Every candle on a chart squeezes four numbers into one shape: the open, the high, the low, and the close.
By the end of this lesson you'll be able to read all four off a single candle, and tell at a glance who won that period — buyers or sellers.

Candlestick charts came out of 18th-century Japanese rice trading and were popularised in the West by Steve Nison in the early 1990s. The format survived because it packs four numbers — open, high, low, close — into a shape you can read at a glance, which a line chart cannot.
A candle always represents a fixed slice of time. The same market drawn on a 5-minute and a daily chart produces completely different candles from identical price data, which is why "what does this candle mean?" is unanswerable without knowing the timeframe.
They contain identical information to a bar chart — the difference is purely visual. Most traders find bodies and wicks quicker to read at a glance, which is the only real advantage.
Higher timeframes are more forgiving because each candle takes longer to form, leaving time to think. Daily and 1H charts are a more sensible place to learn than 1-minute.
Brokers use different session close times and feeds, so daily candles can open and close at different moments. Levels drawn on one platform may not line up exactly on another.
