The Ultimate Oscillator was developed by Larry Williams. It uses the averaging of three oscillators with different periods.
The Stochastic Oscillator compares where a security’s price closed relative to its price range over a given time period.
The Standard Deviation (StdDev) measures the market volatility. This indicator charactrizes the scale of price changes relating to the Moving Average.
The main point of the Relative Vigor Index Indicator (RVI) is that on the bull market the closing price is, as a rule, higher, than the opening price.
The Relative Strength Index Indicator (RSI) is a price-following oscillator that varies between 0 and 100.
The Price Rate of Change (ROC) reflects this ondulatory movement like an oscillator, measuring the difference in prices in a certain period. ROC grows if prices grow and drops along with them. The more the price change is, the more ROC changes.
The Price and Volume Trend Indicator(PVT), like On Balance Volume (OBV), represents the cumulative sum of trade volumes calculated considering close price changes.
The Price Channel Indicator draws the price channel, its upper and lower boundaries are determined by maximal and minimal prices for a certain period.
The Parabolic SAR Indicator was developed for analyzing the trending markets.
The Moving Average of Oscillator (OsMA) is the difference between the oscillator and its smoothed value.

The ColorCandlesDaily indicator draws candles with different colors depending on the day of the week.
The Market Facilitation Index (BW MFI) is the indicator which shows the change of price for one tick.

The Detrended Price Oscillator eliminates the trend effect of price movement. This simplifies the process of finding out cycles and overbought/oversold levels.

Chaikin's volatility indicator calculates the spread between the maximum and minimum prices. It judges the value of volatility basing on the amplitude between the maximum and the minimum. Unlike Average True Range, Chaikin's indicator doesn't take gaps into account.
The Chaikin's Oscillator (CHO) is the difference of moving averages of Accumulation/Distribution.
