Here is an example of Moore Research's seasonal trades they offer. This one was the free sample of the month. These trades must have been accurate at least 12 of the last 15 times. I don't subscribe but have to get their seasonal trend charts in 3 time frames overlaid so they send this now and again. They come up with a dozen of these along with the same number of spread trades every month for subscribers. Been awhile since I subscribed so can't recall everything they offer.
