New framework for algo trading on cards

New framework  for algo trading on cards
Sebi will soon issue a consultation paper seeking market feed back
The Securities and Exchange Board of India (Sebi), in consultation with the finance ministry, is expected to reissue fresh guidelines on high frequency trading (HFT), popularly known as algorithm trading, after taking feedback from market participants.
According to sources, the earlier proposal to tighten the algo trading rules, which had been put out by Sebi in August 2016, has been dropped by the ministry.The market´s contention was that the rules were framed without taking all aspects into consideration, were not in line with global practices, did not have sufficient checks and balances, and would have had an adverse impact on liquidity.
To review the proposed norms, Sebi constituted in August last year a committee on fair market conduct to suggest measures to improve surveillance of the market and strengthen the rules for algo trades.“We have received several proposals and will soon put out final guidelines in this regard,” said a person privy to the development.
“Sebi´s new proposal would bring standardisation of the colocation (colo) facility.Most of the measures proposed earlier were regressive in natureThe new framework would be progressive in terms of equitable access without impacting liquidity,” said a source.In 2015, Sebi began investigations after it received multiple complaints that some brokers had allegedly got preferential access to the National Stock Exchange´s (NSE´s) colo facility.
According to the source, the consultation paper is being prepared keeping in mind the best global practices and considering cost benefit analysis, which was not effectively done in the previous proposal.Sebi´s new framework would ensure that liquidity is not impacted.For that, the regulator may put a cap on “order to trade ratio” to give level playing field.
This could be done by formalising market maker scheme.“To improve liquidity, the regulator should formalise the marketmaking scheme.There should be differentiated treatment and regulation in terms of market participation.The regulator should economically incentivise market makers rather than disincentivising all market participants uniformly,” said Harjeet department affairs, ministry of Under the revised regulator is said to on a real time surveillance system so that it could minute by minute of algo trades and, thereby, detect and prevent malfunctioning.
PROPOSED MEASURES
To have realtime surveillance of all orders and trades
To detect malfunctioning while putting algo trades
To mitigate chances of ´flash crash´ and fatfinger error
Standardisation of colocation facility to discourage preferential access
Exchanges to publish colobased latency on their platforms to have equitable access
Formalise marketmaking scheme by capping ´order to trade´ ratio
Differentiated policies surrounding this ratio would reduce chances of squeezing liquidity
This could be done by improving the existing infrastructure and ramping up the systems by having an advance template of superior technology.
Currently, there is no structured data available at a prescribed time interval to provide realtime feed for surveillance.Besides, Sebi also wants to have standarisation of colo facility, so that all participants would have fair and equitable access.“ Publishing real time colo based latencies would help bring in transparency as well as provide benchmarking against global exchanges,” said Singh.

The regulator is not in favour of allowing retail participation in HFT at present.“It is not advisable as it would be highly risky for individual investors to use automated trading systems.The regulator wants to have guidelines in place first and it could perhaps consider domestic individual investors at a later stage,” said one of the sources cited above.
Sebi also plans to address and mitigate the chance of flash crash and fat finger trades.Algo trading is a software programme designed to execute automated trades on fulfilment of certain criteria.These are typically trading strategies that make use of complex mathematical modelsThe most common is arbitrage, which tries to profit from differential pricing of the same security at the same time on different exchanges.
According to the Sebi data, a little over 80pecent of the orders placed are generated by algorithms.Such orders contribute to about 40percent of the trades on exchanges(not all orders result in trades).There view of the HFT regulation was triggered by the NSE colocation controversy, where some brokers and officials allegedly made illegal gains through preferential access to the server.
After the controversy, Sebi had published a discussion paper and had proposed seven ways to level the playing field between HFT traders and others.These included revising the order sequence, introducing a minimum resting time between HFT orders, and uniform access to market data

Data storage norm splits digital payments industry

Data storage norm splits digital payments industry  India’s nascent digital payment industry could be thrown into disarray due to the demand by the Reserve Bank of India (RBI) that all user data be stored within the country, fears an industry grouping, which has termed the decision as “heavy-handed”, even as others, including the country’s largest digital payment provider Paytm, have hailed the move.  In a bid to narrow the growing schism, the industry is planning to send a formal representation to the regulator highlighting its concerns, a top official told ET.  “We are trying to build a consensus on the issue," said the person adding that the representation to the central bank will be ready this week.  RBI on April 6, mandated all payment companies—global and local—to set up data storage facilities within India by October. The stringent six-month deadline has attracted the ire of several sections of the industry that fear it will lead to a disruption of wel...

E tailers global warehouses may come under tax net

By
E tailers  global warehouses may come under tax net Warehouses of e-commerce companies based in countries such as Australia, Japan, Italy,  Spain, the Netherlands, and Russia may not be exempted from paying the income tax in India  once the multilateral instrument (MLI) to prevent base erosion and profit shifting (BEPS)  comes into force. BEPS refers to the reporting framework mooted by the Organisation for Economic  Co-operation and Development (OECD) and signed by over 100 countries, including India, to  prevent exploiting gaps and mismatches in tax rules to shift profits by multinational  companies (MNCs) artificially to low-tax regimes. The representatives of 68 countries on June 7 this year signed an agreement (MLI) in Paris  to amend their tax treaties to bring them in alignment with measures to prevent BEPS.  However, there is still time for synchronising tax treaties with the multilateral  instrument. India has submitte...
