Candlestick charts are the backbone of technical analysis. Originally developed by Japanese rice traders in the 18th century, they provide a visual representation of price action that reveals market sentiment at a glance.

Each candlestick represents four key data points: the open, high, low, and close prices for a given time period. The body of the candle shows the range between open and close, while the wicks (or shadows) show the high and low.

Essential patterns every trader should know:

Doji: When the open and close are nearly identical, forming a cross shape. This signals indecision in the market and often precedes a reversal.

Hammer: A small body at the top with a long lower wick. This bullish reversal pattern suggests buyers are stepping in after a decline.

Engulfing Pattern: When a candle completely engulfs the previous one. A bullish engulfing after a downtrend signals potential reversal, while a bearish engulfing after an uptrend warns of a possible decline.

Morning Star: A three-candle pattern consisting of a large bearish candle, a small-bodied candle (the star), and a large bullish candle. This is a strong bullish reversal signal.

Remember that no single pattern should be used in isolation. Always combine candlestick analysis with other indicators like volume, RSI, and moving averages for more reliable signals.
