Now, what's different to the way that professional view his trade in the market to the way you view your trades. Let's discuss
[31]
But now as we turn the corner and start a new year,
[33]
I want to talk to you about a subject that if you fully understand and appreciate the concept,
[39]
It will hold you in great stead for 2018 and the subsequent years.
[44]
This is by far, the most important topic that I've covered in all my Forex videos.
[49]
And I'm also confident in saying that the failure to understand the key principles of what I'm going to explain today is...
[55]
...the number one reason why most traders fail in this business. And that's the law of large numbers.
[62]
Now, before we go into more detail about the law of large numbers, I want to talk to you about probability.
[67]
So come and join me on the whiteboard, and I'll explain further.
[73]
Ok so, "probability" .
[75]
Probability is basically, the statistical likelihood of an event or events happening at some point in the future.
[82]
Now, the easiest way to explain...
[85]
...probability to you is using the common example of the coin toss. So for example, if you have an evenly weighted coin, with heads and...
[93]
...tails as the two possible outcomes, each has a 50/50 chance of...
[98]
...happening. So if you were to toss that coin 10 times,
[103]
the laws of probability state you should get 5 heads and 5 tails.
[109]
But in reality, you may actually get six heads and four tails. You may get...
[115]
seven heads and three tails. You may even get 10 heads and..
[120]
...0 tails. Why? Because the sample that you're using here is such a small sample. You're not giving the laws of probability...
[127]
...enough time to play out.
[131]
Pretty sure, if you toss that same coin 10,000 times,
[137]
you're going to get pretty close to a...
[141]
50-50
[143]
distribution...
[144]
...heads over tails. You may get 51 to 49 or or something like that.
[149]
That's going to be much much closer to what's expected, because now, the sample has gone from 10 to much bigger population of say,
[157]
10,000. You're giving the chance for that probability to play out. So if you put that on a gar for example now.
[167]
It's going to look something like this. So here's the ten sample. Now, every time...
[173]
...you get a head, will go up. Every time you get a tail, you' go down. To your heads, tail, head, head, head, tail,
[179]
tail, tail, head, head, tail. It's gonna look something like that. Pretty, pretty erratic. Not close to the mean of
[186]
50-50 at all. If on the other hand,
[189]
you toss the coin ten thousand times,
[193]
it's going to look much more like...
[196]
...that. Much more as expected on a
[200]
...50-50 outcome. Why? Because the sample size is so small here, that the outcome is a less predictable. On the bigger sample size...
[208]
...the outcome is much more predictable.
[211]
So why is this relevant in our trading? Well, it's very relevant!. Now, presumably,
[216]
you've got yourself a strategy that you've back tested.
[219]
You know what the expectancy is. We know the expectancy on the coin is 50/50. If you've got your stir for strategy,
[226]
and you've back tested it, you should know what to expect going forward.
[230]
So if you understand the laws of probability you won't be throwing out your strategy...
[235]
...just after such a small sample size. You'll be giving it much more time to play out. This forms the very...
[242]
basis of the law of large numbers that we're talking about today.
[251]
Now, the law of large numbers applies to many different walks of life, not just Forex trading.
[257]
Let me give you an example of something you might be more familiar with, like the insurance market.
[262]
I'm sure we've all done insurance in the past bit; house insurance or car insurance, life. Look, let's look at a life insurance,
[269]
So assume you want to get yourself insured you go to the life insurance company,
[273]
and they can ask you for certain information. You might say, I'm 50 years old.
[278]
I'm an a male,
[281]
nonsmoker, and
[284]
quite a healthy lifestyle. So the insurance company , now,
[287]
they employ a group of people called actuaries. Now, the actuaries job is to go back and look at the big population,
[294]
and to come up with a statistical likelihood of where you're back where you're likely to live to. So, for example,
[301]
they might come back and say,okay with all those details. You're likely to live to...
[306]
86 years old.
[308]
Okay, and they will price the insurance policy with that in mind.
[314]
In reality,
[316]
you may die...
[317]
...at 52 years old.
[320]
You may live to 100 years old.
[325]
The point being here is, the insurance company isn't going to throw out all those past medical history,
[332]
all that big population that they've been researching over the years, just because they got one wrong. In reality, chances...
[339]
...are you won't die at 86 years old. This is just a big population...
[343]
...likelihood. So the law of large numbers says, don't worry about the short term.
[348]
Don't worry about minor fluctuations from what's expected.
[351]
But keep with it because the law of large numbers says, in time, the bigger population will pan out.
[357]
This is exactly the same as trading when you're trading,
[360]
you know what the expectancy is. You're not going to throw out the strategy, just because you got a few wrong.
[367]
Let me explain that again,
[368]
using a chart.
[372]
Okay, so you got yourself a strategy you back-tested your strategy
[376]
You know what's expected of that strategy. Remember with the coin toss, you know it's expected return-
[382]
50-50. So this strategy you've run it through your back testing and you're confident that you want to start trading this.You've seen...
[389]
...the equity curve in the back test. Now any equity curve or any chart will normally have the time on the horizontal axis and the...
[398]
...value on the vertical axis. And your strategy expectancy looks something like this.
[407]
Think hey, that's a good strategy.
[408]
I'm now going to start trading this with my hard-earned dollar, and off the bat you start trading and what happens...
[415]
*inaudibles*. You start losing money.
[419]
Hang on, this isn't what I was expecting this has got a positive expectancy this strategy should deliver me a good...
[426]
return on my investment. In reality,
[429]
you don't know if this period here, is in fact, this period here...
[436]
...or this could be this period here of the equity curve or indeed, this period here.
[442]
So you ditch the strategy...
[443]
...or you tweak the strategy, you change it, because it's had this...
[447]
...inevitable losing period. Every strategy will have its losing period, and this is the whole premise behind the law of large numbers.
[455]
You've got to look at your trading in the big picture, not just about the last trade or the next trade,
[460]
but the bigger, bigger picture. Don't get too stressed about the now moment, look at the bigger picture.
[467]
Let the strategy play out you've done your back-testing,
[471]
you know the expectancy, give faith in that strategy, and don't you stir it out, or tweak it because of the inevitable losing periods.
[481]
Okay, so I hope you enjoyed that and indeed, found it useful. Do give me a thumbs up if you did give me a thumbs...
[487]
down if you didn't. I'm big enough and bold enough to accept it.
