Market Profile
This a brief and rough guide to the concept.
MP provides a method of analysing market action to show the frequency distribution of price action. (a bit like a bell curve, but is usually plotted against a vertical price scale).
The concept proposes that where the action is centred, represents what people see as 'VALUE'.
It is often taken as read that any action which is +/- 1 standard deviation from the centre represents the 'bid' or 'offer'.
So if you want to sell, you want to sell at the offer and if you want to buy, you want to buy at the bid. Because statistically, these prices are some way above or below what others see as 'VALUE'.
Therefore, you will be selling when the market is 'overpriced' and buying when it is 'underpriced'.
It follows that the price will return to or overshoot the VALUE that
has been established and you will profit as a result.
The concept can be used in any time frame.
