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。

最好的,我们一般很难遇到,否则全球通用了,那谁亏呢 |
