The Ranchi archer then blanked 17th ranked Russian Elena Osipova 6-0 to cap a perfect three out of three in the recurve women's section, her fourth individual World Cup gold medal.
Overall, she has nine gold, 12 silver and seven bronze medals in the World Cup.
"This is the first time I've won all three medals in a World Cup. I'm really happy but at the same time, I've to continue improving as we have some very, very important competitions lined up," Deepika had told PTI after her triumphs.
Deepika had become only the second Indian woman after Dola Banerjee to grab the numero uno status in June, 2012 after claiming her first individual recurve World Cup gold medal at Antalya, Turkey.
She will be the only Indian woman archer to represent the country at the Tokyo Olympics next month.
