The max IB commission is 0.5% plus regulatory fees, usually that applies to stocks under $1 rather than the $0.005/share rate.Interactive Brokers is not for large volume traders or penny stock traders at .005 per share. They have to be out of their minds.
You can believe what you want, but I've got fills from today for about that size and the cost was $3-4 not $12.50. Honestly, $3-4 isn't a great price compared to some other places if you can get $2-3 flat rate trades, but it's not what you're quoting. Did you even read the "maximum commission" part right there on the website? The max per order applies whether you pick fixed or tiered commissions:Negative I just got off the phone with them. If you are trading margin it is 1/2 penny per share which is .005 multiplied by the number of shares. So 2500 share will cost you $12.5 to buy and $12.5 to sell which is $25. 25k will cost you $250 round trip, they have to be out of their minds. It hurts them because large volume traders will be reluctant to deposit additional money to increase leverage. They may be $5k cheaper than Speedtraders, but in the longer term it is well worth it. That right there kills them, I was ready to go into business and they're fees are not negotiable.
