Nothing to think about, 'hedging' intraday in the way they're doing it is only profitable for the broker because it costs the trader money. It's simple, in order to realize a profit the trader needs to be either net long or net short, there's no way of escaping that fact.
You're missing the reason why people like pqt have opposing positions on the same pair (or as they like to call it 'hedging'), it's not so they can trade different positional/intraday strategies. If you read some of their posts on other forums you will soon see that, like pqt, they trade that way on a session by session basis, pqt said himself "when I do use it, I always end the trading session in profits". They simultaneously trade long and short solely to be able to take profit irrespective of which way the market goes and that makes them feel good, but what they seem to fail to realize is that for every pip they make on one trade they are losing it on the other trade. Although their account balance is going up their NAV remains static or is actually going down due to spread costs. In order to make any money eventually they simply have to analysis the market, predict probable price direction, make a decision, and close/reduce one side of their 'hedge'. Their 'hedging' strategy is pointless, they may just as well have made an analysis and traded one way to start off with, realized a profit/loss, and saved themselves dozens of trades and spread costs in-between, not to mention saving time and energy. Broker love these people, they're paying for something without receiving any benefit or advantage from it.
The single spread and swap costs associated with positional trades lasting maybe weeks or months are negligible compared to the potential return unlike intraday where the spread cost could be >10% of the potential return on a trade-by-trade basis, but the point is they're not getting anything for their money, hedging in this way isn't helping them in the slightest.
The benefit of separating intraday and positional trading strategies in different accounts is that it's easier to manage and monitor longer term trades on one account, performance, return on investment, and risk are all clearer. Transferring funds between accounts is a very simple process taking only a few seconds, there is no need to have trading capital just "sitting there waiting for a trade, not working for me".
In any event this is all acadmeic, the NFA have quite rightly banned the practice.
