Increases or decreases an existing position by the specified factor as of the close.  

 

•Increasing a position size will result in the addition position units since the contract/share additions will have a different entry date than any of the existing units.

 

•Decreasing a position size will remove contracts/shares starting with the last unit on, and working back through the remaining units until enough quantity has been removed.

 

For instance:

broker.AdjustPositionOnClose( 1.4 )

would increase a position by 40%, while

 

broker.AdjustPositionOnClose( .8 )

would decrease the position by 20%.

 

This function is used by a Risk Manager Block to lighten a position to meet certain risk restrictions.  It can be used in other script where instruments have context.
