Purpose

The indicator can be used for manual or automated trading within an Expert Advisor. For automated trading, use any indicator buffer of the double type:

Heiken Ashi prices: Low or High - buffer 2. If the value of buffer 2 > buffer 3, then buffer 2 contains High price, otherwise, buffer 2 is equal to Low price.
Heiken Ashi prices: High or Low - buffer 3.
Heiken Ashi prices: Open - buffer 4.
Heiken Ashi prices: Close - buffer 5.
Highest level - buffer 6.
Lowest level - buffer 7.

Intermediate levels should be calculated using a step that corresponds to a half round or round price values considering the accepted Digits_Accepted parameter, as well as considering the highest and lowest levels obtained by examining the values of the indicator buffers on the corresponding bar.

For the indicator to work, there should be at least ten bars available for the financial instrument. Otherwise, it will show an error message suggesting to update the price history data base.
