Association of National Exchanges members of India (Anmi), a broker body, has written to the market regulator saying there was no timely public announcement by NSE regarding Wednesday s technical glitch, which has caused a huge monetary loss to members and investors, including intraday traders. All open positions remained at peak levels. The glitch happened one day before the expiry of monthly and weekly contracts. Hence, there is a greater need of engaging deeper investigation in the matter, Anmi said in a note on Thursday. The body further said that trading could have continued since there was an issue with two spot indices and all other things were working fine. Reasons for not activating recovery site even after 45 minutes of glitch also remained unknown.
