The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

First, calculates the fast moving average (usually 12 days) and slow moving average (usually 26 days) by exponential calculation method; second, make fast line value minus slow line value to gain the difference of relative distance. In order to make the trend signals more clear and less influence exerted by of excessive price fluctuation, the difference should be smoothly calculated (general elect 9 days) to get average of difference value. Chart the difference and its average in a coordinate with time for horizontal axis and MACD for vertical axis. Then we can apply the identical, contrary or cross signals through observing their direction, relative and absolute positions.
