The charting add-on to one of his offerings was claimed unreliable by the company on whose platform it was running! And the charting add-on (something to do with EW counts) was critical to the 'successful' identification of entry points.
Apart from giving me an inside on the pros calculation models for exotic FX options, the systems peddled so far have been pretty useless. The succession of 'new' and 'even better' hint at soap powder rather than any serious trading system.
Probably a very nice guy, but his forte appears to be developing and marketing systems, each 'better' than the last. It's probably what many of us have done, and do, over the course of our trading career. The difference is, we don't rush out with the promo material for each new indicator we invent.
