Few questions on pre-market and after hours trading

[DESCENUS]

On scottrade how exactly do you engage in pre-market / after hours trading?

Another thing I'm really confused about-- is the pre-market /after hours price gain / loss any way related to the normal hours trading price?

For example, NVDA:

48.96 +2.63 (5.68%) Aug 29 4:00pm ET
Open: 47.37
High: 49.02
Low: 47.20

Let's say this occurs in After Hours:
48.95 -0.20

If you were to purchase 1000 shares of NVDA at this time what price are you getting it for?

The other part I'm confused about is in pre-market hours.

Let's say this occurs during pre-market:

NVDA = 46.67 +2.00

If you buy at this point, what price are you getting the shares for?
Also, when the market opens and the stock goes up do you start from a break even point or do you keep whatever was earned in the pre-market?

Sorry i'm not really sure how to put down my question but I hope someone can explain how this works or direct me to a topic that explains it. (couldn't find one).

Thanks a lot!

(1) You go to the "trade" tab, then click on "Pre-Market/After hours" tab. You must always enter a buy limit during these two extended sessions. No market orders are allowed.


(2) Yes, pre-market and after hours prices are directly related but during after hours the % gain shown on the live stream quote is not the toal % increase/decrease during A/H session. That is the toal gain/loss during regular market hours.

(3) You would put the order at $49.85 if you decide to purchase the stock at that level(it depends on the bid and ask prices as well).

(4) $46.67. That is the starting asking price for the stock. If the stock rises or falls, depending if your long or short, the % gain/loss is still accumulated for the total day % total gain/loss.

hmm thanks, but still a bit confused about the pre-market.

For example, pre market price.
NVDA = 46.67 +2.00

Would it be possible to get it for 46.67?

And let's say it's still at 46.67 when the market opens. Does it rise/fall from 46.67 or from 44.67?

man i'm really confused now. What i'm most confused about are the closing prices of the previous day and the opening price of the current day.

if you look at the 5 day spread for that, why does it close and open at nearly the same price from august 23 - 28, then there is suddenly a gap between 8/28 and 8/29 ? What happened in between 44.33 and 47.47 ? Was that caused by the pre-market trading?
