AlterGrid v2 - индикатор для MetaTrader 4

Основан на индикаторах KeyLevels и TimeZones.

Отключает встроенную сетку MetaTrader 4.

Рисует "круглые" ценовые уровни и разделители.

Изменения в версии 2:

• добавлена реакция на изменение масштаба графика;
• разделители времени убраны на задний план;
• добавлен выбор стиля линий.
