Hi, I have subscribed to ontick method and the only scrip I have added is BANKNIFTY index. I was saving the previous tick and the current tick. At some time today, precisely at 11.30.05.4773700, BANKNIFTY index price jumped down to 35993.7 from 36039.6. That's almost 40 points jump down. When I looked at the chart now, it doen's show any gapdown. Did this jump really happen or is it due to delayed data I got from your servers?
