As any house won't stay without good foundation as any trading system won't work without data and
software. It is the very beginning of this kind of system, so-called setup. Data consist of two parameters: price history and live prices. This step is done on purpose, the first criteria will be used for back
testing. It is rather essential procedure on initial periods of developing trading strategy. The task will be comparison current situation with the one that was several weeks/months ago.
The next step is a proper design: as the information that is interesting for a person will appear in windows and tabs. The convenient structure of saving and organizing all lines in an appropriate way makes
trading systems more useful for the consumers.
Specifying what one wants to get to know from a particular system is also a part of designing. One should determine which kind of market is his/her target, which time periods, price series, subset of equities should be used in one's particular case.
Practice and testing are the things that are done by default. All possible errors should be revealed for better trading system operation. When it is in use, there is not time to calm down and relax. It is only the beginning. Repetition of all processes is necessary, because it is impossible to foresee everything that may happen on the market. Gold mean should be also found in
trading system optimization as any system is recommended to be as broad and flexible as possible.
