Candle Body Support/Resistance [LuxAlgo]
The Candle Body Support/Resistance indicator is a tool that provides Support/Resistance levels from high-volatility candles, a concept originally described by Steve Nison in "Beyond Candlesticks".
Users can define the candle body percentage used to set the detected support/resistance levels. Occurrences of price testing the returned levels are highlighted using user-customizable dots.
🔶 USAGE
Support/Resistance levels are drawn from volatile candles, that is candles having a body (range between opening and closing price) whose magnitude is larger than the Volatility Threshold, which is determined by the multiplicative factor of an ATR (Average True Range) using a user set length.
The level starts from the opening price +/- a percentage of the open-close range. Users can adjust the percentage of the candle body used as support/resistance levels respectively, with higher percentage values returning levels prone to get reached sooner by the price.
A test is considered valid when a wick passes through the Support/Resistance level while the closing price is not breaking it.
Two modes are included, Trailing and Historical, both affecting the displayed elements of the indicator, these are described in the sub-section below.
🔹 Historical
The Historical Mode will draw a separate line from every Volatile Candle. When this line is tested, a dot will be drawn.
In the above example, the red resistance line was tested once until a bullish volatile candle formed, which closed just below the resistance level. The resistance level was tested again, after which the newly created support level was broken quickly, and the price decreased. These levels proved helpful later, acting as resistance/support levels (illustrated by the extra manually drawn dashed white lines).
To prevent cluttering Support/Resistance, lines will be deleted when the line is mitigated and hasn't been tested.
When a Support/Resistance line reaches its Maximum Line Length, it will also be deleted when it has not been tested.
🔹 Trailing
When a new volatile candle of the same type (bullish/bearish) appears while the Support/Resistance isn't broken, this line will be updated with the values of the new volatile candle. This creates a trailing line and a less cluttered chart.
Unlike the Historical mode, a line will not be deleted after a while or when it is mitigated. Instead, the line won't be updated anymore. A new line will start from the next found volatile candle.
Using the same situation as the Historical Mode example, we can note the future significance of old support/resistance levels (illustrated by the extra manually drawn dashed white lines).
The user can switch between these 2 modes, each offering a unique perspective on the market. This provides a more in-depth examination of the market, enhancing the user's trading analysis.
Using a copy of our indicator while using both modes can also be helpful.
🔶 DETAILS
The Support level is the opening price of a bullish volatile candle plus a user-set percentage of the candle's body, while the Resistance level is the opening price of a bearish volatile candle minus a percentage of the candle's body.
The following example illustrates the ATR with the multiplicative factor (Volatility Threshold) where the body of Volatile candles exceeds the ATR limits. Changing the Volatility Threshold and ATR length gives users extra flexibility to adjust to their needs.
🔹 Max Line Length
When using the Historical Mode and the duration of a displayed level reaches the user-set Max Line Length value, the level will return to the last test or be deleted when it has not been tested.
