这个是MT4自带的MACd后半部分的源码，烦请老师标注一下上面意思！

if(MacdCurrent<0 && MacdCurrent>SignalCurrent && MacdPrevious<SignalPrevious &&
MathAbs(MacdCurrent)>(MACDOpenLevel*Point) && MaCurrent>MaPrevious)
上面的“ MathAbs(MacdCurrent)>(MACDOpenLevel*Point) ”看不懂上面意思，请老师指教一下，在前面没有“MathAbs”呀，这里突然冒出来。郁闷！

0线下方：MacdCurrent<0
macd指标金叉：MacdCurrent>SignalCurrent && MacdPrevious<SignalPrevious
Diff线向上运行：MaCurrent>MaPrevious

extern double MACDOpenLevel=3;
MathAbs(MacdCurrent)>(MACDOpenLevel*Point)
由于Diff在0线下方，所以MacdCurrent为负数。因此需要MathAbs()取其绝对值。MACDOpenLevel初始值为3；Point随币种、mt4行情服务器的不同，值各不相同。一般在0.01到0.00001之间。
