What is Visual Pattern Designer
Let me tell you a story. I am a computer programmer and a few years ago I was working for a company that was involved in trading with securities. One day we got this wonderful charting software package, that not only had real time charts, but it also allowed the users to design their own market indicators and trading systems. It contained a simple programming language in which you could write your own miracles. I was so excited about it that after a week I knew my way around most of its commands. I bragged to my boss about the abilities of the new charting package a lot.
- Give me five minutes and I'll have your favorite trading system programmed and tested, I was claiming.
- O.K., he said, write this one: buy when a "head and shoulders" pattern is encountered. Sell on the mirror image of that pattern. Let's see what that system does.
- You’ve got to be more specific, I said. You can buy when the high is greater than the previous high, or something like that, but "head and shoulders" is a very vague term.
He took a piece of paper, and drew a few bars on it.
- That's head and shoulders. Let's see how it performs, he said.
- Wait a minute. What if I move this bar up a little bit. Is that a "head and shoulders" too?, I said, while modifying his drawing a little bit.
- Aha.
- And this, too?, I put another scribble on the paper.
- Sure, he said.
After an hour I was frustrated, and he still did not have his "head and shoulders" programmed. We killed the whole day together for me to understand what exactly (if there was such a thing) he meant by "head and shoulders". A week later, he was still not happy with my implementation of "head and shoulders". The next week I was working on a pattern called "diamond". It was even worse. By the time I got versed in fulfilling his requests, the software package started complaining that I had exceeded the maximal allowed program length (about 2 pages, by the way). By that time my boss was having serious doubts about my programming abilities.
I am daydreaming while writing this story. If a man from the future had come to town when I was writing that "head and shoulders" program, and asked me if I wanted him to bring me something from 1994, I should have said, “Bring me a copy of Visual Pattern Designer”. It would have saved my job. Good pay, too.
When I claimed "Give me a few minutes and you will have your system", if I had had Visual Pattern Designer, I would not have been lying to my boss. It allows me to pick a pattern from any chart, modify it a little bit, and search for approximate matches throughout years of data. It conveniently displays the outcome from the matching patterns, so I can see if my pattern is any good right away. Once I like the pattern, I can save it and use it in the future. I can incorporate the pattern I designed into my trading systems (programs) without having to spend that week programming.

What does the “Professional” add to it?
Since our release of the first version of Visual Pattern Designer, we followed a lot of suggestions from our users. Some wanted to see the patterns in a chart. Some needed a simpler way to edit a pattern, and some suggested other simplifications of the user interface. Everything we found reasonable we put in the professional edition, but that is still not a reason to call it “professional” and charge more money for it. Here is a question that we could not answer with the first version of Visual Pattern Designer:
- “Can I have a pattern that defines a relationship between the High and its moving average?”
- “Yes and no” - we said. “The moving average is only a derivation of the price itself. Just find the desired situation in a chart. That is your pattern.”
- “What If I can’t find it.”
- “It may be an inconsistent situation if you can’t find it.” - we &^%%$#!@-ed our way out of it.
That went O.K., but check this one out:
- Can I define a pattern that relates two different markets?
We had to answer this question in a Professional manner: “Visual Pattern Designer Professional will be able to do that.” - We would say.
Visual Pattern Designer came with a few Easy Language scripts that the users could run in order to make it communicate to TradeStation or SuperCharts. For the Professional version these scripts had to be rewritten every time the user changed the choice of indicators. The user would not want to do this. So who else but Visual Pattern Designer Professional had to learn how to do write programs in Easy Language. I admit, we got carried away with this idea, but now you can develop complex trading systems without writing a single line of Easy Language code. You will barely touch the keyboard when using Visual Pattern Designer Professional. All you have to do is pick choices and draw market situations with your mouse. Will these systems be inferior to the ones programmed by typing? No, quite the opposite, Visual Pattern Designer uses matching methods that cannot be programmed in thousands of lines in Easy Language. A lot more than the maximum allowed. We can do it because Visual Pattern Designer Professional calls external programs written in C++. They run a lot faster, too.
