Supertrend
Supertrend is a popular ATR-based trend-following indicator: a single line that sits below price and turns green in an uptrend, flips above price and turns red in a downtrend, and acts as a built-in trailing stop. This article explains how it is built from ATR bands, how to read its colour and flips for trend and entries, the role of the ATR multiplier and period settings, and its shared weakness with other trend tools — whipsawing in ranges.

Parabolic SAR
The Parabolic SAR (stop and reverse) plots a trailing series of dots above or below price that follow a trend and flip when it reverses. This article explains how the dots mark trend direction, act as a dynamic trailing stop, accelerate as a trend extends, and signal an exit or reversal when price crosses them — plus its key weakness of whipsawing in sideways markets and why it pairs well with a trend filter like ADX.
ADX & DMI
The Directional Movement Index (DMI) and Average Directional Index (ADX) are Wilder's tools for measuring trend direction and, crucially, trend strength. This article explains the +DI and -DI lines (which side is winning), the ADX line (how strong the trend is, regardless of direction), the conventional 25/20 thresholds for trending versus ranging, how DI crossovers signal direction, and how to use ADX as a filter rather than a standalone signal.
