Coders Automating Their Own Job

To name just a tiny fraction of things that'd be required for a perfect stalemate between automated stock trading platforms (due to them all being able to predict the market with perfect accuracy):

* actions of any given platform doesn't meaningfully influence the market

* all have ability to forecast weather with 100% accuracy

* all have ability to perfectly predict human behavior

* all acquire the exact same news at the exact same rate

* all connect to the same exchanges with the same latency

* all have the same amount of capital to leverage trades

Simply put, there are incalculable ways for a trading platform to gain advantage over another, so I don't think this will be an issue in many lifetimes.

Yes - this... Buying or selling even 1 share in the markets adds information to this giant calculating engine. Anything you do will alter the course of the future.

I've never seen a backtested strategy that didn't look great on paper. The moment you drop it into the market - you can take a steep discount to your expectations.
