This a peace of a code in VBA (excel) that is much too slow. Can someone (maybe by using another language C++) help me to make this code much faster? Full code in attached excel file. As you can see I first retrieve 1 year or 260 days price data of 100 stocks. And construct all possible 10 stocks portfolio.
VBA code:
nbsec=100
myHighest = -50
y = 0
For i = 1 To nbsec
For j = 2 To nbsec
.
.
.
Next j
Next i
