Williams %R & RSI with Multiple Periods

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

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
1. Identify price trends.
