With the recent Fed rate cut… My charts are showing a breakout signal I haven't seen in years. But for now, I'm not rushing to buy gold. In fact, I'm telling everyone I know to hold off. Because I believe there’s a far better way to play this upcoming surge. It's a method that could turn a 1% gold price change into gains like 59%, 118%, or even 228%. And it doesn't involve buying a single ounce of physical gold or even buying any regular gold stock. I've been trading gold for nearly 20 years now and this is my #1 recommended approach for trading gold right now. Most traders miss them completely… But for those who know how to spot them, it takes their trades to a whole new level.If you're interested, check out the recording here while the link's still up.
