One candle = one time period
A candlestick shows open, high, low, and close (OHLC) for a chosen timeframe (1 minute, 1 hour, 1 day, etc.).
- Body — range between open and close.
- Wicks (shadows) — extremes reached during the period.
- Green/white candle — close higher than open (bullish period).
- Red/black candle — close lower than open (bearish period).
Candlesticks were popularised for rice trading in Japan and are now standard on TradingView, MT5, and most platforms. They help visualise sentiment within each bar — but single candles alone are not reliable “signals.”
