Signal Counter Node
The Signal Counter node outputs a signal when the specified number of bars with signals is counted within the Lookback Period. The counting can be reset to zero using the Reset conditions. The Signal Counter is used to count the number of bars with whatever various condition is needed. A few examples are provided below.
e.g. It may necessary to know if the Stochastics was overbought/oversold for at least 5 bars in order for a condition to be met. Or, on a renko chart, a minimum of 3 pullback bars are required in order for a pullback in price to be recognized.
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.
The Reset option is used to turn off or reset the node's functionality, and is common to several Function nodes. Function nodes that can be reset have a unique Reset connector to receive a specific signal designed to identify when it is time to stop/reset the node.
e.g. If the Signal Blocker is actively blocking signals and charting conditions have changed making it Ok for the next trade signal to occur, then the Signal Blocker should be reset via a signal to the Reset connector. Otherwise, trade signals will continue to be blocked until the 'Block Signals For' period ends.
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 v126.96.36.199 or newer is required for the built in web viewer to work, and thus the documentation to be displayed.
This simple example comes from the weekly workshop on May 4, 2023.
Signal Counter Node
The Signal Counter node gives an output signal when the specified number of input signals is reached, during the Lookback Period. The counting can be reset to zero using the Reset conditions.
