Every colourful line, wavy band, or scrolling histogram you’ve ever seen layered on top of a stock chart is, underneath, the same basic thing: a calculation. This lesson opens Module 5 - the biggest module in this course - by explaining exactly what an “indicator” is, the two broad families they fall into, and how to add or remove one on TradingView, before the following eight lessons work through specific indicators one at a time.
What Is an Indicator, Exactly?
An indicator is a mathematical calculation applied to a stock, index, or contract’s price and/or volume data, then plotted visually on a chart. Some indicators are quite simple under the hood - a moving average, for instance, is just an average of recent closing prices. Others involve a few more steps. But every indicator shares the same basic job: take numbers that already exist (past and current price, and sometimes volume), run a calculation on them, and draw the result so it’s easier to study at a glance than scrolling through a table of raw figures.
It’s worth being precise about what that means in practice. An indicator does not introduce any new information about a stock that wasn’t already present in its price and volume history - it simply re-presents that existing information in a way many traders find easier to read and compare over time.
Two Broad Families: Overlays and Oscillators
Nearly every indicator on TradingView falls into one of two broad categories, based on where it’s drawn.
Overlay indicators are plotted directly on top of the price chart, sharing its price scale. Moving averages, Bollinger Bands, VWAP, and SuperTrend (all covered later in this module) are overlays - each one draws a line or band right alongside the candlesticks.
Oscillator indicators are plotted in their own separate panel, usually below the main price chart, often on a fixed scale (commonly 0 to 100). RSI and MACD (also covered in this module) are oscillators - they need their own space because their values don’t share the same scale as price itself.

└───────────────────────────────────────┘Neither family is “better” - they answer different kinds of questions. Overlays tend to describe price itself (where is the average, where is a band of typical movement), while oscillators tend to describe momentum, speed, or extremity of a recent move.
Adding and Removing an Indicator on TradingView
Adding an indicator takes only a few steps:
- Open any chart and look for the “Indicators” button near the top toolbar (sometimes shown as an “fx” icon).
- Search for an indicator by name - for example, typing “Moving Average” or “RSI.”
- Select it from the list, and it’s applied to the current chart immediately - as an overlay or in its own new panel, depending on the type.
- Each applied indicator appears in a small list, usually near the top-left of the chart, where its settings (a gear icon) or removal (an “x”) are both one click away.
Nothing here is permanent. An indicator can be added, adjusted, or removed as many times as needed, and experimenting with a new one costs nothing but a few seconds.
Why Indicators Exist - and What They Don’t Do
Indicators exist because raw price alone can be genuinely hard to interpret quickly - especially across a busy watchlist of Nifty 50 stocks or several Bank Nifty options at once. A moving average can help a trader see a broader trend more easily than eyeballing hundreds of individual candles. A volatility indicator can help size a stop-loss more sensibly than guessing a fixed number of points.
But it’s just as important to be clear about what indicators are not. Every indicator, however popular, is calculated from past and current price and volume data - never from information about the future. Many traders use a given indicator to help spot a pattern, a shift in momentum, or a change in volatility worth investigating further - but no indicator, on TradingView or anywhere else, guarantees what a stock or index does next.
What This Module Covers
Across the next eight lessons, this module introduces:
- EMA and SMA (Lesson 19) - the two common flavours of moving average
- VWAP (Lesson 20) - an intraday, volume-weighted average price
- RSI (Lesson 21) - a momentum oscillator measuring the speed of recent price moves
- MACD (Lesson 22) - a trend and momentum indicator built from moving averages
- Bollinger Bands (Lesson 23) - a volatility-based band around a moving average
- SuperTrend (Lesson 24) - a trend-following overlay popular among Indian intraday traders
- ATR (Lesson 25) - a pure volatility measurement often used for stop-loss sizing
- Volume (Lesson 26) - the histogram showing how much trading activity backed a move
Real-Life Example: A Trader Adding Their First Indicator
Suppose a trader has just opened a Reliance Industries chart on TradingView, having spent the previous module practising trend lines and Fibonacci retracements. Curious about moving averages, they click “Indicators,” search “Moving Average,” and select it. A single line appears directly on the price chart, overlaying the candlesticks - not in a new panel, because a moving average is an overlay indicator. They then add RSI out of curiosity, and this time a completely new panel opens below the chart, with its own 0-to-100 scale. Nothing about the chart itself changed - only two additional layers of calculation, each drawn where it makes sense to draw it.
Analogy: A Doctor’s Diagnostic Instruments
Think of indicators like a doctor’s diagnostic tools - a thermometer, a blood pressure cuff, a stethoscope. Each one takes something already true about a patient’s body right now and displays it in a more useful form: a number, a reading, a rhythm. None of these instruments predicts what will happen to the patient next week; they simply describe the current and recent state clearly enough that a trained professional can make a more informed judgment. A trader’s indicators work the same way - describing recent and current price behaviour clearly, without ever promising what comes next.
Common Beginner Mistakes
- Adding too many indicators at once. A chart crowded with ten overlapping calculations is often harder to read than one with a focused one or two.
- Treating an indicator as a prediction rather than a description. Every indicator is built from past and present data - none of them see the future.
- Not knowing whether an indicator is an overlay or an oscillator, and being confused when it opens a new panel instead of drawing on the price chart (or vice versa).
- Forgetting that indicators can simply be removed. There’s no need to keep an indicator that isn’t proving useful just because it was already added.
Practical Tips
- Start this module by adding just one indicator at a time to a familiar chart (Nifty 50 or a stock you know well), rather than adding several simultaneously.
- Get comfortable with the “Indicators” menu and the small per-indicator settings/removal controls early - this same workflow is reused for every indicator in this module.
- Keep the overlay-versus-oscillator distinction in mind as you move through the next eight lessons - it explains why some indicators appear on the price chart and others open their own panel.
Practical Exercise
- Open a Nifty 50 or Reliance chart on TradingView, click the "Indicators" button near the top of the chart, and add any one indicator (try searching "Moving Average") just to see how it appears - then remove it using the same menu.
- Add one overlay indicator and one oscillator indicator to the same chart, and notice where each one is drawn - directly on top of the price versus in its own separate panel below.
Mini Quiz
1. What is a TradingView indicator, most accurately described?
An indicator is a calculation, often a fairly simple one, applied to a stock or index's price and/or volume history, then plotted so a trader can study it more easily than reading raw numbers off a table.
2. What is the key difference between an "overlay" indicator and an "oscillator"?
Overlay indicators, like moving averages, sit directly on top of the price chart, sharing its price scale. Oscillators, like RSI, are drawn in their own panel below the chart, frequently on a fixed scale such as 0 to 100.
3. Where on TradingView do you add a new indicator to a chart?
TradingView's "Indicators" button opens a searchable library of built-in indicators. Selecting one adds it to the current chart, and it can be adjusted or removed again from that same chart at any time.
4. Can an indicator be removed from a chart once it has been added?
Every indicator applied to a chart appears in a small list, usually near the top-left corner of the chart, and each entry can be individually adjusted or deleted whenever a trader wants.
5. What is the most important limitation to keep in mind about any indicator?
Every indicator, no matter how popular, is built from historical and current price/volume data. Many traders use indicators to help spot patterns worth investigating further, but none of them guarantee what price does next.
6. Roughly how many indicators does this module cover, and what areas do they span?
This module walks through eight commonly used indicators - EMA/SMA, VWAP, RSI, MACD, Bollinger Bands, SuperTrend, ATR, and Volume - each describing a different aspect of price or volume behaviour.
Frequently Asked Questions
Do I need a paid TradingView plan to use indicators?
No - a substantial number of indicators, including every single one covered in this module, are available on TradingView's free plan. Paid plans mainly increase how many indicators can be applied to one chart simultaneously, among other conveniences.
How many indicators should a beginner use at once?
There's no fixed rule, but many traders find that piling on numerous indicators at once creates more confusion than clarity. Starting with one or two, and understanding them thoroughly, is a far more common approach than adding everything available.
Are overlay indicators "better" than oscillators, or the other way around?
Neither is inherently better - they answer different questions. Overlays like moving averages describe price directly, while oscillators like RSI describe the momentum or speed of a move. Many traders use one of each together, for complementary views.
Can the same indicator be applied more than once to a single chart, with different settings?
Yes. For example, two moving averages with different periods, say 20 and 50, can both be applied at the same time, which is exactly how many crossover approaches work, as the next lesson explains.
Do indicators work the same way on Futures and Options charts as on stock charts?
Yes. Since indicators are calculated from price and volume data, they apply the same way regardless of whether the underlying chart is a stock, an index, a Futures contract, or an Option contract with available price history.
What happens if an indicator is added and a trader decides they don't like it?
Nothing is permanent. Every indicator can be removed from a chart in a couple of clicks, and adding it again later takes just as little effort - there's no risk in experimenting.
Is it possible to build a custom indicator on TradingView?
Yes, using Pine Script, TradingView's own scripting language, covered later in this course starting around Module 10. Nothing in this current module requires any coding at all.
Do professional traders rely only on indicators to make decisions?
Rarely in isolation. Most experienced traders combine indicators with plain price action, support and resistance levels, and their own risk management rules, rather than treating any single indicator as a standalone decision-maker.
Why does this module cover eight indicators instead of just one "best" one?
There isn't a single indicator that works for every trader or every market condition. Trend, momentum, volatility, and volume each describe a different aspect of price behaviour, which is why this module spreads across all four categories.
Key Takeaways
- An indicator is a calculation applied to price and/or volume data, plotted visually so it's easier to study than raw numbers.
- Overlay indicators are plotted directly on the price chart; oscillators are plotted in a separate panel, often on a fixed scale.
- TradingView's "Indicators" button/menu is where any indicator is added, configured, or removed from a chart.
- Indicators are built from historical and current data - they describe the past and present, not a guaranteed future.
- Many traders combine a small handful of indicators rather than applying dozens to a single chart at once.
- This module works through eight commonly used indicators, spanning trend, momentum, volatility, and volume.
Conclusion
An indicator is nothing more mysterious than a calculation, run on price and volume data, plotted so a trader can study it visually instead of scrolling through raw numbers. With that foundation in place - along with the overlay-versus-oscillator distinction and how to add or remove an indicator - the next lesson starts the module's first specific indicator: the moving average, in both its simple and exponential forms.
