Comparison Solver
The Comparison solver analyses the relationship between input sources Indicator A and Indicator B. Both Long & Short outputs can be customized for multiple conditions.

This section provides quick access to commonly used output modifiers.
Please note: The buttons only modify the individual instance of the selected node(s) on a Logic Board. Thus, the buttons are only visible when a node is selected on the Logic Board. The buttons are not available when a solver is selected in the Solvers panel, because the original solver's output can not be globally modified.
This behavior is consistent with adding a function node afterwards, so that the original solver's output remains unmodified elsewhere in the system. It is similar to having an SMA(50) on several charts. Changing the plot color on one chart does not modify the plot color on the other charts.

Input A
This is the first input data to be evaluated against Input B. Use the Type drop-down menu to select the data type.
The menu will change based on which data type is selected. Click on Type to see the various data types available and the corresponding documentation.
This menu selects the data type to be evaluated. See below for detailed information on each data type.
Type: Fixed Value
Type: Price
This option allows price data to be used in the solver. The price data can be shaped/manipulated by the various settings before it is used by the solver.
Body Top: Regardless of the bar direction, this returns the higher price of the candlestick body. Either the close or open price. Whichever is on top. e.g. For an up bar, the Body Top equals the close price.
Body Median: This returns the median price of the candlestick body. The formula is (Close + Open) ÷ 2.
Body Bottom: Regardless of the bar direction, this returns the lower price of the candlestick body. Either the close or open price. Whichever is the bottom. e.g. For an up bar, the Body Bottom equals the open price.
Type: Volume
Volume will feed the current bar volume into the solver.
To evaluate the volume from a few bars back, use Indicator Value. Then select the VOL indicator, and use the Displacement setting.
Type: Indicator Value
Type: Swing Point Prices
Swing Point Prices uses the Swing Highs & Lows indicator plots for input price data. This is useful when you need to access the lowest low or highest high prices from the latest swing point.
You can add the bundled indicator Swing Highs & Lows to the chart to help you visualize the price data the solver is using.
Type: Linear Regression Channel
Input B
This is the second input data to be evaluated against Input A. For documentation scroll up to section Input A.
Use the Type drop-down menu to select the data type. The menu will change based on which data type is selected.
Output Rules
Options tab
Options tab
This section is used to modify the node's final output value. It is only useful for designing fuzzy logic systems, or a fuzzy logic section of a system.
Please note: The Weight controls only modify the individual instance of the selected node(s) on a Logic Board. Thus, the Weight controls are only visible when a node is selected on the Logic Board. The controls are not available when a solver is selected in the Solvers panel, because the original solver's output can not be globally modified.
This behavior is different than BloodHound 1.0. In BH 1.0, the Weight controls modified the nodes output globally (every instance). This change in BH 2.0 adds more system design granularity.
Multiply Output: This takes the internal values (the Long and Short values determined via the Properties tab » Output Rules section) and multiplies them by this value. Note: the final output will not exceed a value of 1, as described in the Slider control below.
Slider control: The slider constrains the final output to a value of 0 to 1. The left side of the slider sets a minimum value that is output regardless if the solver condition is true or not. The right side sets a maximum value that is output. The output is capped.
e.g. Three indicator conditions are being checked, and thus three solvers are created. Only two out of the three indicator conditions are needed. An Additive logic node is used to add the solver's outputs together. Just two out of the three solvers need to add up to a value of 1. Therefore, the right slider (max output value) for all three solvers is set to 0.5. When two indicator/solver conditions are found, thus the outputs = 0.5, then the calculation, in the Additive node, is 0.5 + 0.5 + 0 = 1. A value of 1 means the two out of three condition is true.
Hedge Operation: This applies a mathematical formula to the internal value.
None: No modification is applied.
Very (square output): A squaring formula is applied. Output = value^² .
Somewhat (square root output): A square root formula is applied. Output = √value .

Example: Show Long Signals Only When Price is Above an EMA (2 minutes)
Examples
Example 1A: The Basics
This demonstrates the basic function of Indicator Comparison solver with the use of a EMA 50 and the Closing price. This Solver will be used to determine if the Closing price is above or below the EMA 50.
- Add the Indicator Comparison solver
- Set Input A Type to Price
- Set Input B to EMA 50
The chart below shows a Long signal when the Closing price is above the EMA 50, and a Short signal when the Closing price is below the EMA 50.
Example 1B: The Basics & A Little More
This demonstrates the use of Large Amount & Small Amount properties of the Solver with the same set up as above. This example sets the Solver to allow price to break through the EMA Support/Resistance line by 2 ticks and still provide a signal in the same direction with other indicator. As price moves from 2 ticks to 5 ticks away the output is reduced.
- Add the Indicator Comparison solver
- Set Input A Type to Price, and Input B to EMA 50
- Set Large Amount to 5 Ticks
- Set Small Amount to 2 Ticks
- Set Long Output values as shown
- Set Short Output values a shown
The chart below shows a Long & Short signal when the Closing price is within 2 ticks of the EMA. This is because Long Output (A < B) By Small Amount is set to 1, and Short Output (A > B) By Small Amount is set to 1 which causes a signal to occur even if the Closing price breaks the EMA, allowing for a more organic system.
Example 1C: The Basics Using A Multi-Output Indicator
This demonstrates using the DM indicator with multiple plots. The Large Amount property is used to filter out unclear & choppy signals from the +DI & -DI plots. The Small Amount property is used to anticipate a reversal in signal direction by providing a 0.7 output value set in Long Output (A < B) By Small Amount and Short Output (A > B) By Small Amount.
- Add the Indicator Comparison solver
- Set Input A to DM » +DI plot
- Set Input B to DM » -DI plot
- Set Large Amount to 8 Points
- Set Small Amount to 2 Points
- Set Long Output values as shown
- Set Short Output values a shown
The chart below shows the choppy signals from the indicator were filtered out. Note A: When the +DI & -DI are within 2 points of each other an output in the opposite direction is given.
Example 1D: The Basics with Volume
This demonstrates using volume and a volume moving average with the Indicator Comparison solver. This example will generate a Long signal when volume spikes past the Large Amount, and generate a Short signal when volume drops below the Large Amount. The ATR is used in the Difference section to help normalize the volume’s volatility.
- Add the Indicator Comparison solver
- Set Input A Type to Volume
- Set Input B to VOLMA 14
- Set Large Amount to 100 ATRs
- Set Small Amount to 0 ATRs
- Set Long Output (A > B) By Small Amount to 0
- Set Short Output (A < B) By Small Amount to 0
The chart speaks for its self.
Example 2: Finding Higher Lows & Lower Highs
This demonstrates using the built in Swing indicator of different Swing Sensitivity with the Indicator Comparison solver. Indicator A is configured for minor swings. Indicator B is configured for major swings. The Solver will look for higher low points of 15 ticks or greater for a Long signal, and lower high points of more than 15 ticks for a Short signal.
- Add the Indicator Comparison solver
- Set Input A Type to Swings
- Set Input A values as show
- Set Input B Type to Swings
- Set Input B values as show
- Set Large Amount to 15 Ticks
- Set Small Amount to 10 Ticks
- Set Long Output (A > B) By Small Amount to 0.5
- Set Short Output (A < B) By Small Amount to 0.5
Notice on the chart, the lower high was 13 ticks instead of 15 ticks as set in Large Amount and a signal was given. This is because the Short Threshold is set to 0.8 (80%), the Small Amount is set to 10 ticks, and Short Output (A < B) By Small Amount is set to 0.5. At 10 ticks the output = 0.5. Small Amount to Large Amount is 5 ticks, so every tick = 0.1 in the output. Therefore 10 ticks = 0.5, next 3 ticks = 0.3. Result is 0.5 + 0.3 = 0.8
