[[Above, Over, Below,]] or [[Under]] parameters specify the direction of the cross; [[Above]] and [[Over]] are transposable and specify an upward (lesser to a greater value) direction, and [[Below]] and [[Under]] are transposable and specify a downward (greater to a lesser value) direction. == Usage ==<syntaxhighlight>Plot1 Cross Direction Plot2</syntaxhighlight>
The plot of A is defined as having crossed [[Above]] or [[Over]] the plot of B if the value of A is greater than the value of B and one of the following is true:
a) The value of A was less than the value of B on the bar immediately preceding the current bar <syntaxhighlight>E1 Cross Direction E2</syntaxhighlight>

The plot of A is defined as having crossed [[Below]] or [[Under]] the plot of B if the value of A is less than :'''Direction''' - a required parameter; specifies the value of B and one direction of the following is true: cross.

Returns a value of [[True]] if, on the current bar, the plot of a numerical expression A crossed the plot of a numerical expression B in the specified direction.
== Notes ==* [[Above]], [[Over]], [[Below]] or [[Under]] parameters specify the direction of the cross.* [[Above]] and [[Over]] are transposable and specify an upward (lesser to a greater value) direction, and [[Below]] and [[Under]] are transposable and specify a downward (greater to alesser value) direction. * The plot of A is defined as having crossed [[Above]] or [[Over]] the plot of B if the value of A was more is greater than the value of B on and one of the bar immediately preceding the current bar, following is true:
::The value of A was less than the value of B on the bar immediately preceding the current bar, ::'''or'''::The values of A and B were equal for a consecutive sequence of one or more bars immediately preceding the current bar and the value of A was less than the value of B on the bar immediately preceding this sequence of bars.
==== Example ==Examples ==
Trigger an alert on the bar where the Close price crosses above 1350.00:
<syntaxhighlight>Plot1(Close);
If Plot1 Cross Above 1350.50 Then
Alert("Price has crossed above 1350.00");</syntaxhighlight>
To open a long position if the close crosses above the 20-period moving average:
<syntaxhighlight>
if Close cross above Average(Close, 20) then
Buy 2 contracts next bar at market;
</syntaxhighlight>
