Stock Screener & Pine Script Editor

The Bottom Menu is a collapsible panel that sits directly below the chart canvas. Click any tab label to expand it upward, revealing its full interface. The panel can be resized by dragging its top edge, giving you as much or as little screen real estate as you need.

Each tab represents an entirely separate analytical engine. Understanding what lives in each tab prevents you from hunting through menus when you need to switch workflows.

The Stock Screener is arguably the most powerful free research tool available to Indian retail traders. It allows you to filter thousands of NSE and BSE listed stocks using a combination of fundamental metrics, technical indicators, and descriptive categories—all updating in real-time during market hours.

To access it, click the 'Stock Screener' tab in the Bottom Menu. The default view shows a table of all available instruments sorted by market capitalization. From here, you can begin layering filters to narrow down your universe.

A practical example: 'Show me all NSE stocks with a Market Cap above ₹10,000 Crore, a P/E ratio below 20, RSI between 30 and 40 (oversold), and price trading above the 200-day Simple Moving Average.' This single query combines fundamental value screening with technical momentum filtering, producing a highly focused list of undervalued stocks in a long-term uptrend that are currently pulling back to attractive entry levels.

TradingView doesn't limit screening to equities. The platform provides dedicated screener engines for every major asset class, each with filters tailored to that market's unique characteristics.

The Crypto Screener, for example, includes filters for 24-hour trading volume, circulating supply, market dominance percentage, and blockchain-specific metrics that don't exist in equity screeners. The Forex Screener provides filters for pip-based performance, swap rates, and currency pair correlation.

While screeners produce lists, Heatmaps produce visual maps. TradingView's Heatmap tool displays every stock in a market as a colored rectangle. The size of each rectangle represents market capitalization, and the color represents performance over your chosen timeframe (green for gains, red for losses, with color intensity reflecting magnitude).

This provides an instant, at-a-glance understanding of where money is flowing. If the entire IT sector is deep green while Banking is red, you immediately know there is a sector rotation underway—without reading a single number.

Heatmaps are available for Stocks, Crypto, and ETFs. You can filter by country (India), sector, and industry to drill down into specific segments of the market.

The Pine Script Editor is TradingView's integrated development environment for Pine Script v6—the platform's proprietary programming language designed specifically for financial analysis. Unlike Python or JavaScript, Pine Script is purpose-built for markets: every function, every data type, and every construct is optimized for working with price series, volume data, and indicator calculations.

The editor sits in the Bottom Menu and provides a full-featured coding environment: syntax highlighting with financial-specific keywords, intelligent autocomplete for all built-in functions (like `ta.rsi()`, `ta.macd()`, `strategy.entry()`), real-time error diagnostics that highlight issues before you compile, and runtime logging (`log.info()`) for debugging complex strategies.

One of the most powerful learning features: click the `{}` icon next to any built-in indicator's name on your chart to view its complete Pine Script source code. This allows you to study how professional indicators like MACD, Bollinger Bands, and Supertrend are actually constructed—and then modify them to create your own variants.

The built-in Stock Screener covers standard filters like P/E and RSI. But what if you need to scan for something hyper-specific—like 'All NSE stocks where the 9 EMA just crossed above the 21 EMA on the Daily chart, AND the RSI is between 50 and 60, AND the MACD histogram is positive for the first time in 5 bars'?

This is where the Pine Screener becomes indispensable. You write a custom Pine Script indicator that encodes your exact scanning logic, add it to your Favorites, and then apply it across an entire watchlist using the Pine Screener interface.

The Pine Screener scans every symbol in your selected watchlist against your custom indicator's conditions, producing a filtered list of instruments that meet your algorithmic criteria. This is the closest thing to a fully custom, institutional-grade stock scanner available for free.

When you write a Pine Script `strategy()` instead of an `indicator()`, the Strategy Tester tab in the Bottom Menu comes alive. It executes your buy/sell logic against the entire historical dataset of the current chart, producing a comprehensive performance report.

The Strategy Tester displays four key sub-tabs: (1) Overview—showing Net Profit, Profit Factor, Max Drawdown, and Sharpe Ratio. (2) Performance Summary—breaking down long vs. short trade statistics. (3) List of Trades—a chronological record of every simulated entry and exit with timestamps and P&L. (4) Equity Curve—a visual graph of your account balance over time.

This is the engine that allows you to test hypotheses before risking real capital. If your strategy shows a negative Profit Factor or a Max Drawdown exceeding 20%, you know to iterate on the logic before deploying it live.

The Chart Range selector sits at the very bottom of the chart, providing predefined zoom presets: 1D, 5D, 1M, 3M, 6M, YTD, 1Y, 5Y, and All Time. Clicking any button instantly adjusts your chart's visible range to fit that exact period.

The 'Go to Date' feature (shortcut: `Alt+G` on Windows, `Option+G` on Mac) opens a calendar dialog that teleports your chart to any specific historical date. This is essential for studying price reactions to known macro events—Budget Day, election results, RBI rate decisions, or COVID crash dates.

Instead of endlessly scrolling backward through years of data, you type '2020-03-23' and instantly land on the exact candle where Nifty hit its COVID low. From there, you can begin your analysis, draw levels, and test hypotheses.
