Technical Indicators implemented in Python only using Numpy-Pandas as Magic - Very Very Fast! to Stock Market Financial Technical Analysis Python library MyTT.py
- Innovative application of core tools function,so to writing indicator becomes easy and interesting!
- Calculate technical indicators (Most of the indicators supported)
- Produce graphs for any technical indicator
- MyTT is very very fast! pure numpy and pandas implemented, not need install Ta-lib (talib)
- MyTT is very simple,only use numpy and pandas even not "for in " in the code
- Trading automation Quant Trade, Stock Market, Futures market or cryptocoin exchange like BTC
- Chinese version MyTT Url: https://github.com/mpquant/MyTT
