The Problem

You've scoured YouTube and forums for a solid buy and sell indicator like SuperTrend or divergence signals, but free Pine Scripts repaint or throw endless errors when you tweak them.

Our built-in compiler auto-checks and fixes every error, so you always receive flawless code. One-click copy-paste into TradingView, and your signals are live—no debugging hell.

Buy and sell indicator — Pine Script

This SuperTrend indicator dynamically plots trailing buy/sell lines based on ATR, generating clear BUY/SELL labels and phone alerts on trend flips for precise entries and exits.

Pine Script
//@version=5
indicator("SuperTrend Buy Sell Indicator", shorttitle="ST Buy/Sell", overlay=true)

// Input parameters for customization
atrPeriod = input.int(10, title="ATR Length", minval=1, maxval=50)
factor = input.float(3.0, title="Factor", minval=0.01, step=0.01)
showSignals = input.bool(true, title="Show Buy/Sell Shapes")
showAlerts = input.bool(true, title="Enable Alerts")
upColor = input.color(color.green, title="Up Trend Color")
downColor = input.color(color.red, title="Down Trend Color")

// Calculate ATR
atrValue = ta.atr(atrPeriod)

// SuperTrend calculation
upperBand = hl2 + (factor * atrValue)
lowerBand = hl2 - (factor * atrValue)

prevUpperBand = nz(upperBand[1])
prevLowerBand = nz(lowerBand[1])
prevSuperTrend = nz(supertrend[1])

supertrend = 0.0
supertrend := close[1] > prevSuperTrend ? math.max(lowerBand, supertrend[1]) : math.min(upperBand, supertrend[1])

// Direction: -1 for uptrend (buy), 1 for downtrend (sell)
direction = 1
 direction := close > supertrend[1] ? -1 : 1

// Plot SuperTrend line
superTrendPlot = plot(supertrend, title="SuperTrend", color=direction == -1 ? upColor : downColor, linewidth=2)

// Buy and Sell conditions
buySignal = ta.change(direction) == -2  // Switch to uptrend
sellSignal = ta.change(direction) == 2 // Switch to downtrend

// Visual shapes for signals
plotshape(showSignals and buySignal, title="Buy Signal", location=location.belowbar, style=shape.labelup, size=size.normal, color=upColor, textcolor=color.white, text="BUY")
plotshape(showSignals and sellSignal, title="Sell Signal", location=location.abovebar, style=shape.labeldown, size=size.normal, color=downColor, textcolor=color.white, text="SELL")

// Background color for trend
bgcolor(direction == -1 ? color.new(upColor, 95) : color.new(downColor, 95), title="Trend Background")

// Alerts
if showAlerts
    alertcondition(buySignal, title="Buy Alert", message="SuperTrend Buy Signal: Price flipped to uptrend. Enter long.")
    alertcondition(sellSignal, title="Sell Alert", message="SuperTrend Sell Signal: Price flipped to downtrend. Enter short or exit.")

// Table for info (optional display)
var table infoTable = table.new(position.top_right, 2, 2, bgcolor=color.white, border_width=1)
if barstate.islast
    table.cell(infoTable, 0, 0, "Trend", text_color=color.black)
    table.cell(infoTable, 1, 0, direction == -1 ? "UP" : "DOWN", text_color=direction == -1 ? upColor : downColor)
    table.cell(infoTable, 0, 1, "SuperTrend", text_color=color.black)
    table.cell(infoTable, 1, 1, str.tostring(supertrend, "#.##"), text_color=color.black)

This is just one example. Generate any indicator or strategy you can imagine.

"I'd wasted weekends on free SuperTrend scripts that errored out or repainted, and freelancers quoted $200+ for fixes. Told HorizonAI 'SuperTrend buy sell with alerts and volume filter'—got perfect code in 25 seconds, compiler confirmed no issues. Now alerts hit my phone on flips, nailed two 5% moves last month."
