Long — meaning in trading

Where this comes up

Lessons that use the term in context, which is usually more useful than the definition on its own.

One candle holds four numbers — Open, high, low, close — and why the wick does more work than the body.
Volume behind the move — Participation, read underneath price.
Range compression — What narrowing ranges say, and what they do not say.
The failed breakout — Closes, not wicks — and the difference between a poke and a break.
