If-Then Node
The IF THEN node acts like a switch. The switch is controlled by the IF connector. When a signal comes in, what ever is connected to the THEN connector passes through to the Output. When there is no signal, what ever is connected to the ELSE connector passes through to the Output. Either the THEN or ELSE always passes through to the Output. The Long output and Short output each have their own switch inside the IF THEN and are evaluated separately.
Illistrated Examples
When a Long signal comes in to the IF , the Long data from the THEN passes through to the OUTPUT. But, the Short data from the ELSE passes through to the OUTPUT, because there is no Short signal to the IF.
When a Short signal comes in to the IF , the Short data from the THEN passes through to the OUTPUT. But, the Long data from the ELSE passes through to the OUTPUT, because there is no Long signal to the IF.
When a Long & Short signal comes in to the IF , the Long & Short data from the THEN passes through to the OUTPUT. Nothing from the ELSE passes through to the OUTPUT.

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 .

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 video demonstrate how to set up the logic to use the If Then node so that system A (connected to the IF and THEN inputs) can override system B (connected to the ELSE input). e.g. When system A has a long or short output, it will always show system A on the chart. But, when system A is neutral (zero outputs), that is when system B will show on the chart. In this example system A identifies an overbought/oversold condition, and system B identifies a trending condition.
