You get $1000 to buy stocks of the Dow Profits.
The market change can be found here:
You can buy and sell stocks at anytime, you just have to use the current price.
So for example the current Dow change is at +61.72, so using my $1000 I can buy 16 stocks at $61.72, with $12.84 left over. If the Dow change ever crosses zero, you lose all of your stocks.
If the prices are in the negative, just play like they are positive, but remember anytime the price crosses zero you lose all of your stocks.
The person with the most money at the end of the day wins.
Yesterday I ended up with about $2 left, hopefully I can do better today.
