In this paper we investigate how high frequency trading affects technical analysis and market efficiency in the foreign exchange (FX) market by using a special adaptive form of the Strongly Typed Genetic Programming (STGP)-based learning algorithm. We use this approach for real one-minute high...

This paper examines the price impact of block trades for all listed firms in the Saudi stock market (SSM) using high frequency data. We find an asymmetric price impact for block trades of 0.5% for block purchases and −0.38% for block sales. However, on average, the price effect of a block...

We employ a special adaptive form of the Strongly Typed Genetic Programming (STGP)-based learning algorithm to develop trading rules based on a survival of the fittest principle. Employing returns data for the Russell 1000, Russell 2000 and Russell 3000 indices the STGP method produces greater...
