With financial market constantly changing, prices are often affected by many factors that we cannot predict its direction easily especially in the market correction. If investors want to make profits, they must find a relatively low-risk entry points. This study is based on Market Profile Theory to use the displacement of point of control (POC) in different trading days to find out the best extremely short-term entry and exit points in financial big data in order to have experiment and analysis. We expect to find knowledge and behavior of the potential market that can help traders to make profits in extremely short-term trading. And at the end of this study, we can refute that Taiwan Index Futures Market conform to the weak form of efficient market hypothesis. This study found that the POC of historical trading day can be the reference and recommendation of entry point. The greatest performance of making profit is using 5-days historical POC to join the experiment. And it shows POC has the characteristic that the most traders accept its price.

A poly(vinylidene fluoride-co-trifluoro-ethylene) piezoelectric polymer is blended with nano particles of titanium oxide phthalocyanine to bridge photoconductive and piezoelectric effects. In this study, a system is examined by in situ synchrotron x-ray to test a three-way piezo-phototronic soft-material design. The sample is heated for in situ phase transformation characterization. The semi-crystalline poly (vinylidene fluoride-co-trifluoro-ethylene) polymer gradually transforms to an amorphous structure. A complementary piezoelectric experiment before and after the heating experiment shows that the piezoelectric performance is proportional to the phase ratio. Secondly, the system is examined to test its phototronic effect. Piezoelectric responses are measured by controlling the light illumination. The positive and negative controls of light illumination which validate this newly-designed system can be modulated by a three-way piezo-phototronic effect. In-situ synchrotron x-ray diffraction experiments are employed to measure the microstructure evolution as a function of applied voltage up to 800 V. We then turned off both the light and the applied voltage to examine the kinetic behavior of the system. There is orientation-dependent anisotropic relaxation. We compared the lattice-strain evolutions. Piezo-phototronic creep is found in the (110), but not the (310) planes.
