Technical analysis - a set of tools for predicting the likely change in prices based on patterns of price changes in the past in similar circumstances. The basic basis is the analysis of price charts - "charts" and/or the stock market. 

Levels are a reference point in situations where fundamental factors do not allow a particular price value to be identified as a starting point. They are most actively used in short-term trading, when within the random fluctuations it is necessary to identify prices that are currently "too low" and attractive to buy, or "too high", and when they are reached, it is better to think about selling.

Trend channels are another important analysis tool in the Forex market. A sloping channel allows you to determine the direction of the trend. 

Technical analysis indicators are tools that make certain calculations according to preset formulas based on price chart indicators, and then automatically give the result. Most often, indicators look like graphical constructions (lines, histograms, etc.), which are put on the chart in automatic mode.
