I would be happy to go over this type of spread. It's basically a time spread with three, four or sometimes even five different strike's, usually consisting of both puts and calls, and some of the strike's can be ratioed as well(to help the p&l graph). What this does is give the underlying a larger range of motion for profitability as opposed to the single strike calendar. Although it's a bit more labor intensive than the single strike calendar, it has advantages.
1. The 'outside strikes' are typically OTM, and don't cost as much.
2. You have almost effectively taken away 1 of the disadvantages of the calendar(movement of the underlying) thus you only need to worry about your vega exposure(decreasing volatility). (yeah, i know, i know gap risk is still there, but for simplicities sake, u get the idea)
Let me give you an example. In late December, I thought a BMC software 22.5 call(jan/may) calendar looked juicy. After IV went up sharply, I figured directional risk could become an issue, so I bot the 25 call cal.(jan/may) and the 20 put(jan/may). I decided to buy 14 put calendars as opposed to my 10 contracts each for the calls(22.5, 25). This is a matter of personal preference & I think it helps the downside of the p&l graph. I am already at breakeven on this position and I still have 2 front month roll opportunities. The only thing I don't like here is that earnings are this week, and IV is currently at the high end of the range. But still, this position is already paid for so who's complaining?

I expect to roll my short febs sometime late next week or early expiration week. That's basically it. The p&l graph at expiration looks like a big top tent for these strategies, so I guess you could call it a triple(quad) calendar or carnival spread or whatever floats your boat.

I have been focusing on these types of trades as well as double diagonals, and iron condors, because I am sick of having to choose direction in the market

grrr, i've lost a king's ransom in my directional heyday.

I guess I still use it occasionally, but non-directional income strategies are becoming more and more my bread & butter.
I will update when I roll my short strikes.
