Tasting a great strategy? 1/90 days

I am a fundamental trader who relies on economic data, monetary policy, or events that may affect the economy. However, I have come across a 100% technical strategy that is based on a new style of harmonics that is different from the classics. This strategy promises a high yield and an 80% success rate, which is personally hard to believe. For this reason, I will test it for 90 days to determine if it is true.
