本软件是MT4下的指标系统，它将平均震幅通过通道上下轨表示出来，其中轨有三种轨道线：移动平均线（零次回归）、线性回归线（一次回归）、二次回归线（二次回归）。通道类似于布林通道，对通道突破和通道震荡交易有指导意义。同时，在计算轨道时加入了权重。辅助线与中轨线可以组成一套类似于双均线的双回归线交易系统。(This software is an index system under MT4. It expresses the average amplitude through the upper and lower track of the channel. There are three kinds of track: moving average line (zero regression), linear regression line (one regression) and quadratic regression line (quadratic regression). Channel is similar to Brin Channel, which has guiding significance for channel breakthrough and channel concussion trading. At the same time, weight is added to calculate the orbit. The auxiliary line and the middle line can form a double-regression trading system similar to the double-average line.)
