The AND logic node applies a Boolean AND operation. Specific to BloodHound, it identifies the minimum input value, and that minimum value becomes the output value.
Imagine you have 5 criteria for a trading signal, and you want BloodHound to identify them. Your rules state that all 5 criteria must be true (or favorable if using fuzzy logic) in a given direction (long or short) before creating a trade signal in that direction. After creating each criteria, as separate solvers, you now have all 5 solver nodes added to the logic board.
To complete your logic, you would simply connect each of the 5 solvers to the inputs of the AND node. Lastly, you would connect the AND node’s output to the Result node.
Connecting all 5 solvers to the AND node ensures that all 5 conditions are occurring at the same time for a particular direction before the AND node produced a signal. BloodHound will plot on the chart all the bars where all 5 criteria are true.
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.
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 .
This text area provides a place to write a full description of what the node is doing, used for, or what ever you want.
Note: The Description is global to all instances of the node. It is not applied individually to each instance as the Weight controls are.
This tab displays the documentation page (from this web site) of the selected node.
Please note: NinjaTrader v18.104.22.168 or newer is required for the built in web viewer to work, and thus the documentation to be displayed.
The AND Logic node behaves like a fuzzy logic AND. The resulting output will be the minimum value of the inputs (a fuzzy AND operation).
Imagine you had 5 criteria for a trading signal you are looking to represent in BloodHound, and your rules state that all 5 statements must be true (or favorable) in a given direction (long or short) before creating a trade signal in that direction. After adding each criteria as separate solvers you now have all 5 solver nodes added to your logic template workspace.
To complete your logic, you would simply connect each of the 5 solver’s outputs to the inputs in the AND Logic Node. Finally you would connect the AND logic node’s output to the Result node.
Connecting all 5 solvers to the AND Logic Node would ensure that all 5 had to be true for a particular direction (or favorable) before the AND logic node produced a favorable result. BloodHound would now indicate on your chart all the areas where all 5 criteria were satisfied.
