Nifty weekly charts is preparing for a test of new lows?

nifty is almost over sold on daily charts while on weekly is bearish conti., Here if get support from global markets , a technical bounce cannot be ruled out in that case key areas to look out for will be roughly 16300-350, 16500-600, 16830-900 zones on upside .. while on down side near term supports are placed @15550-15300-15000 areas.. eventually it seems like nifty can test sub 15K level there as of now key area seems is between 14500-4250 zones.
