I bought 28000 CE at INR 7 and at 3:30 PM the Nifty Bank Index was at 28,064.5.
The premium was only at INR 14, hence trading at a large discount, even after factoring in the 0.125% fees on entire amount charged by SEBI (Which would have added up to INR 7,000 out of a total profit of INR 13,500 approx).
However, i did not want to take a chance and sold it at 3:30 PM for INR 13.6 when the NIfty Bank index was at 28,064.5 and still shows on the chart (ChartIQ in Zerodha)
At 3:31 PM it changed the Bank Nifty close to 28.013.45.
Can someone explain how the Bank Nifty index dropped from 28,064.5 at 3:30 PM to 28,013.45 at 3:31 PM? I use Zerodha and on the chart it is still showing 28,064.5.
