Are you thinking about making the Webtrader or iPhone App available for your contest?
In my opinion most people (that have a job) can't use JForex during the day and therefore it's impossible for them to enter or cancel trades. Normally I don't trade before 9 am and therefore I can't enter my trades correctly because I have to go to work earlier
And if I enter trades in the morning and things change during the day I can't do anything about it and I just have to wait until I get executed
At the moment it's more like a gambling contest because people use to much leverage (no serious trader would EVER risk more than 5% of his account). I have to say that I use huge positions as well because you don't have a chance to win without using monster positions
I know it's probably been written from other contestants as well but I just wanted to say it again.
