when you mentioned broker, you mean the firm or the employees it hires? i guess your mean the firm, which is not the topic we are discussing here.
Wouldn't matter what I was talking about for two reason:
1. Employees and brokers have a fiduciary duty to their clients
2. A single instance of proving a breach of this contract could destroy a broker
3. Commissions are high enough that everyone is making enough money no one would care
4. Even if they did care a few employees stealing your strategy, assuming they have the capital, tolerance, and total information to do it, won't compromise your edge.
In the context of you being a consistently profitable trader.
Do you think it is more profitable for the broker to:
1. Just Charge commissions
2. Free commissions but follow your trades
3. Charge commissions and follow your trades
(1).
Zero risk in charging commissions. If they want to punish you for "being too good" they'll raise commissions. If your strategy is so good you're making 10,000 trades a year at $2/side they're already crushing it. Now scale that up to 100,000 clients and they don't really care about you.
To both of you - who cares if someone follows your trades anyway. More importantly - why would a broker risk executing a trade they do not fully understand? The entire premise of this argument is contingent on perfect information which they don't have.
Don't believe me? Believe there's a giant conspiracy? Let's play a game of numbers:
1. A broker employs 10,000 people.
2. Lets say around 1,000 of these people are responsible for their "trade stealing" department. Seems reasonable if they're doing this for the ~25% of their clients that make money.
It's been theorized that
no more than 125 people can keep a secret. This would leak in one way or another and destroy the trust in the system. Since it hasn't leaked, the most reasonable conclusion is this conspiracy isn't real.
