Is Crossing Value [Cross]

Return to Complete List of Functions

The Is Crossing Value function indicates when a data series crosses above or below a given threshold. Parameters ------------------ Data          The value to compare. This is typically a field in a data series or a calculated value. Threshold  The threshold to compare the data to. This can be a constant, a field, or a calculated value. Function Value ------------------------ The function returns +1 only when the field actually crosses the threshold. In all other situations, it returns 0. For example, in the table below, notice how the value is +1 when the closing price actually crosses above or below the value 3. Close     Cross(Close,3) -------------------------------------    2                  0    3                  0    4                  1          <--- Close crosses above 3    5                  0    3                  0    2                  1          <--- Close crosses below 3    1                  0 Usage ----------- The threshold can be a constant or another data series. For example, this function can be used to determine when a data series crosses its moving average. Crossing functions are typically used in entry/exit systems to generate signals when one value rises above another value. See the sample entry/exit systems for an example of using crossing functions in an entry/exit system.
