A Quant’s Approach to Building Trading Strategies: Part One

Recently, Quandl interviewed a senior quantitative portfolio manager at a large hedge fund. We spoke about how she builds trading strategies--how she transitions from an abstract representation of the market to something concrete with genuine predictive powers. Can you tell us how you design new trading strategies? It all starts with a hypothesis. I conjecture that there ought to be a relationship between two instruments, or maybe there’s a new instrument in the market that’s gaining popularity, or maybe there’s an unusual macroeconomic factor I’ve discovered that drives micro pricing behavior.

An Introduction to Chinese Futures Data

Chinese futures data has always been in high demand among our users. For years, China consumed more commodities than any other country. The current economic slump and "commodities hangover" have only heightened the interest in data on Chinese futures. That's why we're especially excited to offer these new free databases on the four mainland exchanges.

Bring Your Own Tool: the Latest Trend in Data Analysis

The role of the data analyst is changing. The best analysts know that different tasks require different tools. The End of Bundling Once upon a time, data purchases came bundled with data consumption software. You couldn't just buy a dataset; you had to install a proprietary data downloader. You couldn’t just view the data on your computer; you needed a custom visualizer, or even a full-fledged data terminal. And you couldn't do whatever you wanted with the data; you were forced to work within the applications provided to you by the vendor. Today, this seems absurd. In 2016, analysts don't...
