Know anything about them? They have some interesting material and make some pretty incredible (outrageous?) claims about their results...
tell us more about your trading. 99% of traders on this forum do not need to know about higher order greeks
Ild fully agree with you if 50 percent of the 99 percent had a clue to the relationships of 1 st order Greeks...
Yeah, I'll take them seriously when they start posting live trades on sites with 3rd-party auditing...or a CTA uses their approach and builds a track record on somewhere like Autumngold.com. Hypothetical results + claims of hedge fund managers doing great with their software doesn't cut it.
As an amateur retail, whether buy or write, I only look at two numbers: The cost of setting up the trade (single leg cost of call/put), and the underlying at the end of the period. I am unsuccessful trading combinations like spread, fly, calendar, condor ... they require more complex reasonings which I have not mastered.
