Scottrade is $7 per trade regardless of size (sometimes it's a few cents more). Is there anywhere cheaper? I've seen some places that are between $0.99 and $5 per trade but they have inactivity fees. Sometimes I go a few months without trading. I'm very happy with Scottrade's service but if I can save a few bucks per trade I'd be very happy with that, too. I found Options House which has $3.95 commission per stock trade but I've read some things on this forum that make me a bit hesitant (like stop orders always being filled a few cents too low, granted I think they were talking about options and I barely ever trade options, and poor availability of stocks for shorting, difficulty canceling and modifying orders).
