Yes I agree. I miss more trades than you can shake a stick at because of watching far too many markets. Never has been a good idea. Decades ago the old time traders warned not to do this,but instead become an expert on a maximum of 3 markets and understand them like the back of your hand so if they even flinched you'd know about it. Now with so many charts available bouncing off the walls it's like watching a ping pong game. I guess it's even worse for those that follow all the 'stories' on each market. Thankfully I don't also have that problem.
Here is another spread trade that tends to repeat every year from Dec well into spring. The "Buy Platinum/Sell Gold" trade. Seems to be right on schedule once again. And I've posted the chart on Gasoline that rallies every Feb into late spring as well recently. It often starts off in Dec/Jan and did that again this time. A big pullback in Gasoline in Feb would be nice to see to get on board. There is also an ETF:UGA for it as well as futures. Same with Platinum with the ETF:PPLT/GoldETF:GLD spread. Lots of ways to skin the cat.
