Just out of curiosity, I am posting a poll to see what others are paying to trade e-mini's. I just switched brokers and reduced my costs from $5.75 per RT to the $4.15-$4.25 range per RT, based on the monthly volume I trade. The reason its not a single figure is because I now pay a $550 monthly platform fee, whereas previously it was incorporated into the pricing. Times have changed, 6 months ago IB seemed the undisputed pricing leader at $4.90 per RT, while some place still wanted to charge me over $10 per RT (I declined their offer). So my poll question is simple. Approximately how much do you pay per round trip on average, including any monthly platform costs that have to be averaged into your trading costs.
