The Bullish Harmonics indicator will help you trade harmonic patterns with ease. It recognizes the twelve most favourable bullish harmonic patterns. It displays the figures with buy signals and price targets on your charts. The associated screener will help you discover trade opportunities in real-time.

Indicator Installation

Before installing the indicator, you must purchase a license or subscribe to the trial version. The indicator is available on the Prorealcode marketplace at this address:

https://market.prorealcode.com/product/bullish-harmonic-patterns-indicator-screener

Installing the indicator is a quick and easy process. Follow the standard installation procedure described on this page:

https://market.prorealcode.com/how-to-install-my-product-in-prorealtime

Launching the Indicator

After installing the license on your Prorealtime platform, the indicator will be available in the Indicators & Trading Systems window in the “ProRealCode MarketPlace” section.

To access the indicators window, click on the “Price” icon located in the price chart window, then on “Add Indicator…“:

To access the indicator, refer to the “ProRealCode MarketPlace” section or type the name “Bullish Harmonics” in the search bar. Double-click on the “Bullish Harmonics” indicator to display it in the price window:

Why does the price chart become flat after loading the indicator?

The indicator returns buy and sell signals. This allows you to use the indicator to create alerts and backtests. It returns 1 for buy signals and -1 for sell signals. These values ​​are displayed by default on the price chart. This automatically adjusts the chart size, making it flat.

To avoid having to readjust the price chart, follow these steps:

1. Double-click on the price chart
2. Open the indicator configuration window
3. Scroll to the bottom of the window
4. Uncheck the boxes in the “Line” column (which can be called “Signal”, “Breakout”, “Crossing”, etc.)

The price chart will readjust; you won’t need to repeat this action. If the problem persists, you can uncheck the stoploss and targets. The indicator already displays these.

Indicator Configuration

The Bullish Harmonics indicator is fully configurable. It offers numerous options that enable you to tailor the indicator to your specific needs. You can choose the type of harmonic patterns, display Fibonacci levels, allow buy signals to, apply filters, set price target levels, and change the display.

Accessing the Control Panel

To access the indicator control panel, click the indicator tab at the top of the price chart window and then click “Configure“:

The indicator configuration window will open and allow you to configure it according to your wishes:

Selecting Harmonic Patterns

You can select the type of harmonic patterns the indicator will look for on the price chart. To do this, check the corresponding box(es):

Pattern Size

The indicator uses an oscillator to identify peaks and troughs, thereby revealing harmonic patterns. You can set the oscillator’s period with the “Oscilator Period” parameter:

Buy Zone Length

When the indicator has identified a harmonic pattern, it plots buy zones and breakout lines to detect signals. You can set the length of the buy zones and breakout lines with the “Zone & Line Lengths” parameter:

Buy Signal Selection

The indicator detects buy signals specific to each pattern. It integrates several types of signals to help you adapt to each situation. You can open reversal, recovery, and uptrend continuation positions.

Here are the types of buy signals detected by the Bullish Harmonics indicator:

Bullish Reversal	Uptrend Resumption	Uptrend Continuation
Price in Buy Zone Breakout of Buy Zone Test of Buy Zone Breakout of Bottom Trendline Test of Bottom Trendline	Breakout of Top Trendline Test of Top Trendline	Breakout of Resistance Test of Resistance

You can select the types of buy signals by checking the corresponding box(es):

Here are some examples of buy signals detected by the Bullish Harmonics indicator:

Pattern Detection

You can display the moment a pattern is detected by checking the “Figure Detection” box. In this case, the indicator will consider the pattern detection as a buy signal:

Signal Validation

You can enable signal validation by checking the “Validated Signals” box. In this case, the indicator will only display validated signals.

Volume Filter

You can filter signals only if they are accompanied by volume. To do this, click the “with Volumes” option:

Divergence Filter

You can filter signals only if there is a bullish divergence. To do this, click the “with Divergence” option:

Trend Filters

You can filter signals according to the market trend:

• The “In the Trend” option only retains buy signals appearing in an uptrend.
• The “Reversal” option only retains buy signals appearing in a downtrend.

Price Target and Safety Stop

The indicator uses the pattern construction points to calculate Fibonacci ratios. These ratios will be used to define specific price targets.

• You can choose to display these levels by checking the “Take Profit” and “Stop-Loss” boxes.
• You can adjust these levels with the “TP Level” and “SL Level” parameters.

Fibonacci Levels

You can display the Fibonacci extensions associated with each harmonic pattern with the “Display Fibonacci Levels” option.

You can set the number of Fibonacci levels the indicator will display with the “Fibonacci Levels” option.

Display Options

The Advanced Bullish Harmonics indicator contains options that allow you to customize the indicator’s display:

Here is the list of options and their meanings:

mySignal, myTargetLong, myStopLossLong, myFibonacci, myP1, myP2, myP3, myP4, myP5 = CALL "Bullish Harmonics"[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 50, 50, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 1, 7, 1, 2, 1, 8, 50, 5, 14, 11, 2, 1, 3, 5, 1](close)

Indicator Returns

The Bullish Harmonics indicator provides all the information you need to backtest a strategy or create a trading robot. Here are the indicators’ returns and descriptions:

Data	Description
mySignal	Buy Signal
myTargetLong	Price Target Value
myStopLossLong	Safety Stop Value
myFibonacci	Value of the selected Fibonacci level
myP1, myP2, myP3, myP4, myP5	Value of the building points of the figures

Calling the indicator in a backtest

To call the indicator in a backtest, you must pass it its configuration parameters. I’ve created sample code to help you integrate the indicator into a strategy. The variable names are the same as those in the indicator.

The following code calls the Advanced Bullish Harmonics indicator. It will open long positions if a buy signal accompanied by volume is detected:

Harmonic Pattern Screener

The screener provided with the indicator will help you identify opportunities in real-time. You can detect the occurrence of the twelve bullish harmonic patterns recognized by the indicator, along with buy signals. You can apply them to predefined or custom lists, across all asset classes and all time frames.

Installing the Screener

The screener installation procedure is identical to that of the indicator. You will need to upload the license key to your Prorealtime platform.

To access the screener, follow these steps:

Open the ProScreener Window

Screener Results

After launching the screener, the discovered opportunities will appear in the results list. Simply click on a line to display it on the price chart:

Increase the number of opportunities

If the screener doesn’t return any results, it means that no stocks match your configuration. Here are some actions you can take to increase the number of opportunities found by the screener:

• Reduce the oscillator period
• Disable volume and strength filters
• Disable trend filters
• Choose large asset lists like the Nasdaq and NYSE
• Choose a lower timeframe

Note: ProScreener limits the historical access to 256 candles. As a consequence, you will not detect patterns exceeding this number of candles.
