...So it turns out it is the assumption that "if too many people know about it, it won't work anymore" that prevent traders from sharing...
Hi ion,
It's more like
if too many people know about it, their improved performance will make my performance not seem so unique.
This applies to liquid markets only.
Therefore, if I had some edge in trading something illiquid...probably not a smart thing to share how your exploiting that illiquid market.
Regardless, it always comes down to what the actual edge is that's being shared.
Simply, there are some edges when shared...their performance level will not be affected no matter how many people are aware of its specific details.
Yet, there are other edges when shared...there will be a negative impact on their performance.
Also, not discussed a lot, although many threads at ET are proof that when a method is shared...
It's applied differently, parameters changed (altered), applied on different trading instruments by those with a strong interest in it after receiving the details of the method.
These threads displays the repetitive aspect of the human psychology in the markets where we need to change something to make it feel like our own.
Thus, when I meet someone that saids they have a profitable method but don't want to share it...
I believe this is a trader that knows his/her methodology well enough to know that sharing it will have a negative impact on his/her own performance level.
Just the same, when I meet someone that saids they have a profitable method and wants to share it...
I believe this is a trader that knows his/her methodology well enough to know that sharing it will not affect his/her performance level.
Some traders fear the competition while other traders do not fear the competition.
Last of all, I want to put a lot of emphasis on something I mention before by mentioning it again.
More often than not those that you see that are not sharing are actually sharing...
They just aren't sharing with you.
