Get Rsi strength indicator Code That Actually Works

//@version=5
indicator("HorizonAI - RSI Trend Strength", overlay=false, precision=2)

// Input Parameters
rsiLength = input.int(14, "RSI Length", minval=1)
rsiSource = input.source(close, "Source")
overbought = input.int(70, "Overbought Level")
oversold = input.int(30, "Oversold Level")
signalSmooth = input.int(7, "Signal Smoothing")

// RSI Calculation
rsiValue = ta.rsi(rsiSource, rsiLength)
signalLine = ta.ema(rsiValue, signalSmooth)

// Strength Logic: Identifying Momentum Clusters

               rsiValue < oversold ? color.new(color.green, 0) : 
               color.new(color.gray, 50)

// Visual Plots
h1 = hline(overbought, "Overbought", color=color.new(color.red, 50), linestyle=hline.style_dashed)
h2 = hline(oversold, "Oversold", color=color.new(color.green, 50), linestyle=hline.style_dashed)
hline(50, "Median", color=color.new(color.gray, 70))

fill(h1, h2, color=color.new(color.blue, 95), title="Neutral Zone")

plot(rsiValue, "RSI Value", color=strengthColor, linewidth=2)
plot(signalLine, "Signal Line", color=color.new(color.yellow, 0), linewidth=1)

// Background Highlighting for Extreme Strength
bgColor = (rsiValue >= 80) ? color.new(color.red, 85) : (rsiValue <= 20) ? color.new(color.green, 85) : na
bgcolor(bgColor)

// Alert Conditions
