First, to day trade stocks, brokerages will require a minimum account size of at least $25,000. Also, it's a risky game — very few people succeed at it. Those that do have generally become highly skilled at longer-term trading (position trading over several weeks, months or years or "swing trading" over days or weeks) before attempting day trading. There is no software you can use to make your decisions — that is totally up to you. It requires a great deal of experience (I would say, many years) to become a successful day trader.

My experience has been that a "trade" is considered to be the order ans all of its fills. In the attached link, the SEC makes it very clear that a pattern day-trader is supposed to be a real day-trader. Counting each fill would snare too many customers in the net.

From Rule 2520:
"The term "day[-]trading" means the purchasing and selling or the selling and purchasing of the same security on the same day in a margin account"

"The term "pattern day trader" means any customer who executes four or more day trades within five business days. However, if the number of day trades is 6% or less of total trades for the five business day period, the customer will not be considered a pattern day trader"

It's pretty clear to me that to "execute" a trade. I place an order and get fills. The order and the fills are a "trade". Now, if your two "buys" are based upon two separate orders, then the pattern you ask about would be two day trades.

Further info:
Interactiveborkers gives clear examples of day trades on their website. Another reason why I like that firm so much. Looks like your two buys and one sell example is just one day trade.

Day trading is tricky, whether your doing it for real or as an exercise like you are doing here. The primary problem is that over very short periods of time, individual stocks as well as the stock market indexes can be extremely volatile. You might as well throw darts at a dart board marked out with all of the stock symbols because it pretty much is sheer luck over such a short time frame anyway.

I'm not familiar with CNBC's Million Dollar Portfolio Challenge, so I don't know what their investing time horizon is like for this task. Depending on how long that horizon is, I would probably make different sets of choices for your million dollars. Over a longer horizon, I would probably do some research and then pick 20 stocks, $50,000 each, and then let them sit there and do nothing for several months as that is, historically, the best way to get a return on investment. Too much "in and out" of the market would kill you on commission costs alone anyway.

Day trading is very risky and you should only try that with extra income that you can live without. Since you are asking this question I know you are not qualified to trade at that level. Most brokers will want you to have at least $25,000.00 deposited in your account before you can Daytrade so you need to be aware of that. The stock market can be very lucrative but you must know what you are doing.

Hope this helps.

>>How, with only 10 billion shares outstanding, can XXX be so actively traded at this volume and why would XXX sit at the same price and trade billions of shares, when all press and reports about the company are positive?

The market is at a price consensus or is in a consolidation phase. The bulls and bears are in consensus; no one is more powerful than the other.

You will also find that penny stocks are usually less volatile than bigger value stocks.

>>My take is that someone is deliberately swapping shares, huge chunks at a time, at ridiculously low prices to keep the stock price down? Why go to the expense?

No I doubt anyone would be doing that deliberately. There is no point to such exercise – waste of time and money.

Maybe people who bought earlier at a cheaper price are taking profits and people who are hearing the news are buying in.

Good Luck!

Take a look at marketwatch.com. I was looking at one earlier today and while I was making notes, the price kept changing. It may not be "realtime" but it was surprisingly close just from that example. I don't know if they cover your exchanges, but some of your stuff is traded elsewhere too.

This site will have all the information you need…

It is a good way to make a small fortune — if you start with a large one.
