Diksha, who in 2019 became the second Indian after Aditi Ashok to win on the Ladies European Tour, had shot 2-under 70 in the first round and is now 6-under.
Meanwhile things did not go as well for Tvesa Malik (71-74) and Astha Madan, who are set to miss the cut.
While Tvesa is 1-over and the cut is likely to fall at par, Astha after her first round 83 is virtually sure to miss the cut.
Earlier this month Diksha finished T-6 at the Amundi Czech Ladies event, which was part of the LET Access Series (LETAS), one rung below the Ladies European Tour.
Spaniard Nuria Iturrioz shot 66-68 to take a one-shot over German Leonie Harm (69-66) and Thai Atthaya Thitikul (68-68) and German Sandra Gal (68-68) are tied third.
