The Iranian nuclear deal may catch Oil and Gold investors in a Bear Trap. Initially it will be very negative for both - Oil and Gold should drop - as war fears had built a risk premium into these assets. When Oil gets and stays below $90 it should spook a lot of other markets by raising Liquidity issues. It is after that we may see a bear trap as bears pile on the dropping assets. This will, however, unfold slowly.
Yves Lamoureux sent a message to that effect, and will follow up with more specific recommendations. His chart on Gold shows the coming drop as a fifth wave down, indicating end of trend. He also expects it to show capitulation, necessary prior to a trend change.
