thinking about making the switch from energy, which i feel has become to untradeable, will at least for now. anyway, looking for some good literature and/or brokers to use. looking to trade time, and basis spreads and simple option strategies. focus to start will be on grains(wheat, corn, soybean). i have already done the standard search on the internet and seem to be coming up with an arbitrary list of manuals and books that seem to be quite expensive. so before i start burning my credit card, just wanted to see if anyone on this site had suggestions thank you!
