Quote from cloudy:
I thought I heard most of the older trading systems (20 to 40 years old) don't work anymore because it's harder to track inefficiencies and there are tens or hundreds of millions of new retail traders worldwide. Plus HFT , algos, and stop running is ruining many systems, trend following or otherwise. Certain stocks keep getting hammered back down by the shorts. In general it's just plain harder to trade than before. The "golden age" of daytrading may be in the past decade or more. Even with a good system, one may have to wait days or even weeks for conditions in the market to be tradeable again for a particular market. It would make sense that any system that worked are closely guarded secrets , if revealed would lose their edge fairly quickly by hundreds of thousands who latched on to it as well as HFT adding another system to their array of systems to stop hunt and ruin entries.
Here is a corollary of what I mean. Here we have a guy (that probably doesn't trade for a living) that is echoing the same thing (save the algos..although before algos traders manually performed the same fuctions that computers do now) that others have said over the past few decades. He also seems quite indoctrinated into the buy only side or buy and hold mentality ("stocks are always hammered down by the shorts."). Did it ever occur to him that he can set up a method to profit on the short side as well? Guess not.
I am 43 now so I can say that with some degree of experience. There used to be floor guys running stops..etc etc. Same stuff different day.
What he is saying is basically...profitable systems are like the holy grail, any one of them that works must be a secret, and the edges diminish quickly.
The most important aspect of failure in trading is failure to follow a system. It isn't finding the "best" system, because there isn't one "best" system. Each trader has his own tolerance for risk volatility heat etc, and different methods or rather different traders fit different methods.
If I were a beginning trader, day trader, whatever I would do this. First, find or create a system. Second, match the risk management to the level of your risk capital. Third, make every effort to follow the system exactly win lose or draw. If you do those three things, either you will succeed financially or you will lose, but in losing you should be able to have the confidence that you followed your method, and that should lead to a modification of the method if it didn't work well enough or some other key that will support you in becoming a good trader. The key ability though is not the best method, but the work you will inevitably need to do in order to follow a method. Sound easy? if it does that's why you are failing. This is where most of the work in trading is, and where the rewards follow from. If you survive these trails you will eventually find and hone the system you can follow, and have the necessary psychological skills to trade your plan effectively.
Too many traders make the deadly mistake of thinking trading is about finding or creating the best system. It isn't about that, it is about having a reasonable system and executing it like a master.
