Just like Budweiser, traders have born on dates and you better know yours.
I could spend chapters and chapters writing about the differences between traders. Even if you gave 2 traders the exact same courses at the exact same time and asked them to read the same books and exposed them to the same financial media, you still get two different traders with two distinct trading styles.
Trading is an individual thing. Even when exposed to the exact same inputs over time, each trader will assimilate only that information that they relate to. Each trader is exposed to and tries to understand a huge amount of information. But only so much information gets in. The remainder of the information is simply discarded or stored in some deep recess of the brain until some new input generates some recognition of relevance and that information may be revisited.
So what you end up with is an almost purely random path from the start of your trading experience to where you are now. Even when the input is controlled you never be the same as the trader sitting next to you.
That doesn mean a group of traders can be exposed to the same trading system, and taught how best to execute it aka the turtles and their commodity trending system but for the most part, no two traders will be alike.
There are so many variables that cause differences between two traders a big one is what I like to call the born on date. Born on date is just as it used with the beer companies, it what the market conditions were when you first got exposed or involved in trading. So if you started your trading experience in a bear market, you a bear and is you started your trading experience in a bull market, then you a bull. You never loose this underlying bias. It engrained in your brain.
Ok, sounds like a simple concept, but the brain is such a complex organ that we know so little about that the paths it takes to make a decision and those paths will just never be mapped out.
How do we use this to your advantage? First and foremost, consider your born on date. Did you take up trading in the stagnant 80 the rip roaring 90 or the bearish early 2000 Your born on date will determine your underlying bias to your trading. You ever notice that you trade better in bear markets or bull markets?
Second, when you communicating with other traders, note their born on date. Not like you can turn them over and read it on the bottom of their shoes. So you have to do a little digging.
Why is this helpful? Well, we always getting input from various sources. Now, knowing the born on date from the source of the information allows you to remove their bias and get a clearer read on the market or information being presented.
