You can usually afford to let a scenario run for a week
before you commit yourself to any purchases. Bump up the
speed, let the scenario run, then drop the speed to zero
to look over your choices and buy your stock.
Keep some cash on hand for unforeseen opportunities and
to pay your advisors. You don't want to be forced to sell
your stocks before they're ready.
Don't try to concentrate on more than a half-dozen or so
stocks. Focus on one or two sectors at a time.
