There is no benefit to this strategy and our system does not allow this. Simply put if you are placing two $25 trades on two different brokers you are simply placing $50 trade on a single asset so it is better just use one broker to do that.
What we do offer is to be able to connect with multiple broker accounts but trading can only be done with one broker at a time because of the reason explained above. The benefit of having multiple broker accounts is to be able to separate your risk of having all your money in one broker account. Also when it comes to withdrawals it is better to request to withdraw smaller amounts with more brokers rather than requesting to withdraw large amount from one broker.
