Best free TradingView indicators by task
Start with TradingView's built-in EMA for trend, RSI for momentum, OBV for volume context, or ATR for volatility. These are free starting points with documented calculations, not a ranking by returns. Choose the measurement your rules need; a paid script is not required to begin.
Top Picks Compared
Compare the rules and limitations below. Inclusion does not establish performance on your market or timeframe.
| Indicator | Best For | Repainting / Confirmation | Source Code | Notes |
|---|---|---|---|---|
| Exponential Moving Average (EMA) | Trend direction and smoothing price | The current value moves with its price source until the bar closes. | Built-in; use the source icon where available. | Choose the TradingView built-in Exponential Moving Average in Technicals. It weights recent prices more heavily. A shorter length reacts faster but can produce frequent crosses in a range. EMA is a lagging measurement, not a forecast. Source: TradingView EMA documentation below. |
| Relative Strength Index (RSI) | Momentum and overbought or oversold context | The current value changes with price; divergence labels have separate confirmation rules. | Built-in; the official guide also documents the calculation. | Choose the built-in Relative Strength Index. Its 0 to 100 scale describes recent price momentum. A value above 70 or below 30 does not establish a reversal or an entry on its own. Evaluate the RSI line separately from optional divergence signals. Source: TradingView RSI documentation below. |
| On Balance Volume (OBV) | Comparing cumulative volume with price direction | The current bar's price and volume can change before close. | Built-in; the official guide documents its cumulative rule. | Choose the built-in On Balance Volume. It adds volume when the close rises and subtracts it when the close falls. Use it only when the selected symbol supplies meaningful volume data. It is not bid/ask delta, a footprint chart, or a direct measure of institutional orders. Source: TradingView OBV documentation below. |
| Average True Range (ATR) | Measuring volatility in price units | The current range and ATR can change while the bar develops. | Built-in; the official guide documents true range and smoothing. | Choose the built-in Average True Range. It measures price movement, including gaps, without indicating direction. It can supply a volatility input for a separately defined risk rule. A high ATR is not a buy signal, and an ATR multiple is not a guaranteed stop distance. Source: TradingView ATR documentation below. |
Why These Made the List
Exponential Moving Average (EMA)
Best for: Trend direction and smoothing price
Choose the TradingView built-in Exponential Moving Average in Technicals. It weights recent prices more heavily. A shorter length reacts faster but can produce frequent crosses in a range. EMA is a lagging measurement, not a forecast. Source: TradingView EMA documentation below.
Relative Strength Index (RSI)
Best for: Momentum and overbought or oversold context
Choose the built-in Relative Strength Index. Its 0 to 100 scale describes recent price momentum. A value above 70 or below 30 does not establish a reversal or an entry on its own. Evaluate the RSI line separately from optional divergence signals. Source: TradingView RSI documentation below.
On Balance Volume (OBV)
Best for: Comparing cumulative volume with price direction
Choose the built-in On Balance Volume. It adds volume when the close rises and subtracts it when the close falls. Use it only when the selected symbol supplies meaningful volume data. It is not bid/ask delta, a footprint chart, or a direct measure of institutional orders. Source: TradingView OBV documentation below.
Average True Range (ATR)
Best for: Measuring volatility in price units
Choose the built-in Average True Range. It measures price movement, including gaps, without indicating direction. It can supply a volatility input for a separately defined risk rule. A high ATR is not a buy signal, and an ATR multiple is not a guaranteed stop distance. Source: TradingView ATR documentation below.
What free, open-source and invite-only mean
Cost, source visibility and permission are different questions. TradingView's publication types describe access; none certifies profitability or non-repainting behavior. The shortlist above uses TradingView's own built-ins to avoid confusing similarly named community copies.
| Type | Use on a chart | Source and limits |
|---|---|---|
| Built-in indicator | Find the named tool under Technicals. | Many built-ins are free. A source-code icon indicates that code is available; do not assume every built-in exposes it. |
| Open-source community script | Free to use under TradingView's publishing rules. | Source is visible. Reuse and republication still require compliance with its license and TradingView rules. |
| Protected community script | Free to use under TradingView's publishing rules. | Source is hidden. You can change exposed inputs, not inspect the full implementation. |
| Invite-only script | The author must grant access; a payment may be required. | Source is hidden. An invitation is an access permission, not an assurance of quality. |
Choose one missing measurement
This is an editorial shortlist based on documented purpose, access and understandable limitations. No comparative backtest or live trading trial was performed for this page. The four entries cover different questions; their order does not imply performance.
- Need a trend reference? Start with EMA and define whether slope, price position or a crossover matters to your rule.
- Need momentum context? Start with RSI. Specify what action, if any, follows a threshold crossing before reviewing results.
- Need volume context? Try OBV after checking the symbol's volume field and data feed. Skip it if that input is unavailable or unsuitable.
- Need a measure of movement size? Use ATR with a defined timeframe. It does not choose a trade direction.
- Avoid adding all four simply because they are free. Keep a tool only if it changes a documented decision and fits your plan's indicator allowance.
Add the official version and inspect its behavior
Open Indicators, metrics, and strategies, select Technicals, and search the exact name. Start on standard candles with the chart timeframe. Record the symbol, exchange, session, timeframe and inputs so you can reproduce the view.
- If you want to edit code, hover over the indicator name and look for the source-code icon. Where present, open it and create a working copy. If the icon is absent, source is unavailable for that version.
- Separate the live value from a confirmed signal. EMA, RSI, OBV and ATR can all change on the current bar as their inputs update.
- For a community replacement, inspect any higher-timeframe data requests, pivot confirmation and plots placed on earlier bars. Open source makes inspection possible; it does not make the logic correct.
- Observe signals live, save timestamps, and compare after reload. Replay is useful for historical inspection but cannot by itself prove that intrabar signals never changed.
- If you turn a measurement into a strategy, define entries, exits and costs before testing. Evaluate a separate period and record losing trades as well as winners.
When customization is worth considering
Use the free built-ins first. If you later need a particular combination of conditions or alerts, the Pineify Visual Pine Script Editor is a separate route for building custom logic. Pineify Premium Scripts is a paid collection to evaluate separately; its source access does not make it a free indicator recommendation. Check current product terms and test the resulting rules before relying on them.
