А может есть какой-либо другой способ, как можно узнать количество баров занимаемых в прямоугольником?

Конечно есть. Можно пальцем посчитать на мониторе…))

Для меня не совсем понятно что вы хотите написать. Ну взяли вы время с координат прямоугольника… и что? Вам надо количество баров исходя из этих дат? Ну возьмите функцию Bars() в которой указывается диапахон времени.

можно так

Верхний (синий) зигзаг, рисуется по максимумам

Потому что рисует "HighMapBuffer ",

а обращения к функции zig() вообще нет нигде.
