OptionVue
5 Support - OpScan Basics
OpScan works
by "formulas" which query our data base to find trading
opportunities. There are 13 built-in formulas developed by OptionVue
Systems which can help you find excellent trade opportunities,
or modify them to suit your needs. You can also create custom
formulas from scratch to quickly find trades based on your personal
criteria. These
formulas tell the OpScan service exactly what to look for. No
more scanning option chains or newspapers. Opscan automatically
searches for you!
You use
the simple OpScan "language" to create a formula.
These formulas will contain expressions like:
LAST >
1.5 AND VOL > 500
Now don't
panic here! These formulas are easy to understand and use, even if
you aren't an algebra buff. Let's take a quick look at the basic
structure of an OpScan formula.
Elements
of an OpScan Formula
OpScan formulas
are strings of precisely defined Parameters and Operators. Each
parameter helps you filter the market to find exactly what you
are looking for. You can create OpScan formulas from scratch,
or copy and modify existing formulas, your choice. OpScan is
extremely flexible and helps you filter out unwanted data quickly
and effectively.
To help
you better understand how OpScan formulas work, let's break
down the composition of the "Exceptional Put/Call Volume
Ratio" formula, explaining what each field does step-by-step.

The "Title
field" is simply the name you want to give the formula.
The "Pick
field" is the heart of the scan as it describes what assets
or options you are looking for. Only items that qualify are
included in the report - the rest are filtered out leaving you
with the best candidates!
This scan
looks for assets that meet the following criteria:
PVOL$ /
CVOL$ > 2.5 means: The Put Dollar Volume divided by the Call
Dollar Volume in this asset is greater than 2.5 today. The put/call
ratio is a widely used indicator of investor sentiment. The
large amount of dollar volume in puts relative to calls is a
bearish signal for this asset.
ATVOL(5)
> 200 means: The Average Total Volume over the past five
trading days is at least 200 contracts. This statement ensures
that the qualified candidates we receive have a fairly liquid
market in their options. The operator AND means that only assets
that satisfy both statements will be listed on the resulting
report.
The Sort
field contains a (typically simple) formula that specifies how
you want to sort the report results (the order qualified items
are listed).
PVOL$ /
CVOL$ means: Assets with the largest amount of Put Dollar Volume
relative to Call Dollar Volume will be at the top of the results.
No manual sorting required!
The Show
field tells OpScan what information you want on the report.
All reports automatically include the asset name, symbol, and
sort value. In this report, the Put Dollar Volume and Call Dollar
Volume for each of the qualified assets will also be displayed
in the final report.
The "Include"
section allows you to select only those types of assets that
you would like to consider.
The Max
Number of Items field lets you enter the maximum number of qualified
candidates that will be listed on the report.
When creating
your own or modifying existing formulas, the Test Syntax button
gives you an easy way to see if your formula will work. A syntactically
correct formula might not find any qualified items. This doesn't
mean anything is "wrong" with your formula, just that
no items matched your criteria.
Running
An OpScan
You can
run as many formulas at a time as you want, or run them periodically
throughout the day to find new opportunities. To start, simply
check the box next to the formula(s) you want to run and click
the Connect button.

OptionVue
5 automatically accesses the OpScan server and submits your
request. A confirmation dialog box shows the formula was accepted
and the progress of your scan. Don't blink! OpScan is remarkably
fast. A typical scan takes only a few seconds.
When it
is finished, the OpScan server sends its official report(s)
to your computer. OptionVue 5 then collects the report(s) and
places them in a designated folder where they can be viewed
or printed at your discretion.
