## OR Node

The OR logic node applies a Boolean OR operation. Specific to BloodHound and fuzzy logic calculations, it identifies the maximum input value, and that maximum value becomes the output value. Simply put, the OR node combines all inputs together into a single output, and outputs the maximum of those values.

### Example

Imagine you had 3 criteria for a trading signal, and you want BloodHound to identify them. Your rules state that **if any **of the criteria is satisfied, you have a valid signal. After creating each criteria as separate solvers, you now have all 3 solver nodes added to the logic board.

To complete your logic, you would simply connect each of the 3 solvers to the inputs of the OR node. Lastly, you would connect the OR node's output to the *Result* node.

Connecting all 3 solvers to the OR node ensures that **if any** of the 3 criteria are true for a particular direction (or favorable) the OR node will produce a result. Conversely, the OR node will only produce a zero/nugatory value if and only if **all of the inputs** are nugatory. After connecting the *Result* node, BloodHound will plot on the chart all the bars where **any **of the 3 criteria were identified.

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.

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 .

# BloodHound v1

## OR Node

The OR node in BloodHound v1 and v2 function exactly the same. The only difference is how the node is visualized in the Property Inspector. See the BloodHound v2 section above for a description and example.
