Apples and oranges. A trader is able to define the conditions under which they will enter and exit trades. The above activities you listed contain hundreds if not thousands of scenarios the participant will have to be ready for. In trading, basic software packages can automate signal alerts to order placement even if the trader is not running fully automated algos. Improved reaction time offers nominal value because you will never compete with the algos. I would be interested in hearing from a trader who spent significant time on a simulator and then transitioned to being a profitable live trader. What exactly did they do while trading on the sim? How much time was spent?
