My question is: how efficient are these AIs really? Do they significantly improve a trader's overall profit and loss ratio, or is the improvement only marginal?
Absolutely I'm not sure about the reliance of AI on trading though the seem very efficient in delivering well driven results to users but you can't beat up your chest to the fact that they are reliable in making you achieve that. Of a truth to some extent they may have made trading easier and effective in a way but the reliability is what I'm not sure about.
