On the chapter about Editable DataTable
we can find this :

This chapter includes recipes for:
    Reading the contents of the DataTable
    Filtering out null values
    Uploading data
    Determining which cell has changed 
    Adding or removing columns
    Adding or removing rows
    Clearable, deletable, renamable, and hideable colum

I think we should keep dependencies in requirements.txt, and we should read dependencies from requirements.txt instead of keep another copy in setup.py.

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

Expected Behavior

Be able to send Web notification with headers.

Actual Behavior

Not supported.

Potential Solution

Add IEnumerable<KeyValuePair<string, string>> headers to NotificationManager.Web:

public bool Web(string address, object data, 
    IEnumerable<KeyValuePair<string, string>> headers) {
}
public bool Web(string address, object data, 
    PyOb

It would be nice to have some general developer documentation for potential contributors to help in cases such as #510, etc.

What are the best steps to take towards accomplishing this? Maybe something similar (albeit not all details needed) to the Pandas developer docs?

I've begun an implementation of this on my fork, basicall

The return documentation says "A list containing the alpha, beta, a t-stat(alpha) for the given factor and forward returns."

I am assuming "a t-stat" means "and t-sta

Formulas for pricing a Barrier option under Black-Scholes model is of interest. (See, e.g., Section 26.9 of Hull(2018), Options, Futures, and Other Derivatives, 9th edition).

The module implementing this method should live under tf_quant_finance/volatility/barrier_option.py. It should support both puts (up-and-in put, down-and-out put) and calls (down-in call, up-and-out call). Tests should be
