Summary: Because Chase never published his work publicly, it is near impossible to find any of his writings although his name is widely know in the trading community. This is the first time this title has been published to the public.  It’s extremely rare and multilayered trading system written and updated over the course of many years.  We are uncertain if this particular S/D 3 Formula 3-81 system is complete or if there were other update bulletins that we simply don’t have. We’ve done our best to piece it all together.  While we can’t imagine anyone using a system like this off-the-shelf, for students of the markets and bored quants this might be a very fun puzzle to play with.
