Extended hours trading.

I use two different online services. One being with E*Trade and the other with Fidelity. I am not familiar with any other online provider for trading, so I can not speak to them. I would call and check into extended hour trading as it can not hurt and can really help at times. I have been able to catch some good trades in extended hours, but you also need to remember when regular session starts, it can be an all new ballgame and can swing like you may not expect... good or bad that is.

With Fidelity I have to select a special dropdown item from the menu bar to do extended hours trading. Nicely with them I can trade from 7:00-9:30 AM and from 4:00-8:00 PM; so basically I could trade from 7:00 AM through 8:00 PM if I wanted to and was able to find other traders/MMs that wanted to do it.

With E*Trade I use their E*Trade Pro platform and from there I use the same buy/sell fields, but the only difference in extended hours is I have to change the Exchange selection from AUTO to ARSA or NSDQ. Extended hours with them are from 8:00-9:30 AM and 4:00-8:00 PM.

One thing to note with E*Trade is if you select ARSA or NSDQ as the Exchange to use, then if they actual fill the trades for you, they will charge you an additional $0.005 per share traded. Fidelity does not do this and they actually find the best Exchange to use with no additional cost to you. At least that is what I have experienced in using both of them.
