Jump to: navigation, search

Enters a long position as specified by the parameters. The entry point is visually indicated on a chart by an Arrow and a Tick. The Arrow identifies the time and the Tick identifies the price value of the entry point. Labels, displaying the entry name and the number of contracts or shares traded, are displayed below the Buy Arrow.

An order is executed at the point specified by the parameters; if the order is not filled within the specified bar, the order is cancelled.

When a Buy order is filled, any open short positions will also be closed.

Usage

Parameters inside the square brackets are optional - if these aren't defined, the default is used.

Parameters
