This post is presented as an alternative method for finding candles presented here:

PCFs and EasyScans for Candlestick Patterns

Each PCF is one Boolean formula and self-contained. You will want to sort the results of your EasyScans by a price performance criterion to be sure the stock is trending the right way (if the pattern requires a trend).

Each pattern has one PCF. If you add that pattern’s PCF to an EasyScan you will limit the stocks to those that meet the requirements.

You can visually back test these patterns using the PCF for the pattern in the procedure taught in this video:

Craig,How can we put maybe the bullish candle patterns as one indicator and the Bearish Candles one indicator?Also how can a formula be written that will lable the candle when it pops up on the chart when it is identified by the indicator?You seem very knowledgeable about candlestick patterns and formulas for them.Eager to hear your response.

You could OR all of the formulas together to make it one big formula, but it might be hard to figure out which pattern resulted in the True indication.

We don't have way to create formula-based chart labels.
