Williams %R & RSI with Multiple Periods

Diupdate
DESCRIPTION
1. Calculates %R and RSI with multiple period lengths.
1 period length value is defined by User.
8 period length values follow User's selection of classic number sequences, e.g. Fibonacci, Leonardo, Lucas, Narayana, etc.
2. User selects which indicator and periods to display or hide.

DEFAULTS
%R default custom period: 10.
RSI default custom period: 14.
%R & RSI default number sequence periods: Lucas numbers 11, 18, 29, 47, 76, 123, 199, 322.

CALCULATIONS
%R = (period high - most recent period's close price)/(period high - period low)
RSI = 100 - 1 / (100 + RS), where RS = SMMA(up, period) / SMMA(down, period)

PURPOSE
