So, I am asking you again then. You want to randomly switch brokers between your entries and exists? Because that is what you gotta do unless you do not care that a simple pattern can be established even by a third grader which in turn would negate your whole idea. And I ask you also this again: What do you have to fear from a regulated broker to whom you submit exchange traded orders? Makes zero, absolutely zero sense to freak over this, certainly not warrant switching back and forth brokers. OP clearly gives away the impression he is a retail type of guy. Your idea would require intelligent money management, the observance of margin levels and account balances because you are essentially 100% directionally exposed in both accounts. Also, let me ask you: What do you do if you went long with broker A in account A and now want to exit the position? You need to short (not sell) your position in account B. I think it is clearly you who did not think of many issues that your idea entails, issues that lead to much more complexity than you ever thought of. Good luck with your idea...
There is nothing complicated (excuse of you)about spreading entry and exit orders over 2 different brokers, you simply can't admit that the solution is simple as that , that you had not thought about it ,....grow some brain....small ego
my goodness!
