Technical Indicators: Where to Start
Technical indicators are best learned from the base up: first how to test whether one works at all, then the moving average most of them are built from, then the momentum oscillators, then volatility and volume. The last step is choosing a set that does not measure one thing twice.
Most indicator education starts with a favorite and works outward. This path starts with the one question that decides whether any indicator deserves a place on the chart, then builds the family up from the average almost all of them are made from.
The reading path
- Do Trading Indicators Actually Work? The question to settle before any indicator: does it beat a control, and how would you know.
- What Is a Moving Average? The building block. Most of what follows is an average of something, so this comes first.
- Exponential Moving Average: Not Faster What weighting recent bars more heavily changes, and what it leaves exactly the same.
- What Is MACD? Two exponential averages subtracted, which makes it a trend tool that misbehaves in a range.
- What Is RSI (Relative Strength Index)? The first momentum oscillator, and why a reading of 70 is not an instruction to sell.
- What Is the Stochastic Oscillator? Where the close sits inside the recent range, and why overbought is what an uptrend looks like.
- What Are Bollinger Bands? The move from direction to volatility: a band that widens and narrows with how much price moves.
- What Is ATR (Average True Range)? Volatility with no direction in it at all, and its real job, which is sizing stops.
- What Is VWAP? The one common line whose input is not price alone, because volume is weighted into it.
- How to Choose Which Indicators to Use How to pick a set by what each one measures, rather than by which one looks best on a chart.
- Confluence: When Four Reasons Are Really One When four reasons pointing at one price are really one reason counted four times.
How to read this path
The first page is a test, and everything after it is a candidate for that test. Reading the indicator pages first and the test last is how people end up defending a tool they never checked. With the test in hand, every later page can be read with one question: what would this have to beat?
Pages two to four are one family. A moving average, its exponential version, and MACD are the same arithmetic at increasing levels of processing. MACD is not a separate idea from the moving average; it is two of them subtracted, with a third average drawn over the result. Learning them in sequence makes that visible instead of mysterious.
Pages five and six are momentum. RSI and the stochastic are both oscillators that report a number between 0 and 100 from recent closing prices, and both are routinely misread at their extremes. They are next to each other so the similarity is obvious before the choosing page asks whether you need both.
Pages seven to nine change the input. Bollinger Bands and ATR measure how much price is moving rather than which way, and VWAP brings in volume. These are the pages that add genuinely different information to a chart built from momentum readings.
The last two pages are about the set, not the tools. They cover how to combine indicators without counting the same evidence twice, which is where most indicator-heavy charts go wrong.
A worked example
The arithmetic behind three of these tools fits in a few lines, and seeing it removes most of the mystery.
MACD. Say the twelve-period exponential average of the close is 101.20 and the twenty-six-period average is 100.50. The MACD line is 101.20 minus 100.50, which is 0.70. If the nine-period average of the MACD line, the signal line, is 0.55, the histogram is 0.70 minus 0.55, which is 0.15. A histogram shrinking toward zero means the two averages are converging. It says nothing about the future.
RSI. Over fourteen bars, suppose the average gain on up bars is 1.20 and the average loss on down bars is 0.80. The ratio is 1.20 / 0.80 = 1.5, and RSI = 100 − 100 / (1 + 1.5) = 60. A reading of 60 says recent gains were half as large again as recent losses. That is a description of the last fourteen bars, which is why it can stay high for a long time in a trend.
Bollinger Bands. With a twenty-bar average of 50.00 and a standard deviation of 1.50, the bands sit two deviations either side: 50.00 ± 3.00, so 47.00 and 53.00. When the deviation doubles, the bands double in width. The bands measure spread, not direction.
All three numbers are hypothetical inputs chosen to show the formulas. Each linked page works the same arithmetic on its own example.
The original data
Indicators are among the most covered subjects in trading video titles, and among the weakest performing. In the site’s study of 24,971 YouTube trading videos, 1,937 titles contain the word indicator or indicators, from 927 channels, with a median of 8,753 views. The median video across the whole study has 10,684.
The most-named tools sit furthest below that median. RSI or relative strength index appears in 594 titles with a median of 5,377 views, and MACD in 471 titles with a median of 3,645. Moving average, EMA or SMA titles number 651 with a median of 6,868; Bollinger titles 268 with a median of 4,842; VWAP titles 322 with a median of 6,592.
The less-covered tools do better. The stochastic appears in 184 titles with a median of 11,915 views, and ATR or average true range in 146 with a median of 11,250, both above the study’s median. Across all of these names, 3,768 videos, 15.1% of the study, name at least one indicator in the title. Counts are unique videos whose title contains the phrase as whole words, with views as displayed in August 2026.
When it fails
Indicators built from the same closes agree with each other, and agreement is not evidence. RSI, the stochastic and MACD are all computed from recent closing prices. When all three point the same way it usually means price moved, which you could see without any of them. The choosing and confluence pages at the end of this path exist because stacking them is the most common way this goes wrong.
Every indicator has a market it fails in. Trend tools like MACD and moving average crossovers give repeated false signals in a range. Oscillators like RSI read as overbought for bar after bar in a strong trend. Reading the pages in order shows each tool’s failure case next to its definition, and the failure case is the part to remember.
Tuning the settings on past data finds a fit, not an edge. Changing a length from 14 to 11 because it worked better last year is fitting noise. The overfitting page explains why each adjustable setting is another way to describe the past, and why a result that needed tuning should be tested on data it never saw.
This path does not include every indicator on the site. It covers the core family. The glossary holds dozens more, and most of them are variations on the averages, oscillators and ranges covered here.

Chart reading without any indicator is covered by the smart money concepts path, which works entirely from swing points and levels. However a signal is generated, the size of the position is a separate decision, and the risk management path covers it in order. If the RSI page is where you want to go deeper, how to use the RSI turns the definition into a procedure for trends and ranges separately.
