Options will allow you to select to show Hammers, Engulfing or Harami patterns only. You choose the combinations that you want. Great tool to learn and training your eyes to the patterns.
You also have an option to select "Super" versions of the Engulfing and the Harami patterns, the Supers only shows if the pattern engulfs the body and the wick of the smaller candle in the pattern.
The indicator will show Bullish opportunities and Bearish opportunities on the chart for each of the patterns. The inverted hammer will show at the top indicating a Bear move, and the Hammer will show below price indicating a Bullish move.
Use this indicator in conjunction with other Support & Resistance such as the simple moving averages, trend lines, flat lines, or even Bollinger bands. When these patterns show at or around these points on the chart they will indicate a reversal is pending. Wait for the next candle as confirmation that the move will actually take place in the direction indicated and you will have your pivot point on the chart and create a higher probability of success. Leverage Stochastic, RSI, or CCI indicators to help confirm the reversal as well. Look out for resistance above or support below to determine your targets for the reversal.
