Lesson 24 of 28

The wider indicator toolbox: a categorized overview

There are hundreds of technical indicators, and new ones appear every year. The good news is that nearly all of them fit into a few main categories. If you know which question each tool answers, you do not need to learn them all. This lesson offers a map of the toolbox and a way to choose from it.

The category table

CategoryMain questionExamplesBest conditions
TrendWhat is the dominant direction?SMA, EMA, Ichimoku, Supertrend, Parabolic SARTrending markets
Trend strengthIs there a trend, and how strong is it?ADX, DMI, AroonFiltering which method to use
MomentumIs the move accelerating or slowing?RSI, Stochastic, MACD, CCI, Williams %RRanges and spotting divergence
VolatilityHow wide are price swings?ATR, Bollinger Bands, Keltner ChannelsRisk management and stop placement
VolumeHow much participation is behind the move?OBV, MFI, Chaikin Money Flow, VWAPMarkets with reliable volume data

Some tools sit on the border of two categories. MACD reflects both trend and momentum, for example, and MFI blends momentum with volume.

How to choose

  1. Start from your trading style. A trend follower needs trend and volatility tools; someone who trades ranges will lean more on oscillators.
  2. Consider the market. In forex and spot gold, volume data is incomplete; in crypto, higher volatility may call for different ATR settings.
  3. Few but deep. Two or three tools from different categories whose behaviour you know well are more useful than ten you know superficially.
  4. Test before using it for real. Check a tool on historical data and then on a demo account, and record the results honestly.

An important reminder

No indicator knows the future. They are all different representations of past price and volume. Their value lies in organising how we look at the market and helping us make more consistent decisions, not in guaranteeing outcomes. Even with the best combination of indicators, risk management remains the most important part of the job.

Key takeaways

  • Most indicators fall into trend, trend strength, momentum, volatility or volume.
  • Choose tools based on your trading style and the market you trade.
  • A few tools known deeply beat many tools known superficially.
  • Indicators are not a substitute for risk management.
