Trade Frauds and Risks

Hello All,
I have a few questions regarding trading frauds which have come to light recently

  1. Do we have more frauds in trading in line with these which can increase risk.

  2. Can someone explain on Wire-Fraud which can happen ( if any) in Indian exchanges

  3. If the options at 3:25 PM is 5p did it move with the index when it hit the target? vaguely remember it ending with 5p only. Can someone verify test case of STT petition
