Correlations and trading

Correlation not causation. Ok, we’ve heard that thousands of time before. The difficulty is that we cannot simply ignore correlation if we are trading financial markets. The relationships between different assets and other data is often crucial to forecasting the market. If we were forced to ignore it, you’d end up ignoring so much data…

Criteria to judge datasets

There are McDonalds everywhere. It’s probably the most ubiquitous fast food joint. If you want a burger, and want it quickly, it not a bad choice (double negative intended).

First steps of building quant
