Technical Indicators and Related Parameters Performance (Kä ye kek looi)

Base line stability: zero point real time automatic adjustment (eliminating the baseline drift effect), computer takes both the light source emitting signal, and takes the light source extinguishing signal, achieving zero point real time automatic adjustment, thereby simplifying operation and improving the long-term stability of the signal.
