i've been a long-time fidelity customer and have a ton of products with them and have done all sorts of weird and wacky stuff with them. historically i've stuck with trading mainstream stocks so i've been happy with fidelity, even though it's a bit more expensive than other options. however i've recently gotten into trading higher volumes in low-priced stocks (not pinks and bbs). fidelity, schwab, td, and most brokers do not support this type of behavior via per-share commissions --- 35K shares at fidelity costs $750 or so to get in and out - it's not reasonable. obviously i'm not (yet) a sophisticated consumer of these services, but i'm working on it . i'm looking at ameritrade and scottrade - both support flat fees. ameritrade seems to provide a lot more "stuff" than scottrade. fwiw, $7 -vs- $11 is a wholly inconsequential delta. any advice or pointers much appreciated. tia, doody.
