Спасибо за ссылку.
Простите, я наверное глубоковато залез, т.к. программирование - это совсем не мой профиль. Передо мной код простого индикатора Parabolic SAR и код звукового сигнала из примера. Скажите, пожалуйста, в какие места я должен его повставлять, чтобы получать звук при возникновении каждой точки? Большое спасибо за помощь!
