Pine Script is a powerful domain-specific language created by TradingView for writing custom technical analysis indicators and strategies. If you are looking to visualize price levels on your trading charts using Pine Script, this article will guide you through the process. We will explore how to display prices, their significance, and provide practical examples.

What is Pine Script?

Pine Script is a versatile scripting language that allows traders to develop custom indicators, alerts, and strategies for various financial markets. The ability to manipulate price data and visualize it effectively is crucial for making informed trading decisions.

Why Show Price on Your Charts?

Displaying price levels on your charts can enhance your trading strategies by:

Identifying Support and Resistance Levels: Highlighting key price levels can help you understand where the market may reverse or continue its trend.
Making Visual Analysis Easier: By marking specific price points, you can quickly reference significant prices while performing technical analysis.
Enhancing Custom Indicators: Creating indicators that include price levels can provide more context and improve their functionality.

How to Show Price in Pine Script

To display price levels in Pine Script, you can use the label function to plot price points or lines on the chart. Below is a step-by-step example:

Example Code to Display the Current Price

//@version=5
indicator("Current Price Display", overlay=true)

// Get the current price
currentPrice = close

// Create a label displaying the current price
label.new(bar_index, currentPrice, text=str.tostring(currentPrice), style=label.style_label_down, color=color.green, textcolor=color.white, size=size.small)

Breakdown of the Code

Indicator Declaration:
- indicator("Current Price Display", overlay=true) defines the script as an indicator that overlays on the main price chart.
Fetching Price Data:
- currentPrice = close retrieves the most recent closing price.
Creating the Label:
- label.new(...) creates a new label on the chart. The parameters specify the position, content, style, and colors of the label.
- bar_index ensures the label is placed at the current bar, and currentPrice determines its vertical position.

Practical Applications

Example of Displaying Support and Resistance Levels

To take it a step further, you might want to display support and resistance levels along with the current price. Here’s how you can do it:

//@version=5
indicator("Support and Resistance Levels", overlay=true)

// Example static levels for demonstration
supportLevel = 100
resistanceLevel = 150

// Current price
currentPrice = close

// Create labels for support and resistance
label.new(bar_index, supportLevel, text="Support: " + str.tostring(supportLevel), style=label.style_label_up, color=color.red, textcolor=color.white, size=size.small)
label.new(bar_index, resistanceLevel, text="Resistance: " + str.tostring(resistanceLevel), style=label.style_label_down, color=color.blue, textcolor=color.white, size=size.small)

// Display current price
label.new(bar_index, currentPrice, text="Current Price: " + str.tostring(currentPrice), style=label.style_label_down, color=color.green, textcolor=color.white, size=size.small)

Explanation of the Extended Code

Static Levels: We defined static support and resistance levels (supportLevel and resistanceLevel), which can also be dynamically calculated using various methods such as pivot points or the highest/lowest prices over a certain period.
Multiple Labels: Labels are created for both support and resistance levels, in addition to the current price. Each label has a distinct color and positioning to differentiate between them visually.
