When trading the S&P 500 and Crude Oil, I very much swing trade the markets, taking larger moves than I do in FX. In FX, I can tend to be more nimble. This is because the observable volume is extremely sparse in FX. I highly recommend all my students learn to swing trade in orderly markets where institutional investors are predominantly active, such as the S&P 500, Crude Oil, or similar.
This is in line with the practices of all professional trading firms, and will be a much more relaxed way for you to trade. It will allow you to take a sizeable part of moves.
Once training is finished, intraday swing trading also allows you to easily fit trading around other commitments.
