The Ncx*.pas in this archive contain some functions to access native informations from Delphi (32-bit) programs that are running in WOW64. WARNING: The units rely on internal (native) Windows NT APIs and data structures... (you should *not* use them for production code) The sample binaries were built with the Free Pascal Compiler (2.2.1). NOTE: If you get an "Internal Error 2002032210" for the NcxTypes unit disable the "Use register-variables" optimization (-OoNOREGVAR).

顾比复合移动平均线概念　顾比复合移动平均线(Guppy Multiple Moving AverAge，GMMA)使用了两组指数移动平均数进行分析。由3、5、8、10、12和15日移动平均线构成一组“短期组”，这组指标透露了市场短期投机者的行为；而“长期组”则由30、35、40、45、50和60日移动平均线构成，它能够反映市场中长期投资者的行为。 这两组指标的相互关系可以告诉投资者更多的信息——当它们相互靠近时，说明投资者和投机者对股票价值达成了共识；而当它们相互远离时，则说明对于价值的认识产生了分歧。一旦短线指标和长线指标同时出现了价格方向的一致变化，则是交易机会来临的重要信号。(Guppy Multiple Moving AverAge)
