Gourgane: Get top quality historical market data and indicators

Hey @abadesi :) We've been developing stock market back testers and trading bots for a couple years now and the biggest challenge has always been to find affordable, good quality historical data. I personally spent so much time trying different data providers just to figure out that some key elements were missing or broken in their data sets (stock splits, dividend adjustments, technical indicators, reliability, missing de-listed tickers, etc.). We ended up working way more on fixing data sets than actually building trading algorithms (which was the goal all along!) so we finally decided to build our own data pipeline once and for all. Since then, we've been happily back testing stock markets and building robust machine learning models using our data sets :) We planned using this data for internal use only, but figured out there were probably other developers and traders struggling to find cheap, quality data like we were. So here we are, offering historical market data bundles with a one time fee - just enough so we can cover the infrastructure cost.
