在Pine Script策略中跨时间周期调用RSI背离指标的代码请求

代码实现 #

//@version=5
strategy("跨周期RSI背离策略", overlay=true, default_qty_type=strategy.cash, default_qty_value=10000, initial_capital=10000, commission_type=strategy.commission.percent, commission_value=0.1)

// 输入参数
rsiLength = input.int(14, title="RSI周期")
rsiSource = input(close, title="RSI计算源")
higherTF = input.timeframe("D", title="RSI计算的更高时间周期")
overbought = input.int(70, title="超买阈值")
oversold = input.int(30, title="超卖阈值")
stopLossPips = input.int(50, title="止损点数")
takeProfitPips = input.int(100, title="止盈点数")

// 获取跨周期数据
[higherTFClose, higherTFRSI] = request.security(syminfo.tickerid, higherTF, [close, ta.rsi(rsiSource, rsiLength)])

// 检测顶背离：价格创新高，RSI未创新高且处于超买区间
topDivergence = ta.highest(close, 5) == close and ta.highest(higherTFRSI, 5) > higherTFRSI and higherTFRSI > overbought
// 检测底背离：价格创新低，RSI未创新低且处于超卖区间
bottomDivergence = ta.lowest(close, 5) == close and ta.lowest(higherTFRSI, 5) < higherTFRSI and higherTFRSI < oversold

// 绘制背离信号
plotshape(topDivergence, title="顶背离", location=location.belowbar, color=color.red, style=shape.labelup, text="顶背离", textcolor=color.white)
plotshape(bottomDivergence, title="底背离", location=location.abovebar, color=color.green, style=shape.labeldown, text="底背离", textcolor=color.white)

// 策略交易逻辑
if (bottomDivergence)
    strategy.entry("做多", strategy.long)
    strategy.exit("平多", "做多", stop=close - stopLossPips * syminfo.mintick, limit=close + takeProfitPips * syminfo.mintick)

if (topDivergence)
    strategy.entry("做空", strategy.short)
    strategy.exit("平空", "做空", stop=close + stopLossPips * syminfo.mintick, limit=close - takeProfitPips * syminfo.mintick)

关键逻辑说明 #

• 跨周期数据获取：通过request.security()函数拉取指定更高时间周期的收盘价和RSI值，确保背离判断基于大周期的指标趋势
• 背离识别：
  • 顶背离：主图价格创5周期新高，但大周期RSI未同步新高且处于超买区，预示上涨动能衰竭
  • 底背离：主图价格创5周期新低，但大周期RSI未同步新低且处于超卖区，预示下跌动能衰竭
• 风险控制：内置固定点数的止损止盈，可根据品种特性调整参数，也可替换为ATR动态止损
