Trend

An indicator that measures the strength of a trend without saying anything about its direction. It answers a single question: is the market trending at all?

A measure of how recently the last extreme was made — a 'freshness gauge' for trends. Tushar Chande's unusual idea: read not the direction of price, but the youth of that direction.

The highest high and lowest low of the past N bars, drawn straight. No smoothing, no statistics — the oldest and simplest trend-following envelope, and the one the Turtles famously traded.

A fixed-percentage band wrapped around a moving average. Older than Bollinger Bands, simpler than Keltner — the most primitive of all channel indicators, and the one that refuses to bend with the market's mood.

Alan Hull's 2005 design folds two weighted moving averages together to suppress lag without surrendering smoothness — an attempt to reconcile two qualities that, mathematically, cannot both win.

A Japanese-born system that reads price, time, and trend in a single glance. Five lines and a cloud, designed to make the market's equilibrium visible at once.

An ATR-based envelope. Where Bollinger Bands measure the spread of consensus through standard deviation, Keltner measures the depth of the market's breathing through range.

Stop And Reverse — a mechanical trailing stop that follows a trend from behind and flips position the moment it ends. A row of dots that closes the window for hesitation.

An ATR-based trailing line that flips between above and below price. While the line holds, the trend's hypothesis is still alive — an indicator made of one visualised expiry date.

A 2010 indicator that borrows from fluid dynamics — measuring upward and downward motion as two separate currents, and reading the market by the direction in which the vortex is winding.

A moving average wrapped in a standard-deviation envelope. Squeeze, band-walk, the real meaning of ±2σ — and the worst misuse: 'fade the touch'.

A trend oscillator that graphs the 'difference' between two moving averages. Signal crosses, the zero line, divergence — how it works, and the lag trap everyone falls into.

The simplest tool and the most misused. How to draw trend lines correctly, what makes them valid, how to judge a break, and the trap of discretion.

The most fundamental trend indicator. Moving averages smooth out price data to visually reveal the direction of a trend.
