We don't have bother with all the minor ECN's at this point. Remember, the most important thing for our traders is getting filled on 1000 shares or more. I'll post this again for reference. It IS essential to know where you're routing, can make a few $thousand difference each month. www.stocktrading.com/routing2012.xls Don
That info is a little bit outdated. If your trading strategy depends on some degree of the routing, check the exchanges sites every month for possible changes in the fee structure. They implement them mostly at the 1st and 15th day of the month.
I know the actual numbers vary, but since they are all pass through to traders anyway, not a big problem. Is there a major difference that I'm missing? Any destination not paying that was or anything? If so, please let me know and I'll check and change the spreadsheet. Thanks... Don
