Engulfing candle Screener


The engulfing candle screener is looks for engulfing candles and produces a SELL or BUY signal if a engulfing candle is detected.

A engulfing candle is defined as one candle that engulfs the previous one. The screener can be configured to specify each of the characteristics of the engulfing candle and the engulfed candle.

In summary, an engulfing pattern may have the following characteristics:

  • It is the composition two candles C1 and C2.
  • C1 body is bigger than C2 body or;
  • C1 range (High-Low) is greater than C2 range (High-Low)
  • C1 sentiment is different than C2’s sentiment

As an example:

This screener will look for this pattern, as soon as a session closes.

Engulfing pattern recognition parameters

Because you can have multiple of ways to define what is the engulfing pattern, you can configure the screener to look for characteristics of each of the candles in the composition of two candles.

You can define how the wicks and bodies look like when analysing the pattern and you can specify if you want the engulfing candle to conform the Big Shadow concept, as defined inWalter Peters Ph.D. book Naked Forex.

Like the Wick Screener, this is also divided into two sub-screeners. One of the sub-screeners will look for Bearish engulfing and the other sub-screener is looking for Bullish engulfing patterns.
