If you're risking say, .5% or 1% of your account on each trade and your account is $100,000 would you have your whole account in play or only a proportion of it? That is, would you have 100-200 trades going on simultaneously(which I'm guessing one wouldn't because of the admin. load). If not, then what would people recommend as an optimum proportion to be out working on your behalf? Does it depend on the circumstances pertaining at the time?
