If you recall, we use an average of the closing prices to determine the reference value from our auction. Most of you will think: " I´ve seen this before, same concept as the moving average I use in my trading". Not quite the same. Take a look at the picture below and we will talk about.
So what we did in our example was to use an average of prices to find the reference point, but in fact, value is determined by price x time x volume. The longer time stay at a certain price and the more volume is done at that price, the closer value will be to that price. We´ve come up with that conclusion in our previous articles.
You will now be introduced to Market Profile. What it does is to organize the information obtained by the auction process in a way that we can understand and measure price x time x volume. Once data is organized this way, a normal distribution of prices structure appears. The fun part is, you can apply the same concepts of a normal distribution into this data to make sense of it.
By using the normal distribution, you can define what is value. I use 70% of it´ss area because this is the default parameter used when Market Profile was created. This is why you don´t need to know the reasons of different plays have to buy something to determine value. You determine value by watching what prices they are willing to pay and organizing it in a way you can understand it.
It is now easier to see when prices are expensive or cheap, in relation to value. You probably asking yourself: why the heck is this information useful? Remember what a good deal is? To buy something that is lower than it´s current value (cheap) or to sell something higher (expensive) and buy it back when it comes back to value?
