Good luck...computer driven (automated, bot etc) trading is actively allowed by the ASX. Insto brokers have servers placed directly in the ASX electronic system allowing for high speed auto trading that will always be able to react to retail trading signals before those retail trading signals have even been able to get to market. IE there's top level sanctioned 'rigging' that is part of the system that is well documented. Just the way it is, would require monumental pressure (ie government legislation) to overcome.
