Plot Signals on TradingView Chart

To plot custom signals (e.g., buy/sell arrows) on a TradingView chart, you can use Pine Script, TradingView’s built-in scripting language. Below is a step-by-step example to plot signals based on a moving average crossover strategy:

Pine Script

The following Pine Script creates basic buy and sell signals based on a Simple Moving Average (SMA) Strategy:

//@version=6
indicator("MA Crossover Signals", overlay=true)

// Define Moving Averages
fastMA = ta.sma(close, 50)
slowMA = ta.sma(close, 200)

// Plot MAs on the chart
plot(fastMA, "Fast MA", color=color.blue)
plot(slowMA, "Slow MA", color=color.red)

// Define Conditions
buySignal = ta.crossover(fastMA, slowMA) // Fast MA crosses above Slow MA
sellSignal = ta.crossunder(fastMA, slowMA) // Fast MA crosses below Slow MA

// Plot Signals on the Chart
plotshape(buySignal, title="Buy", style=shape.triangleup,
 location=location.belowbar, color=color.green, size=size.small,text="BUY")
plotshape(sellSignal, title="Sell", style=shape.triangledown,
 location=location.abovebar, color=color.red, size=size.small,text="SELL")

 

How It Works?

Explanation of the script:

• Moving Averages
  • A 50-period (fast) and 200-period (slow) SMA are calculated.
  • These are plotted as lines on the chart.
• Signal Conditions
  • Buy Signal: When the fast MA crosses above the slow MA.
  • Sell Signal: When the fast MA crosses below the slow MA.
• Visualization
  • Green ▲ triangles appear below bars for buy signals.
  • Red ▼ triangles appear above bars for sell signals.
