Used in combination with Cross to specify the direction of the cross. Below specifies a downward (greater to a lesser value) direction.

Usage

Plot1 Cross Below Plot2

or

E1 Cross Below E2

Where:

E - a numerical expression.

Notes

The plot of A is defined as having crossed Below 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.

For more information see Cross.

Examples

Trigger an alert on the bar where the Close price crosses below 1350.00:

Plot1(Close); 

If Plot1 Cross Below 1350.50 Then
    Alert("Price has crossed below 1350.00");

To open a short position if a 5-period moving average crosses below a 10-period moving average:

If (Average(Close, 5) cross below Average(Close, 10)) then
	SellShort ("ES") 1 contracts next bar at Market;
