  • A Neural Network based trading strategy [Philipp Kahler]

  • Value Investing: An Examination of the 1,000 Largest Firms [Alpha Architect]

    Among stock investors, a common strategy/belief held is Value investing buying stocks that are relative cheaper on price/fundamental ratios.

  • EDGAR timestamps [Regressionist]

    I need precise timestamp in order to study the market reaction to news. Sadly, the SEC has not joined the exchanges in providing nanosecond timestamps from GPS-synced rubidium atomic clocks.

  • Candlestick Pattern Scanner Functions [Dekalog Blog]

    Since my last currency strength candlestick chart post it seemed to make sense to be able to scan said charts for signals, so below is the code for two Octave functions which act as candlestick pattern scanners. The code is fully vectorised and self-contained, and on my machine they can scan more than 300,000 OHLC bars for 27/29 separate patterns in less than 0.5 seconds. Both functions have a

  • Feature Selection (1 / 3) [Tr8dr]

    I am often confronted with the problem of trying to reduce a high dimensional feature set to a, smaller, more effective one.
