ATR Indicator Guide: The Most Useful Number in Risk Management
ATR does not tell you direction. It tells you how much an instrument typically moves, which is what determines stop distance and position size.
Indicators are not predictions. They are compressions of price and volume history. These guides show the maths in plain English, then turn each indicator into testable rules.
No prior knowledge assumed. Start here.
ATR does not tell you direction. It tells you how much an instrument typically moves, which is what determines stop distance and position size.
MACD is the difference between two moving averages. Understanding that makes its signals obvious and its limitations unavoidable.
The crossover is the most tested rule in trading. It works modestly, in the right conditions, with the right portfolio around it.
Moving averages are the most useful and most misused indicator. Their real value is as a regime filter, not as a source of entry signals.
RSI measures the ratio of recent gains to recent losses. Treating extremes as reversal signals without a trend filter is the most common way to lose money with it.
Supertrend is an ATR trailing stop that flips direction. Understanding that removes the mystery and clarifies exactly what it can and cannot do.
Every indicator is a transformation of price and volume. None contains new information. Knowing what each one measures prevents most indicator mistakes.
Assumes you know order types, charts, and basic risk sizing.
ADX answers the question most indicators cannot: is there a trend at all? That makes it a filter rather than a signal.
Bollinger Bands measure how far price has moved relative to its own recent volatility. A band touch is a measurement, not a signal.
A Donchian channel is the highest high and lowest low of the last N bars. It is the simplest possible trend definition and remains one of the most robust.
Fibonacci levels are popular, easy to draw, and difficult to test, because the choice of swing points determines the answer.
Ichimoku packages trend, support, and momentum into one overlay. Its strength is completeness; its weakness is that five correlated lines look like five confirmations.
Keltner Channels use ATR rather than standard deviation, which makes them smoother and better suited to trend riding than to reversion.
Pivot points are computed from yesterday and never move. That objectivity is their main advantage over hand-drawn levels.
The stochastic measures where price closed within its recent range. In a trend it pins at an extreme, which is information about strength, not exhaustion.
Volume measures participation, not direction. Every trade has a buyer and a seller, which rules out most of what volume indicators are claimed to show.
VWAP is the average price weighted by volume. It matters because large institutional orders are benchmarked against it, which makes it a genuine reference point.
