The code is the fibs based on prev day close (could change to weekly, monthly if desired with some modification).

Pivot point studies highlight prices considered to be a likely turning point when looking at values from a previous period, whether it be daily, weekly, quarterly or annual. Each pivot point study has its own characteristics on how these points are calculated. The formula applied for the Fibonacci Pivot Points is:

Pivot Point (P) = (High + Low + Close)/3

Support 1 (S1) = P - {.382 * (High - Low)}

Support 2 (S2) = P - {.618 * (High - Low)}

Support 3 (S3) = P - {1 * (High - Low)}

Resistance 1 (R1) = P + {.382 * (High - Low)}

Resistance 2 (R2) = P + {.618 * (High - Low)}

Resistance 3 (R3) = P + {1 * (High - Low)}
