32+
*
33+
* This indicator is a volume based indicator developed by Marc Chaikin which measures the cumulative flow of money into and out of an instrument.
34+
* The A/D line is calculated by multiplying the specific period’s volume with a multiplier that is based on the relationship of the closing price to the high-low range.
35+
* The A/D Line is formed by the running total of the Money Flow Volume. This indicator can be used to assert an underlying trend or to predict reversals.
36+
*
37+
* The combination of a high positive multiplier value and high volume indicates buying pressure.
38+
* So even with a downtrend in prices when there is an uptrend in the Accumulation Distribution Line there is indication for buying pressure (accumulation) that may result to a bullish reversal.
39+
*
40+
* Conversely a low negative multiplier value combined with, again, high volumes indicates selling pressure (distribution).

* Chaikin Accumulation Distribution Oscillator
69+
*
70+
* Chaikin Oscillator is positive when the 3-day EMA moves higher than the 10-day EMA and vice versa.
71+
*
72+
* The Chaikin Oscillator is the continuation of the Chaikin A/D Line and is used to observe changes in the A/D Line.
73+
*
74+
* The oscillator is based on the difference between the 3-day Exponential Moving Average (EMA) of the A/D Line and the 10-day EMA of the A/D Line and hence adds momentum to the A/D Line.
75+
* It is helpful for investors to use the Oscillator in order to determine the appropriate timing of trend reversals.
76+
*
77+
* When the Chaikin Oscillator turns positive there is indication that the A/D Line will increase and hence a Bullish (buy) signal will be generated. On the other hand a move into negative territory indicates a Bearish (sell) signal.

* Average Directional Movement Index
12495
*
96+
* Developed by J. Welles Wilder and described in his book “New Concepts in Technical Trading Systems”, the Average Directional Movement Index (ADX) is a technical indicator that describes if a market or a financial instrument is trending or not.
97+
*
98+
* The ADX is a combination of two other indicators developed by Wilder, the positive directional indicator (+DI) and the negative directional indicator (-DI).
99+
*
100+
* Wilder recommends buying when +DI is higher than -DI, and selling when +DI is lower than -DI.
101+
*
102+
* The ADX indicates trend strength, not trend direction, and it is a lagging indicator.
103+
*
104+
* ADX range is between 0 and 100. Generally ADX readings below 20 indicate trend weakness, and readings above 40 indicate trend strength.
105+
* An extremely strong trend is indicated by readings above 50.
