Kudos to MMs

I missed this selloff. I was a nose hair away from selling ~1080 SPX yesterday and decided that I was going to wait until later today. Oh well.

As stated many times in this thread, there is a gap fill in the 1080s to about 1100 from the implosion a year ago that will eventually fill.

The Chinese and Japanese are on the March to September quarterly cycle. This can cause currency moves as this period comes to an end, and it is probably at least partially historically responsible for many of the September selloffs.

I think we see a small pop into the 1 CT hour and then probably continue lower. So probably see ~1055 SPX, and then lower again.

Options Market making is super tough now for the electronic options markets. If you have the means, it is still ok, but 95% of the traders at the CBOE are clueless about technology. That is why options MMing is dominated by the big houses now.

I am working on my own Mass Quoter. It may take me forever, but when I am done, I will be able to compete without spending a small fortune to lease canned software that doesn't work.

You'll likely never get to the finish... This is why:

The more time you spend working on the tool, the farther away the target moves. 4mm quotes/second by Jan 2011.
