In an interaction here, Sinha said regulators across the world are looking to find an effective solution for this menace but have not been able to find anything concrete.
"While Sebi is among the first regulators to have some kind of regulations in place on HFT (High Frequency Trading), there is a need to make it more stronger. We are working on that.
"We have also asked stock exchanges to look into it and put systems in place to stop any misuse. We will soon put out a discussion paper on the entire issue and the final regulations would be framed after taking into account inputs from all stakeholders.
"All the measures that we want to take should be there in the next 3-4 months," he said.

On HFT, Sinha said the percentrage is over 40 per cent in trading volumes, while in case of orders it is even much higher.
On self-listing of stock exchanges, Sinha maintained that
the regulations are very clear on this and an exchange has to list on another's platform.
Asked further on NSE's request for being allowed to either self-list or be regulated by Sebi directly rather than a rival exchange, he said, "Some countries do have Central Listing Authority like structure but that may not be relevant in India and here the stock exchanges must function as front line regulators.
