将显示的指标值增加一个百分比

Question

我正在尝试找到一种方法来制作 RSI 或随机指标，但能够按百分比调整输出。例如，RSI 信号按默认输出的百分比增加。所以它通常显示 70 但增加到 80 例如

有办法做到这一点吗？我已经翻阅手册几个小时了，但找不到它。

//@version=4
study(title="RSI", shorttitle="RSI", format=format.price, precision=2, resolution="")
len = input(14, minval=1, title="Length")
src = input(close, "Source", type = input.source)
rsiValue = rsi(src, len)
i_perc = input(10, title = "Percentage", type = input.float) * 0.01
up = rma(max(change(src), 0), len)
down = rma(-min(change(src), 0), len)
rsi = down == 0 ? 100 : up == 0 ? 0 : 100 - (100 / (1 + up / down))
rsi_increase_conditon = rsiValue >= rsiValue[1] * (1 + i_perc)
rsi_decrease_conditon = rsiValue <= rsiValue[1] * (1 - i_perc)
plot(rsi, "RSI", color=color.white)


hline(70, "OBBand", color=color.red, linestyle=hline.style_solid)
hline(20, "XOSBand", color=color.blue, linestyle=hline.style_solid)
hline(50, "Mid", color=color.gray, linestyle=hline.style_solid)
hline(80, "XOBBand", color=color.blue, linestyle=hline.style_solid)
hline(30, "OSBand", color=color.red, linestyle=hline.style_solid)

Answer 1

i_perc = input(10, title = "Percentage", type = input.float) * 0.01
...
rsi_increase_conditon = rsiValue >= rsiValue[1] * (1 + i_perc)
rsi_decrease_conditon = rsiValue <= rsiValue[1] * (1 - i_perc)

plotshape(rsi_increase_conditon and not rsi_increase_conditon[1], title = "RSI Increase %", style = shape.triangleup, location = location.belowbar, size = size.normal)

plotshape(rsi_decrease_conditon and not rsi_decrease_conditon[1], title = "RSI Decrease %", style = shape.triangledown, location = location.abovebar, size = size.normal)
