BandTrader
这是一个债券交易策略。由2条交叉线产生交易信号。( This MATLAB function implements a simple band trading strategy. A band
consists of two lines that form the upper and lower boundaries of the band.
The upper and lower boundaries are used to to enter and exit trades.
For example, if prices fall below the lower boundary a buy signal is
generated.
