Quote from tomu:
You should be able to easily find and office to trade in through Assent or Lightspeed. But Lightspeed's rates are .00395 per share and Assent's rates are similar if you trade out of an office. And you are less likely to negotiate a lower rate with them if you are trading at their office rather than from home.
You said you or someone else trades 100k shares a day which is 2 mil shares a month. With Lightspeed that is $7900 a month in commissions. As I previously posted in this thread the firm I moved my account to charges .00155 for 2 mil shares which is $3100 a month in commissions. That is a $4800 a month difference. Take some of that $4800 a month and rent your own office space for you and your friends.
clearing the trades thru where ? if you want to clear GSCO and use redi you'll pay more.....
