how does a person make money by hedging when they go long and short on the same currency pair, what is the rational behind this.

Also what's a good honest broker that provides leverage up to 400

Hi,

Generally, most retail traders use hedging when they are in a losing trade position.

For example, I might go long the EUR/USD, but the market price immediately tumbles down. In order to protect myself against further losses, I place a short order so that any further downard movement in price will not affect me — I may lose in the long position, but I partially make up for that loss by the gains in my short position.

This is how most traders I know 'hedge' against losses. Unfortunately, this is a terrible way to trade.

I have done a lot of research on the best managed forex accounts…

I suggest you sell your research as an eBook on ebay amd perhaps consider charging people to attend 'training classes' in Forex gambling (typically there is a lot more money to be made in selling 'How To' books and holding seminars etc. than in actually doing any real trading)
