Ah, that makes a lot of sense. I'm still getting a feel for a lot of this. I feel like I've gotten through the panic buy/sell phase, having lost a bit in the process of selling low and buying high a few times, and now the trends and changes are starting to feel a bit more normal/obvious. Your strategy sounds a lot less risky, and still quite lucrative.
Great to hear it's useful for you. I also lost lots of money buying the high and selling the low. It took me 10 years to get some decent results, and I'm still learning.
