CCI
(Commodity Channel Index) - Measures the variation of a security's
price from its statistical mean. High values show that prices are unusually
high compared to average prices whereas low values indicate that prices
are unusually low. Default
of 20 periods (minutes, hours, days, etc.)
Historical
Volatility - Reflects how far an equity’s price has deviated from
its average price over the number of periods you specify. This study only
applies to Daily, Weekly, and Monthly charts. Default of 20 periods.
MACD
(Moving Average Convergence Divergence) - A trend-following momentum
indicator using 3 exponential moving averages: a short or fast average,
a long or slow average, and an exponential average of their difference
(the last used as a signal or trigger line). The periods defaults for
the calculation are 12, 26 and 9.
Momentum
- Measures the amount that a security’s price has changed over the last
14 days. If today has not closed yet, it uses the current price for today’s
close. Default
of 14 periods (minutes, hours, days, etc.)
ROC - Rate
of Change - Change in price between
the current price and the close 20 days ago, divided by the price 20 days
ago. Default
of 20 periods (minutes, hours, days, etc.) Technical
study parameters will be configurable.
RSI
- Relative Strength Index - Indicates the degree of positive and
negative movement by the security on a scale of 0 (weakest) to 100 (strongest).
Determined by figuring the ratio of the average up closes for the last
13 days (using today's Current Price for the 14th day) divided by the
sum of the average up closes and the average down closes for the same
period. This ratio is multiplied by 100. The
initial value of an n-period RSI is based on the price action for the
first n periods. Subsequent values are determined using an inductive formula.
Default
of 14 periods (minutes, hours, days, etc.)
RSI
(Adaptive) - Adapts the standard RSI to a smoothing constant. Default
of 14 periods (minutes, hours, days, etc.)
Stochastic
(Fast) - The Fast Stochastic is the average of the last three %K
and a Slow Stochastic is a three day average of the Fast Stochastic. Use
as a buy/sell signal generator, buying when fast moves above slow and
selling when fast moves below slow. The
default for the calculation should be %K-14 periods, %D-3 periods, and
3 periods.
Stochastic
(Slow) - Similar in principle to %D, %D Slow represents a slower,
less volatile indicator that simply adds an additional degree of smoothing,
or moving average period, to the original %D. The default for the calculation
is %K-14 periods, %D-3 periods, and 3 periods.
Williams
%R - A momentum indicator that measures
overbought and oversold levels. The interpretation of Williams %R is very
similar to that of the %K stochastic indicator. The oversold indications
are in the range of -80 to -100, while the overbought indications are
in the range of -20 to 0. The
default for the calculation is a period of 14.
OBV
- On Balance Volume - Relates volume to price changes by adding
volume to a running total when the price closes up for a period, then
subtracts the volume if the stock closes down for a period.
Volume
- Simply the number of shares (or contracts) traded during a specified
time frame (e.g., hour, day, week, month, etc).
