This is worst peak-to-valley drawdown % experienced by the hypothetical Model Account for this trading strategy.

This is considered useful information by some people, but it does not suggest that future drawdowns will be smaller than this. It is always possible that future drawdowns will be larger than this amount.

This is the smallest possible starting capital with which you may trade this strategy.

This number is based on the strategy's historical trading pattern. If the strategy doesn't change the way it trades, it is possible to trade the strategy in a broker account using this amount of capital, as long as you set your AutoTrade "Scaling Factor" appropriately. (You'll be able to specify your Scaling Factor -- how big or small to make trades -- when you set up AutoTrading in a broker account.)

In some cases, it is possible to trade a system with less than this amount, but this will increase risk, since it increases the chance that a "expected" drawdown will cause your account to go to zero, preventing any participation in any subsequent profits.

Remember that all trading is risky, that there is no guarantee of profits, and that drawdowns in the future may be higher than drawdowns that occurred in the past.

TPP's Heart-Attack Index is a completely scientific measurement of the probability of your having a heart attack if you follow this strategy with real money.

Just kidding.

Here's what it really is. The Heart-Attack Index is a relative ranking of the strategy's performance during Monte Carlo simulations run by TPP's servers, in which thousands of simulations are run, again and again, and TPP tries to measure the probability of substantial drawdowns based on past performance.

Low numbers are good. High numbers are bad. (Unless you are a cardiologist, in which case high numbers will mean brisk business for you.)

Remember that even a low number here does not mean that the strategy is "low-risk." All trading is inherently risky, and you can lose all your money at any time, despite what a number on a computer screen indicates.

The Profit Factor, also known as the Win:Loss ratio, is the ratio of total dollars of profit divided by total dollars of loss.
