Sometimes, it is so upsetting to notice that a buyer did not bother to read the system's documents. I told TSTW 24 traders to stay away from useless financial instruments that have no momentum, no one is trading them and they are not going anywhere.
A day trader needs to trade financial instruments that have momentum and nice trading volume. Stay away from illiquid financial instruments. Also stay away from financial instruments that make you lose more often. Just bin them and only focus on those that are responding positively.
So why am I saying that?
Well, it is because during the back testing of a system, one discovers new elements or factors. Now, you can imagine that the system builder will not be very pleased if people do not take on board those warnings after putting in many hours to test and retest the system.
Without getting too emotional on this matter, one must test a system that one has built. One will test it on various financial instruments at different times.
The purpose of that test is to optimise the system. Like I said before, a valid trading system can be used for all financial instruments on every time frame, but for the sake of the best optimisation, one will only draw rules that boost the system. Am making sense or talking too much?
Please note that after the initial testing, the testing still continues every time the system's builder is using it. With that, one can help users get the best out of the system.
I can continue sharing more tips about what can help one build a valid trading system, but I will stop for now.
The best way to show someone how to build a system is to build it from top to bottom in front of him or her. Really, what we can do is to record a live video, and start the process from A to Z; so technical traders can see me build a valid trading system that works.
