Plain English

A candle (short for candlestick) is a single visual bar on a price chart that summarizes price action over a specific time period — one minute, one hour, one day. It shows four data points: open, close, high, and low.

How it actually works

The body of the candle is the rectangle between the opening and closing price. If close is higher than open, the candle is typically green or hollow (bullish). If close is lower than open, it is red or filled (bearish). The thin lines extending above and below the body are wicks (or shadows), showing the high and low reached during the period. Stacked together across many periods, candles form a candlestick chart.

What it means for you

For traders, candles are the basic vocabulary. The shape, size, and sequence of candles tell you something about supply, demand, and sentiment. For long-term holders, they matter mostly as context — not signals to act on.

How ARCrypto teaches this

We teach candle reading as one input to market context, not as a trading edge by itself. The discipline: candles inform timing, not strategy.
