Stock Trading
When I lived in Canada I was quite active trading equity stocks on the Toronto and American Stock Exchanges.

Artificial Inteligence and trading
2023 - it is still early days but playing around with ChatGPT and asking questions relating to Stock Trading, Trends and MACD the reponses were quite generic. If things develop in a way that many predict the AI systems are going to be able to predict the movement of stock prices. In the same way that automatic trading algorithms have triggered less than favourable results in the past this is likely to get worse as the "layman" will have unfettered access to the markets and statistical data.
