RSI跟踪pinescript

Question

我需要帮助在RSI pinescript=假设'X‘的价格是6,000美元，它上升到7,000美元，RSI也高于band70。现在我希望警报在它跌到6980美元时被激活(即回落20美元)。如何在RSI pinescript中编写此跟踪脚本。

 //@version=4
study("rsi overbought", overlay=true)

rsiSource = input(title="RSI Source", type=input.source, defval=close)
rsiLength = input(title="RSI Length", type=input.integer, defval=14)
rsiOverbought = input(title="RSI Overbought Level", type=input.integer, defval=70)


rsiValue = rsi(rsiSource, rsiLength)
isRsiOB = rsiValue >= rsiOverbought


plotshape(isRsiOB, title="Overbought", location=location.abovebar, color=color.red, transp=0, style=shape.triangledown, text="Sell")

alertcondition(isRsiOB , title="RSI Signal!", message="RSI Signal Detected for {{ticker}}")  

Answer 1

试试像这样的东西

trail_high = highest(high,20) //highest high of 20 bars

down_num = 20 //the trailing 20$

if( low < trail_high - down_num)
    alert_code
