So i can use highest buy price in that year even if i bought shares after i sold them as long as its in same year.
is that correct ?
Eg.
i bought first lot of shares 10 000 shares for $0.10
then in august
then i bought 90 000 shares in December for $0.15
then lets say i sold 10 000 shares in march for $0.7
and then later in march i bought back gain:
3333 shares for $0.55
3333 for $0.60
3333 for $0.65

I hope you understand what i mean by this explanation.


thanks you
