you must be better than warren buffet or george soros? lol
let me give you an example.
in real life, warren buffet has this "ABC strategy" to trade market, and he also has this mutual fund companies and allow public to invest and let the fund manager do their trades.
so technically speaking, based on your logic warren buffet must be also destroying of failing his "ABC strategy" because hes not only trade his own money, but add up the investor's money (same logic like your 10k trader use your ea)? are they failing or this is just your 'theory'?
There is a difference between trading and investing .In trading Eas demand from the masses would dry up liquidity at particular signal triggers.If the profitable E A was posted on a website,the masses would learn about it and start trading it , often triggering demand 100k lots within a few seconds of each other. Trading is about precise timing ,whereas Stocks are invested in at different times and spread out over available liquidity,therefore they are not failing.
If the EAS in this thread were profitable, they would cease to remain profitable because 100 k lots bids/offers simultaneously would kill the edge.
furthermore, i know there are company participate in world series trading competition, got high ranking in the result list and had quite amount of respect in trading arena. that company also offers managed account from public, so again, based on your logic is this company suppose only trade their own money, or starts failing their strategy in future?
even.. assume all those strategy will only used by their own, neither it will be disclosed whatsoever, when their capital doubles or gaining profit. they most likely will continue to trade with the profit money, right? so is there any different if letting people invest (same as amount of money from profit)? is this failing the strategy sooner? think again, im not saying anything fiction, this is the calculation.
None has successfully ever made money for investors.
you only might need to worry if your ea is that good, JP Morgan, UBS bank can offer you billions to own it.
These are closed shops,therefore they are difficult to sell to , unless you are already on their lap.Once the logic is out, they will employ their own wiz kidds to clone it.Most hedge funds, if we are expecting to set up one for an investment bank,were started by investment banks,by setting up existing bank employees as fund managers.A google search will prove that.
