请求修改带布林带的RSI指标代码：实现RSI线分色显示

直接替换原代码中RSI的绘图语句，通过条件判断即可实现RSI线按区间变色的需求。以下是修改后的完整代码：

//@version=5
indicator ("Bollinger bands on RSI", overlay = false)

// INPUT CONTROLS

LENGTHSMA = input.int(title = "SMA", defval = 20, minval = 1, maxval = 30, step= 1)
MULTI = input.int(title = "MULTI", defval = 2, minval = 1, maxval = 3, step = 1)
LENGTHRSI =  input.int(title= "LRSI", defval = 14, minval = 1, maxval = 30, step = 1) 


// TRADING INDICATORS

// Bollinger band on RSI indicator
RSI = ta.rsi(close, LENGTHRSI)
STD = ta.stdev(RSI, LENGTHSMA)
SMA= ta.sma (RSI, LENGTHSMA)

upperband = SMA + (STD * MULTI) 
lowerband = SMA - (STD * MULTI)

plot (upperband)
plot (lowerband)
plot (SMA)

// 修改后的RSI绘图逻辑，实现区间变色
plot(RSI, color = RSI > 60 ? color.new(color.green, 0) : RSI < 40 ? color.new(color.red, 0) : color.new(color.yellow, 0), linewidth = 1)

hline (80)
hline (60)
hline (40)
hline (20)

关键修改说明 #

• 利用Pine Script的三元运算符（? :）实现多条件判断：
  • 当RSI > 60时，线条显示绿色
  • 当RSI < 40时，线条显示红色
  • 处于40-60区间时，线条显示黄色
• 原代码的布林带、RSI计算等功能完全保留，仅调整了RSI线的颜色规则
