Before you create slaves, you need to decide how many slave strategies you
want. By default, you get two slave strategies. You can specify up to twelve.
To specify a number of slave strategies greater than two, display the Slave
Strategies menu and open the Slave Count field. Then, enter the number of slave
strategies you want. Specifying a number other than two expands the slave
strategy table, creating the number of records you enter. For example, if you enter
the number six, the slave strategy menu creates six records, one for each slave
strategy:
For all pricing model variables, the following gradation types are available:
% Change from the current value (default; gradation created by dividing 100%
by the number of slaves selected)
Difference from the current value (difference in days for time).
Once you make a gradation type selection, the Slave Strategies menu
automatically produces default gradation levels. However, you are not bound by the
default gradations. If you want to change a gradation for any slave, position the
mouse pointer on top of the gradation you want to change and click the left
mouse key. This displays the gradation value in an edit box. To change the value,
type an alternate value and press
For example, to create slave strategies that show time decay on a percent
change basis and volatility increase as expiration approaches on an absolute
difference basis, you would set the table up as follows:
This table creates strategy OEX1 that has a time to expiration that is 16.67
percent less than the actual time to expiration. Furthermore, OEX1
Creating slave strategies has two effects. First, it renders more lines on
your options chart. Second, it creates slave strategy menus for each slave
strategy. Let
As a result of creating six slave strategies, you option chart would display
six strategies:
The master strategy is colored green. Slave strategies are colored using
unique colors. Use the cursor window and the option chart labels at the top of the
window to identify the color of each strategy.
Additionally, the content of the Strategy menu changes as follows:
Creating Slaves
| Each slave strategy is assigned a unique name. The unique name employs the
name of the master strategy followed by a unique number (1, 2, 3, 4, and so on).
If you create slave strategies from a strategy named oex, the resulting slaves will be named oex1, oex2, etc.
Choosing a slave strategy displays a Strategy menu for the slave strategy. For example, selecting a slave strategy named bonds1 displays the following menu: This menu is created when the slave strategy is created and will remain until you delete the slave strategy. The functions on this menu are specific to the slave strategy: |
