Pinescript 在 RSI 低于某个值时发出警报

Question

我是编码新手，我已经找到了如何在 RSI 变为 overbought/oversold 时创建信号。当 RSI 越过该水平时，我想让该警报真正触发。

例如：超买水平设置为 80，蜡烛 1 为 75，蜡烛 2 达到 85，蜡烛 3 然后回落至 75。我希望在蜡烛 3 收盘时生成信号回到下方（希望这是有道理的）。

//@version=4
study(title="RSI cross back", shorttitle="RSI Signal", overlay=true)
// Get user input
rsiSource = input(title="RSI Source", type=input.source, defval=close)
rsiLength = input(title="RSI Length", type=input.integer, defval=10)
rsiOverbought = input(title="RSI Overbought Level", type=input.integer, defval=80)
rsiOversold = input(title="RSI Oversold Level", type=input.integer, defval=20)
// Get RSI value
rsiValue = rsi(rsiSource, rsiLength)
RsiOB = rsiValue >= rsiOverbought
RsiOS = rsiValue <= rsiOversold
// Plot signals to chart
plotshape(RsiOB, title="Overbought", location=location.abovebar, color=color.red, transp=0, style=shape.triangledown)
plotshape(RsiOS, title="Oversold", location=location.belowbar, color=color.green, transp=0, style=shape.triangleup)

Answer 1

您可以使用 barstate.isconfirmed 等待柱线收盘以及 crossover() 和 crossunder() 内置函数

crossunderOB = barstate.isconfirmed and crossunder(rsiValue, rsiOverbought)
crossoverOS = barstate.isconfirmed and crossover(rsiValue, rsiOversold)

Answer 2

“我希望信号在蜡烛 3 的收盘时产生，它向下交叉”

只需使用类似

的东西

cbd=crossunder(rsiValue,75)
cbu=交叉（rsiValue，25）
