Индикатор PivotPoints

[Forex Trader]

Индикатор показывает дневные опорные точки

H, L, C - High, Low, Close предыдущего дня

Рассчеты:
Вычисляется центр вращения так P = (H + L + C) / 3
Тогда Сопротивление 1 уровня R1 = 2P -L
Поддержка 1 уровня S1 = 2P - H
Второго уровня
R2 = P +(H - L)
S2 = P - (H - L)
И третьего
R3 = R1 + (H - L )
S3 = S1 - (H - L)
