Calculate Demark's Pivot Points:

Tom DeMark’s pivot points are the predicted new high and new low of the current trading period. With tom DeMark's method, current period's trading range is derived from the high (H), low (L) and close (C) prices of the previous period together with the opening price of the current period. Here are rules to calculate Tom DeMark's pivot points:
If Close (previous) is less than Open (current): X = H + 2 * L + C;
If Close (previous) is greater than Open (current): X = 2 * H + L + C;
If Close (previous) is equal to Open (current): X = H + L + 2 * C;
New High = X / 2 - L;
New Low = X / 2 - H
(H: high; L: low; C: close; P: pivot)
