The number of indicators is more than 150?

[r-matsuzaka]

In the documentation, there is

Includes 150+ indicators such as ADX, MACD, RSI, Stochastic, Bollinger Bands, etc.

So I counted the number, then I got 132. Where can I find other indicators?

Thank you very much! Do we need fix documentation?

That's not a bad idea. I initially miscounted, there are 160 in the source code. The additional 28, with descriptions taken from the source, are:

ACOS | Vector Trigonometric ACos
ADD | Vector Arithmetic Add
ASIN | Vector Trigonometric ASin
ATAN | Vector Trigonometric ATan
CEIL | Vector Ceil
COS | Vector Trigonometric Cos
COSH | Vector Trigonometric Cosh
DIV | Vector Arithmetic Div
EXP | Vector Arithmetic Exp
FLOOR | Vector Floor
LN | Vector Log Natural
LOG10 | Vector Log10
MAX | Highest value over a specified period
MAXINDEX | Index of highest value over a specified period
MIN | Lowest value over a specified period
MININDEX | Index of lowest value over a specified period
MINMAX | Lowest and highest values over a specified period
MINMAXINDEX | Indexes of lowest and highest values over a specified period
MULT | Vector Arithmetic Mult
NVI | Negative Volume Index
PVI | Positive Volume Index
SIN | Vector Trigonometric Sin
SINH | Vector Trigonometric Sinh
SQRT | Vector Square Root
SUB | Vector Arithmetic Substraction
SUM | Summation
TAN | Vector Trigonometric Tan
TANH | Vector Trigonometric Tanh

NVI and PVI here are stubs and do not contain a real implementation. They always return 0-length result arrays.
Others are rather mathematical functions than tech indicators. Internally they belong to groups "Math Operators" and "Math Transform"

[r-matsuzaka]

Thank you. Then correct sentence is like this?

Includes 160 indicators such as ADX, MACD, RSI, Stochastic, Bollinger Bands, etc (132 technical indicators plus 28 mathmatical operators).

[mrjbq7]

I feel like I copied the text from ta-lib.org, but now that I look they seem to have raised the number!

https://ta-lib.org/

Includes 200 indicators such as ADX, MACD, RSI, Stochastic, Bollinger Bands etc... (more info)

I’d be happy to merge a PR that makes it more accurate!

I will try to survey and categorize the rest of the indicators.
