What is the best stock trading simulator site for free?

I am trying to learn day trading and I have initially tried the trading simulator provided by investopedia.com; it was good, but now I opened a real account and it turns out that I did not learn much, the real brokerage account is totally different: margins, monthly statement, P&L reports… So I am now looking for a stock trading simulator (preferably for free) that has all these features of a real brokerage. Any suggestions?

Will Raptor CEO David Karuri consider an IPO offering in 2012?

While there is a lot of volatility in the stock markets, one cannot seam to wonder why a company with so many projects under Research and Development (R&D) does not seek private equity funding through an Initial Public Offering?

Why is the stock market most recently responding by hugh volatility from report's not bottom line profit or lo?

It seems every other day some person or persons either in gov or private sector issue reports that cause market to bounce-is it possible for people to manipulate the market this way & would it be to the advantage of the professional traders and insiders and not the sophisticated investor?

question on Implied volatility for options?

Hello everbody,
Please read the following and i have listed my question below after the content.

CONTENT:
EVENTS THAT CAUSES SURGE IN IMPLIED VOLATILITY:

INDIVIDUAL STOCK:

-New product announcements, FDA announcements, Industry specific News
-Talk that a company might announce better or worse than expected earnings
-Takeover Rumors, News of Management Change, or stock split
-Accounting Irregularities and corporate fraud

MARKET WIDE:

-Aggresive Put Buying
-Hedging Unusual events such as war, Political Uncertainity, Fear of market crash, Change in Interest rates
-Economic Events, Contagion, Fed announcements, irrational exuberance.

QUESTION:

1.First of all, what is meant word"SURGE" listed in above content?Does it means Rapid Increase or Rapid Decrease?I am confused…Please make me clearer and give examples if you can.Please explain to me in clear simple way.

2.i asked many people and they said "surge " means increase.Ok now my question is: Lets say aggressive put buying (listed above in market wide) causes surge in IV.In this case, surge in IV means increase in IV .Now, increase in IV means high option premiums (for both call & put) & stock price is seen as bearish because of High IV.AM i correct here?
………Continues……..
so now, decline in stock price decreases call premium and increases put premium.Am i correct here?
……..Continues…….
Since IV will increase because of aggressive put buying( I assumed word" surge" means increase) it will increase both call & put premiums……

am i correct here?I am confused with the word "surge".iS IT INCREASE OR DECREASE IN IV?

Please explain to me in simple and clear way.

Does anyone know where or how to get equations that model the stock market indexes over time?

I’ve been working to get a model equation that reflects expected index prices, so I can calculate deviation and predict major rises and falls. I’ve been working mainly with the Dow and S&P, but have yet to find an equation that has the degree of accuracy I’m looking for. I have attempted both compounding and logarithmic equations (and weighted for both), and though they are extremely indicative, they are based on many assumptions of where the indexes should have been starting and where they should be now. Attempts to use midpoint averages have not worked out as I’ve wished. Despite this, my models are accurate enough to prove its possibility, and show volatility very clearly and indicate crashes (in the past) very well. I’m trying to find an existing model that does what I am attempting, for ANY index, so I can apply it for the next few years (especially to indicate when it can rise again to set up long term stocks). This will save me many more hours of work! Thanks for your time

1 Year – Stock Market Predictions In S&P 500 (Look @ my Math, and give an opinion)?

1. In the S&P 500, the best indicator of Volatility is VIX.
2. The VIX indicator is Currently @ .62…
3. Maximum Volatility for 1 month Prediction using VIX = 8.55% (with 68% Certainty, or about 1 Standard Deviation)
4. For each month, the S&P 500 (it can Go UP or DOWN)
5. There are 2^12 possibilities of UP and DOWN months in a year = 4096.
6. Here are the Possibilities Below (Months UP and Months DOWN):
6 UP, 6 DOWN = 924/4096. 22.5% (Near 0% Volatility)
5-7 UP, 5-7 DOWN = 2508/4096. 61.2% (Up to 17.1% Volatility)
4-8 UP, 4-8 DOWN = 3498/4096. 85.4% (Up to 34.2% Volatility)

*** So, within a 58% Overall Certainty, the market will Go Up or Down within 34.2% from it’s current level. Yes, the Market is really that Volatile. And, is my prediction for the next year (based on this VIX level)

What is your Prediction, and opinion? Will it be Up 15% or down 20%, in 1 year time, for example…

Would a 50% drop in the stock market make a 2X leveraged index fund lose its entire value?

I’m curious…let’s say I’ve bought a "bull" fund that mimicks the returns of the S&P with double the volatility. If the market were to drop 50% at some point or another (I know the chances are unlikely), would that make the value of my fund {content}? And if so, how can {content} ever recover? If my fund drops to {content} one day, a 2% increase the next day in the market couldn’t create interest off of zero dollars. See my problem?

Thanks for your help.

How do I get involved in the stock market?

I want to invest but i dont know how much when & where…
Basically, I have little knowledge of how the stock market works, and I just want to get started. What I really want to know is how stocks and the stock market works, how to play the market – things like that. In fact, if there’s recommended reading on the subject for beginners, that’d be great too. Any other advice about particular stocks, or even advice about other preferable investment options, would also be greatly appreciated.
