Technical analysis essentially serves two main functions:

1. For Identification: It identifies and describes past and present price action. It serves as a historical record of what has transpired in the markets. It provides a descriptive representation of market action. This allows the market practitioner to observe how the market has performed in the past, which includes its average volatility over a specified period; its highest and lowest historical price extremes; the common areas of consolidation, average duration, and price excursion of trends; the amount of liquidity and participation in the markets; the average degree and frequency of price gapping; the impact of various monetary economic announcements on price, and so on. This information is especially critical prior to any investment or trading decision.

2. For Forecasting: Once a particular price or market action is identified, the practitioner may now use this information to interpret what the data actually means before inferring future price action. This inference about potential price action is wholly based on the assumption that price patterns are repetitive to some reasonable degree and therefore may be used as a basis for price predictions.
