Sóng trong giá cho Amibroker (AFL)

IMO mức quan trọng nhất trên bất kỳ chỉ số nào là mức trung tính,
trong đó sự tăng giá tương đương với sự suy giảm. Tôi thích nó ở giữa
của khung. Nó chỉ đơn giản là dễ nhìn. Trong DVB, nó ở Zero.

by occaisionally plotting trendlines on it and looking for trend line breaks,
as well as divergence. */
