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.

Usage

Plot1 Cross Direction Plot2

or:

E1 Cross Direction E2

Where:

E - a numerical expression.

Direction - a required parameter which specifies the direction of the cross.

Above, Over, Below or Under parameters are used to specify the direction of the cross.

Notes

• 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:

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.

• 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:

The value of A was more 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 more than the value of B on the bar immediately preceding this sequence of bars.

Examples

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");

To open a long position if the close crosses above the 20-period moving average:

if Close cross above Average(Close, 20) then
