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.

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.
