Ronald Raygun has responded to this question but it's still not making sense to me . Why would an account trading $4000 @.02 lots use more margin than an account trading $2000 @.01 lots? Shouldn't they use the same? This forces you to keep opening more accounts to spread your money out so you can keep your lot size small. The problem with that is that brokers limit the number of accounts you can have. Thanks for any insight.
