This indicator compares four types of regression (linear, quadratic, logarithmic and exponential) and chooses the one that best fits the data analyzed.

This version:

• Fixed an error in calculating the standard deviation;
• Makes more use of the indicators of MQL4 standard library;
• Improved the functions of calculation of the regressions;
• Frees a buffer. It only uses 3 buffers now;
• Added a Comment parameter to enable/disable comments on the screen.

The changes do not affect the indicator from the visual point of view, however, the values shown on screen are corrected.
