I'm curious, will you be also trading futures spreads?
At some point, yes - I'm quite interested in them thanks to @bone (once you get a taste for derivatives, it's hard to go back.) But not for quite a while yet; I want to get really familiar and competent with the instrument itself - futures - before I get to anything more complex.
Having said that, I've already done a bit of options on futures - have an iron condor in CL right now, which is (or can be thought of as) a pair of intramarket spreads. However, what's missing here is the key element of spread trading in futures: I'm not looking at correlation or cointegration. It's just a standard iron condor - a 1SD bet on vol overstatement - albeit one with somewhat less counterparty risk than equities and a nice R/R ratio, and doesn't actually require understanding much of anything about futures or futures spreads.
In fact... now that I think about it, given how attractive SPAN margin and other efficiencies in futures sound, I'm going to keep doing that. Most likely, I'll run some ICs, flys, and maybe verticals just to see how they do.
(Oddly, my brain seems to file all of the above in the "options" bucket - no relation to the "futures" bucket at all. Probably something about the chart trading aspect of the latter, which is absent/irrelevant to the former.)
