As per SEBI, trades being reversed on the same day with the same parties with whom they were matched earlier are considered non-genuine trades. These are known as reversal trades.
These reversal trades are usually executed in illiquid contracts with a view to create artificial volume in the market.
These reversal trades are alleged to be non-genuine in nature as they are executed in the normal course of trading, which leads to a false or misleading appearance of trading in terms of generating artificial volumes
MCX has also defined abnormal or non-genuine trades as those transactions executed by the same set of parties at abnormally high prices that have no correlation to the underlying spot or futures price of a contract.
