Parabolic SAR

The strategy is a type of short-term trading strategy known as scalping, which involves making numerous small trades over a short period of time in an attempt to capture small price movements in a given market. The strategy incorporates two technical indicators, the Parabolic SAR and the Commodity Channel Index (CCI), to generate signals for both entry and exit points.

The Parabolic SAR (Stop and Reverse) indicator is a popular trend-following indicator that helps identify potential trend reversals. It consists of a series of dots that are plotted above or below price, depending on the direction of the trend. When the dots are below price, the trend is considered to be bullish, and when they are above price, the trend is considered to be bearish.

The Commodity Channel Index (CCI) is another popular technical indicator used in trading to identify overbought and oversold conditions in a market. The CCI is calculated by measuring the difference between the average price of an asset and its moving average, relative to the standard deviation of the average price. A high CCI reading indicates that the asset is overbought, while a low reading indicates that it is oversold.

In this strategy, the Parabolic SAR and CCI indicators are calculated without using built-in methods, which means that the strategy itself computes the values of these indicators.

Overall, this scalping strategy appears to be a relatively complex approach to short-term trading that uses two technical indicators to generate signals for entry and exit points, and includes a filter to avoid trading in directionless markets.
