1. Candlestick Anatomy: Decoding OHLC & Wick Rejections

Part of Chapter 05: Technical Analysis Foundations & Candlestick Anatomy

Core Learning Concepts
  • Open, High, Low, and Close (OHLC) auction dynamics
  • Body size as an indicator of aggressive market momentum
  • Upper and lower wicks as visible evidence of aggressive price rejection

Originating from 18th-century Japanese rice merchant Munehisa Homma, candlestick charts display four critical data points for any given time interval: the Open, High, Low, and Close (OHLC).

The solid candle body represents the final net price change between the open and the close. A tall, full-bodied green candle proves that aggressive market buyers dominated the entire session without facing substantial limit sell resistance.

The wicks (shadows) represent intra-session extremes where price pushed, encountered opposite liquidity, and was forcefully rejected. A long upper wick at a key resistance level reveals aggressive sellers stepping in to absorb buying volume, indicating potential exhaustion.

Institutional Execution Insight

Never trade a candlestick until the candle has officially closed. An intraday candle can look like a massive bullish engulfing with 1 minute remaining, only to turn into a long-wick shooting star right at the close.
