MACD計算代碼
參數設置為12,23.9
struct Macd
{
Macd():m12(0.0f),m26(0.0f),diff(0.0f),dea(0.0f),bar(0.0f),index(-1){}
float m12;
float m26;

float bar;
int index;
void update(float value)
{

{

}
else
{

m26 = m26 + (value - m26) * 2.0f/27.0f;
diff = m12 - m26;
if(index == 1)
dea = 0.2*diff;
else
dea = dea*0.8 + diff*0.2;
bar = 2 * (-dea + diff);
std::cout<<diff<<" "<<dea<<" "<<bar<<std::endl;
}
