Dislikedabsolutely no basis why do you have such a concept? i can tell you one thing, robots can trade faster than human beings, and that's it. but being faster, doesn't mean more profitable. on the other hand, wall st robots are very profitable, much more than you and me manual trading. however, it comes with incredibly huge cost/resources. for a random example, to run 1 robot, a fund need to hire 2 ivy league graduates and build a trading channel/link. that alone may be half a million per year to run the robot...... go figure do we have such resources?...Ignored
