Based on the two green lines, I would set my Short-Sell profit target @ 1450 to 1460 and possible duration that it would take is probably 1 - 2 months.
Let's look at STI.
STI seemingly also breached through the support @ 3300 with HUGE volume (you can see from the highlighted blue circle).
It would be wise to avoid buying any stocks as the whole market sentiment is poor right now. I advise accumulation of battered stocks after the correction during May where the adage "Sell in May & go away" strikes again. :)
