Using pivot points as a trading strategy has been around for a long time and was originally used by floor traders. This was a nice simple way for floor traders to have some idea of where the market was heading during the course of the day with only a few simple calculations.The pivot point is the level at which the market direction changes for the day. Using some simple arithmetic and the previous days high, low and close, a series of points are derived. These points can be critical support and resistance levels. The pivot level, support and resistance levels calculated from that are collectively known as pivot levels.
