Drawdown and Maximum Drawdown?

So we know that money management will make us money in the long run, but now we’d like to show you the other side of things. What would happen if you didn’t use money management rules?
Consider this example:
Let’s say you have a $100,000 and you lose $50,000. What percentage of your account have you lost? The answer is 50%. Simple enough. Now, what percentage of that $50,000 do you have to make in order to get back to your original $100,000? It’s not 50%--you’d have to make back 100% of your $50,000 to get back to your original $100,000. This is called drawdown. For this example, we would’ve had a 50% drawdown.
The point of that little illustration is that it is very easy to lose money and a lot harder to make it back. We know you’re saying to yourself, “I’m not going to lose 50% of my account in one trade.” Well we would certainly hope not!
However, what if you lost 3, 4, or even 10 trades in a row? That couldn’t possibly happen to you, right? (Sarcasm used) You have a trading system that wins 70% of the time, so there is NO way you could lose 10 trades in a row. (Even more sarcasm used)
Well, while you may have a good system, consider this example:
In trading, we are always looking for an edge. That is the whole reason why traders develop systems. A trading system that is 70% profitable sounds like a very good edge to have. But just because your trading system is 70% profitable, does that mean for every 100 trades you make, you will win 7 out of every 10?

Losing Streak

Not necessarily! How do you know which 70 out of those 100 trades will be winners?
The answer is that you don’t. You could lose the first 30 trades in a row and win the remaining 70. That would still give you a 70% profitable system, but you have to ask yourself, “Would you still be in the game if you lost 30 trades in a row?”
This is why money management is so important. No matter what system you use, you will eventually have a losing streak. Even professional poker players who make their living through poker go through horrible losing streaks, and yet they still end up profitable. 
The reason is that the good poker players practice money management because they know that they will not win every tournament they play. Instead, they only risk a small percentage of their total bankroll so that they can survive those losing streaks. 

This is what you must do as a trader. Only risk a small percentage of your “trading bankroll” so that you can survive your losing streaks. Remember that if you practice strict money management rules, you will become the casino and in the long run, “you will always win.”
Let me illustrate what happens when you use proper money management and when you don't...
