Question on documentation

[wildcolor]

I am very new to ta-lib.

Here is a very stupid question about the documentation. Can anyone direct me where exactly is the detailed documentation? For example, the following shows BBANDS has MA_Type.T3, which means BollingerBands will use EMA instead of SMA. But I can't find the description about BBANDS and MA_Type anywhere.....

upper, middle, lower = talib.BBANDS(close, matype=MA_Type.T3)

The best documentation is to look at the underlying C library source code:

http://www.ta-lib.org/

This project is just a lightweight wrapper to allow calling the C library from Python.

Fair enough to look at the C source. But no detailed documentation, API specification etc? Have to look at the source code?

You can search for documentation for the Ta-Lib C library, that is applicable. I have tried not to have too much documentation here since this is just a lightweight wrapper.

Maybe that makes it difficult sometimes, not sure.

Thanks for the reply. But I still can't find a decent official description about the talib functions, eg API specification for BBANDS?

Being one of the most well known library, I feel really puzzled to not to see official documentation...

Maybe you’ll have some benefit from looking at these descriptions and links:

This is where I found a reference to the available MA_Type:

https://fja05680.github.io/TA-Lib-tutorial/

Print the available moving average types

attributes = [attr for attr in dir(MA_Type) if not attr.startswith('__')] attributes $ ['DEMA', 'EMA', 'KAMA', 'MAMA', 'SMA', 'T3', 'TEMA', 'TRIMA', 'WMA', '_lookup']

MA_Type.__dict__ $ {'_lookup': {0: 'Simple Moving Average', $ 1: 'Exponential Moving Average', $ 2: 'Weighted Moving Average', $ 3: 'Double Exponential Moving Average', $ 4: 'Triple Exponential Moving Average', $ 5: 'Triangular Moving Average', $ 6: 'Kaufman Adaptive Moving Average', $ 7: 'MESA Adaptive Moving Average', $ 8: 'Triple Generalized Double Exponential Moving Average'}}

print(MA_Type[MA_Type.DEMA]) $ Double Exponential Moving Average

I also found this site which has a little more info on the functions:
