What the shape tells you
The body spans open to close and shows net direction. The wicks reach to high and low and show how far price travelled and was rejected. A long upper wick means buyers pushed up and could not hold it; a long lower wick means the reverse.
A body with almost no wicks means the interval trended cleanly. A tiny body with long wicks on both sides means a lot of movement and no resolution.
Timeframe changes the picture completely
A one-minute chart showing a dramatic reversal is a single candle on the hourly. Neither is more true; they answer different questions. Choosing a timeframe is choosing which movements you consider noise.
Reading a short timeframe and making a long-horizon decision is one of the most common errors, and it is a category error rather than a skill problem.
Patterns and what they are worth
Named formations describe shapes that recurred often enough to get names. Some have weak statistical support in some markets; most published results do not survive transaction costs and out-of-sample testing.
The honest framing is that a pattern is a description of what just happened, sometimes useful as context, never as a forecast.
Reading a crypto chart specifically
Crypto trades continuously, so there is no session open or close to anchor daily candles — the boundary is a timezone convention. Volume differs enormously between venues, and a candle from a thin venue describes that venue, not the market.
FBT Swap presents chart history and indicator readings with their window and source, and presents no formation as a signal to act.
