Hi Adam, Re: execution,
That's a good point.... I read the bids on Level 2 to make sure there's enough to cover my sale without driving the price down... On the other side I've had market makers buy or sell me 1 share, which trips a GTC commission, and then take the price 20 cents in the other direction... Also by putting "All or None" I've had my orders skipped around and ignored and not executed... Besides, as crooked as Wall Street trading is, I don't like to have my cards on the table with GTC orders... I'd rather just hit'em with a market order... Plus it saves me $5 bucks.... Grin
Profit from your ideas!
