Why would you only be trading with half your funds? You make trades in both accounts on any day. If you have an outage you use the remaining account to do the hedging for the account that is down. It works fine with equities. Some firms offer free news, other firms offer interest on your idle balances. You can use different features from each system to achieve your objectives.So I'd be trading with only half my funds for that 0.1% chance of a outage? It could work with futures but not with equities.
