目录仅包含 C# 版本,暂无 Python 实现。
