globex futures? never heard of what is it... where is it... and is it as volatile as forex? can I play in both directions? is it as flexible... as spot trading?
I am just saying, I wouldn't discriminate against a broker for offering 20/1, 10/1. As for using less money and open same size position with leverage. I have heard that some brokers will charge you higher interest for the extra leverage. I don't know if this is fact though. I know equities brokers do this, that is why I typically will trade with a cash account instead of a margin account.
