Guppy also has another analysis tool-Guppy Reciprocal Line. Now, the Guppy compound moving average and Guppy reciprocal have been developed into data analysis software by many financial software companies, such as Reuters, Metas tock and Omnitrader. Omnitrader, which needs an advanced trading system, only contains the indicators of several world-class analysts including GMMA, and Gubi is the only non-American partner.

Gubi's technical analysis theory can be applied not only to the stock market, but also to other financial markets such as futures and foreign exchange. Guppy has always been full of confidence in his analytical methods. In response to some people's doubts about technical analysis methods, he gave an example: "Predicting the market is trying to predict future price behavior and behavior expectations with high probability. Just like when we are standing at the traffic lights and the green light is on, we can go forward with confidence. Sometimes we are startled by a car crossing the traffic lights, but most of the time these traffic lights are reliable. When you see the indication signal, you can arrange in advance to take action at some time in the future or when a certain situation occurs. "
