Description: FFT算法的基本原理是把长序列的DFT逐次分解为较短序列的DFT。按照抽取方式的不同可分为DIT-FFT（按时间抽取）和DIF-FFT（按频率抽取）算法。按照蝶形运算的构成不同可分为基2、基4、基8以及任意因子（2n,n为大于1的整数），基2、基4算法较为常用。-FFT algorithm is the basic principle of DFT successive long sequence is broken down into shorter sequences of DFT. In accordance with the different extraction methods can be divided into the DIT-FFT (time taken) and the DIF-FFT (according to the frequency of extraction) algorithm. In accordance with the composition of different butterfly operations can be divided into base 2, base 4, base 8, as well as arbitrary factor (2n, n is an integer greater than 1), radix-2, Radix-4 algorithm is more commonly used.

Description: MACD指标(Moving Average Convergence Divergence) 平滑异同移动平均线. 主要是利用长期与中短期移动平均线来计算两者之间的差离情况，作为研判未来行情走势的依据，其中包括了三条线：MACD线、DIF线（是核心）、柱状线 BAR（MACD辅助指标—用红柱和绿柱，其公式为：BAR=2×(DIF－DEA)）。但要切记：任何指标相对于成交量而言都是滞后的，避免进入纯指标分析误区， 所以任何技术指标不能孤立的使用。-MACD indicator (Moving Average Convergence Divergence) moving average smoothing differences and similarities. Mainly used in long-term and short-term moving average calculated from the difference between the two cases, as judged based on future market trends, including the three lines: MACD line, DIF line (the core), columnar lines BAR (MACD auxiliary indicators- with红柱and the Green column, the formula is: BAR = 2 × (DIF-DEA)). However, bear in mind: in relation to any indicators are lagging behind in terms of volume to avoid errors into the net index analysis, it can not be any technical indicators for the use of isolation.
