The Exp_RD-TrendTrigger trading system is based on change of the trend direction displayed by the RD-TrendTrigger oscillator.

The class is designed for calculation of the technical indicator Double Exponential Moving Average (Double Exponential Moving Average, DEMA) using the algorithm of the ring buffer.

The Prev Day And Floating Pivot indicator.

The trend indicator which draws the boundaries of the channel

A very convenient indicator to confirm any signals of entry to the market

The class is designed for calculation the technical indicator On Balance Volume (On Balance Volume, OBV) using the algorithm of the ring buffer.

The 4-color АО indicator.

The trend indicator. The indicator line of level 50 can serve as the point to determine the trend

The indicator to trail the stop levels

The CSV file was written to write economic news but there was a problem that the Terminal does not distinguish lines, exactly their number when working with the CSV file. That is why I decided to share my solution of this problem.

The class is the simplified version of the CArrayRing class: it has a predetermined fixed size of 256 elements, it is faster, and allows to organize the mini time series, indicator minibuffers, short sized buffers to store intermediate stream data inside the Expert Advisor or indicator.

The second (edited and added) version of the alternative indicator for trend definition based on the breakthrough bars and distance from extremums. The breakthrough levels and size of the previous trends are added.
