This indicator significantly expands the possibilities of the usual zigzag due to the addition of parabolic channels at the earliest stage of their origin. 
Download the demo version and test it in the tester. All the graphics in the tester are working.
But the Zigzag algorithm is special here, because it is implemented on the unique author‘s ultra-fast cycle-free algorithm for calculating parabolic regression and calculating its standard deviation.

The features of this zigzag are:

• Fast calculation, independent of the period. Therefore, the gain in speed is especially felt at higher periods
• Two parameters instead of three: the period of the parabolic regression and the coefficient of increase in the value of the standard deviation (the width of the parabolic channel)
• High adaptability to the flat and trend

For ease of operation of the indicator, a new intuitive interface has been developed, which is also designed for touch-controlled screens.

A simple test strategy is also implemented with the display of the Balance chart and the display of transactions on the screen.

• Green circle – Buy.
• Red circle – Sell.

The opening price is strictly in the center of the circle, taking into account the spread
This strategy opens a deal to sell if the newly formed parabolic channel “looks” down and the price crosses the upper border of the channel, and to buy if up and the price crosses the lower border of the channel. The spread is calculated based on the average spread of the last 2000 ticks.

If this indicator is in demand, the strategies will expand.  

I do not recommend using this indicator in the mode of:

•  Max bars in chart: = unlimited.

Please report any errors, they will be promptly resolved. 

In the future, an Auto-adjust button for the best parameters will be added.
