Technical Indicators

Stock market data is usually prices for a particular stock. For each epoch of time, the max, min, volume of trade, and final price for the day is listed. An adjusted price may be listed at extra charge (accounting for stock splits). More information can be derived from these prices through the use of technical indicators (TI). TIs are measures to describe the trading activity of a security. The following are examples of properties TIs measure:

  • Trend (price going up, down, nowhere)
  • Momentum (price will go or down very hard or soft)
  • Volume
  • Volatility

Below is a small informal review of TI libraries from github:

Each library implements the same pattern, a long list of functions that takes as input the requisite data and outputs the numerical value for the technical indicator.
