Ray, have you ever traded a stock?

The only way high speed traders can affect the price you pay is if you use a “Market” order.

I have no idea why anyone would ever use a “Market” order.

If you use a “Limit” order, your order MUST be filled at the exact terms you specify, or it cannot be filled at all.

This seems to me to be much ado about nothing. They're talking about pennies, or maybe fractions of pennies per share.

Ordinary people deal in a few hundreds, maybe a thousand or so shares. So that's a few bucks. Big deal.

Broker fees, market fees, etc. far exceed these amounts.

You're going to make money when a stock you buy goes up, like say, 50% or maybe it doubles, splits, etc.

These pennies won't hurt you as much as sell-offs, bad company earnings, etc.

If I want into a stock, I believe it will rise significantly. That being the case, I don’t care about pennies.
