Engulfing pattern

As explained in Investing for Programmers

An engulfing pattern is a candlestick pattern in which a large candle completely contains the preceding candle and signals a substantial momentum shift.

An engulfing pattern is a candlestick formation in which a large candle completely contains the preceding candle, indicating a substantial shift in momentum. section 10.2.1

Read the pattern alongside candlestick anatomy:

  • Compare consecutive candles rather than interpreting one trading day in isolation. section 10.2.1
  • Use body size and wick behavior as context: large bodies indicate strong momentum, while long wicks indicate price-level rejection. section 10.2.1
  • Treat the engulfing label as a way to describe a substantial momentum shift, not as a complete market analysis. section 10.4

Chart inspection

Plot daily OHLC data as candles, then inspect adjacent candles for a large candle that fully contains the prior one. Compare the result with other named patterns such as Doji and Hammer. section 10.2.1

Figure 10.20 Various candlestick patterns in which we can describe the behavior of the market. In addition to the Doji, Hammer, and Engulfing patterns, we can see the volatility of prices. You immediately realize that candles with long bodies represent high volatility, whereas candles with multiple short bodies represent a calm market situation.
