I love quantmod package in R but now I am slowly moving towards python using pandas for my trading experiments. I have searched a lot for quantmod alternative for python but sofar I was unsuccessful. We can use pandas itself for downloading datas from the internet but its the other small functions like Cl,Ad,OpHi,ROC,Delt,dailyReturns etc and technical indicators such as EMA, RSI, MACD,SMI etc I misses a lot. I have found these two packages for technical analysis ta-lib and pandas_talib but both are not a good package for pandas. The former one strips the time series and we have to work with numpy array and the later has many bugs in it. Which library in python(with pandas) is the best alternative for quantmod in R.
