Question

我想在一个内置指示器上绘制两条水平线我试图创建一个自定义脚本：

study("Lines")
p1 = plot(0.1)
p2 = plot(0.25)
fill(p1, p2, color=green)

所以，我可以在一个单独的小部件中绘制这些行，但是如何在另一个指示符（CMF）上绘制它们呢？

Answer 1

这是你想要实现的目标吗？

//@version=1
study(title="Relative Strength Index", shorttitle="My StockRSI with RSI")
src = close, len = input(8, minval=1, title="Length")
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))

plot(rsi, title='RSI',color=#0000ff, transp=0, linewidth=1)
band2 = hline(70, title="Upper band", color=red, linestyle=solid, linewidth=1)
band1 = hline(50, title="Middle band", color=olive, linestyle=solid, linewidth=1)
band0 = hline(30, title="Lower band", color=teal, linestyle=solid, linewidth=1)


//Stochastic RSI//
smoothK = input(3, minval=1)
smoothD = input(3, minval=1)
lengthRSI = input(14, minval=1)
lengthStoch = input(14, minval=1)

rsi1 = rsi(src, lengthRSI)
k = sma(stoch(rsi1, rsi1, rsi1, lengthStoch), smoothK)
d = sma(k, smoothD)

plot(k, title='Smooth K',color=teal, transp=10)
plot(d, title='Smooth D',color=#ff7f00, transp=10)

h0 = hline(100, title="Upper band", linestyle=solid, linewidth=1, color=olive)
h1 = hline(0, title="Lower band", linestyle=solid, linewidth=1, color=olive)
