You’ve started to rake in regular profits on your poker table, or, if you will, on your regular trade-size.
Common-sense now tells you, that you need to scale it up a bit. After all, you’d still be risking the same percentage of your stack-size per trade. Simultaneously, if your win-ratio remains constant, you’d be allowing your stack to grow at a faster pace.
You move on to a higher table.
Welcome to the concept of position-sizing.
Those who position-size can evolve into huge winners in minimum time. Even though the idea of position-sizing is so central to trading, it is still one of the most under-discussed of topics. We need to thank Dr. Van Tharp for teaching this concept properly.
Think about it. When you win, your principal increases. On the next trade, you then put the same principal percentage at risk like you’ve always done. Because your new principal was more, it allowed you to buy more. Thus, you put yourself on the line to win more.
What’s essential here is also to down-size your position when you are losing. Taken a few bad beats in a row? Move down to a lower table for a bit, man. Allow your stack to recuperate at this lower level and then some before moving back higher. With that, when you’re losing, you start to risk less. Crucial point.
Of the different methods available to you to position-size, here, we speak about increasing trade-size when a new trade starts.
The advantage you enjoy when you’re doing pure equity is that on each new trade, your position-size can pinpointedly be adjusted according to your stack-size. Scale-up, scale down, trade upon trade, as the situation demands. Beautiful.
Why does this work out so beautifully for you?
You see, your system gives you an edge. You are opening your positions on high-percentage winners only. Period. Simultaneously, you are cutting your losses at your pre-defined maximum. You are also allowing your winners to win more. And, you are taking your stops. Even if your system then gives you a 55:45 edge over Mrs. Market, you’re doing great. Over a large sample-size (many, many trades, or for that matter many, many poker hands), your stack will increase with a high level of probability. As it goes on increasing, you keep turning on the heat by increasing your position-size further and further.
What happens then? What do you see?
Something beautiful happens.
Your trading principal (what we’ve been calling stack-size all the time) starts to increase exponentially. Have you seen the progress of an exponential function as one travels from zero to the right on the x-axis (the x-axis here would stand for sample-size or the number of trades taken)? If not, check it out on the net.
A good system should give you a 60:40 market-edge. In the Zone, you’d probably trade at 70:30 or beyond. That’s 70 winning trades out of every 100 taken, and 30 losing ones. Imagine what that does to your trading principal over 1000 trades, if you adhere to position-sizing, let your winners ride and take your stop-losses.
The numbers will boggle your mind.
Go for it.
