I was first introduced to Market Mapping close to 25 years ago. A friend of mine told me he knew a guy who was making a million a year trading the S&P 500 futures by matching on his screen to prior day trading chart transparencies (you'd hold the transparency up to the screen until you find a match, and then trade it). This was back when laser printers were first created. I asked my friend if he could introduce me to the trader and both parties agreed to set up a meeting. So, I was introduced to Bob and Market Mapping. Bob was very open to sharing what he was doing and from that day forward, I became obsessed with Market Mapping.
