Advanced Candlestick Patterns [vitruvius]

By vitruvius
This is a very advanced indicator that detects most commonly used candlestick patterns. Please read this document carefully to understand how it works.

It is tailored to identify patterns that only have a great possibility of signaling a price movement. In other words, it can and will ignore some patterns, even though they satisfy the recognition conditions defined in the books. Candlestick patterns should also satisfy some other conditions in this indicator to be valid and you can modify those conditions.

This indicator is not only about identifying the candlestick patterns. By using the different choices, you can:
  • Avoid fake signals
  • Confirm patterns
  • Increase your possibility to win a trade
  • Reduce risk
  • Identify bullish/bearish movements better


Recommended Use
This indicator works best when you:
  • Use it in the daily time frame
  • Combine it with Support/Resistance areas


Note: For some candlestick patterns, you have the option of confirming the pattern with the next price action. In those cases, there will be obviously one bar delay (because it will wait for one more bar to close to confirm the pattern). However, it will mark the candlestick where it identifies the pattern and it will have ”Confirmed” in its text.

Important Note
This indicator does some serious calculations and checks for a lot of user inputs. Therefore, it might be a little slow. Please give it some time when it needs to do some computing.


MODULES

Trend Detection
Most of the patterns in this script are trend reversal patterns. So, recognition of the candlestick patterns depends heavily on the trend. In fact, even if you do not select a trend detection method, it will use the SMA method as default where it needs a certain trend in identifying a specific pattern.

It is possible to combine multiple trend detection methods. You can see how this affects the overall trend detection by enabling the background coloring.

Note: There might be some cases where a candle has a bullish/bearish confirmation of the same candlestick pattern. In those cases, the script is unable to identify the move and the user should decide if the identified pattern is bullish or bearish.

Below are the inputs of this module:
  • Color the background according to the trend?
    If you select a trend detection method, it will color the background green for an uptrend and red for a downtrend.
  • Counter the trend when there is no obvious trend?
    If you select multiple trend detection methods, there might be some cases where one of the methods indicates an uptrend and the other one indicates a downtrend. In that case, the script will continue with the previous trend (whatever the trend is one bar ago) by default. You can, however, reverse the trend in those cases by using this option. If you choose to reverse, you might catch the trend early.
  • Use MACD to detect the trend?
    Use MACD to detect the trend. Whenever MACD delta is greater or equal to zero, it is an uptrend.
  • MACD Fast Length
    Fast length of MACD.
  • MACD Slow Length
    Slow length of MACD.
  • MACD Signal Smoothing
    Signal smoothing value of MACD. Please note that it is set to 6 by default.
  • Use SMA to detect the trend?
    Use SMA to detect the trend. If the price closes above the SMA line, it is an uptrend
  • SMA Length
    Length of SMA.
  • Use the average price of previous candles to detect the trend?
    If the average of open and close prices constantly go up for n bars that are determined by the next user input, it is an uptrend.
  • Number of candles to analyze
    The number of bars (n) to analyze for the average price method.
  • Use the closing price of the previous candle to detect the trend?
    If the difference between the current close and nth previous bar’s close is greater than the given threshold, it is an uptrend.
  • Position of the previous candle to analyze
    Position of the bar (backward) to compare with the current close price.
  • Threshold for the closing price
    The threshold value for closing price method.


Basic Candlestick Patterns
This module detects Doji, Spinning Top, Marubozu candlestick patterns. Also, you can set some specific options that are going to be used in all candlestick patterns.

Note: If you choose to manually enter the body height of a doji, you need to find the optimal value for different timeframes. Different timeframes have difference price action ranges.

Below are the inputs of this module:
  • Tolerate opening/closing price of the candle?
    When a candlestick pattern needs to have a gap between two candles, you can tolerate the opening/closing prices of the one candle. This option is useful where the opening and closing prices are very close. This option is going to be used in all candlestick patterns.
  • Factor for tolerating opening/closing price
    The more the factor is, the more the tolerance is.
  • Body/Height ratio for a candle to be considered as Bullish/Bearish
    A bullish/bearish candle shouldn’t have too much shadow. You can use this option to determine the shadow length of a bullish/bearish bar. This option is going to be used in all candlestick patterns
  • Use basic candlestick pattern (Doji, Spinning Top, Marubozu)?
    Detect doji, spinning top, marubozu candlestick patterns.
  • Manually set body of Doji?
    You can manually set the body height of a doji. Otherwise, it will be calculated automatically. If you choose to use this option, then spinning top, and marubozu will also be calculated based on this.
  • Body of Doji
    Body height of a bar to be considered as doji. Any bar with a body equal or less than the given value will be marked as doji. Only effective if you check the ”Manually set body of Doji?” option.
  • Verify a Doji by looking at the preceding candle?
    If true, it will only mark dojis if the preceding candle is bullish or bearish.

Below are the inputs of this module:
  • Confirm Single Candlestick Patterns with next closing price?

  • Detect the Inside Bar only if the previous candle closes outside of the Keltner channel?
    This option effects identifying the inside bar. Such that, an inside bar will be detected only if the previous candle closes outside of Keltner Channel. Inside bars are effective when the market is extended and this is a nice way to check for that.
