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.
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.
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
or
b) 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.
The plot of A is defined as having crossed Below or Under the plot of B if the value of A is less than the value of B and one of the following is true:
a) The value of A was more than the value of B on the bar immediately preceding the current bar,
or
b) 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 more than the value of B on the bar immediately preceding this sequence of bars.
Usage
E1 Cross Direction E2
or:
Plot1 Cross Direction Plot2
Where: E - a numerical expression
Direction - a required parameter; specifies the direction of the cross
Example
Trigger an alert on the bar where the Close price crosses above 1350.00:
Plot1(Close);
If Plot1 Cross Above 1350.50 Then
Alert("Price has crossed above 1350.00");
