RQAlpha 2.0.0

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

According http://docs.julialang.org/en/release-0.5/stdlib/base/#introduction

By convention, function names ending with an exclamation point (!) modify their arguments. Some functions have both modifying (e.g., sort!) and non-modifying (sort) versions.

level 0 functions modify arguments so it may be a better idea to end their name with an exclamation point (!)

When calculating the SMA of index 6 with period 5, it includes index 1, as the sum is inclusive.
However, it should only calculate with indexes 2, 3, 4, 5 and 6.

Solution:
Formula underneath the sum should be k = i - p + 1
