UPDATE 1-EU lawmaker turns screw on ultra-fast trading
* Ferber proposes tougher high-frequency trading rules
* Takes harder line on commodity position limits
* Rejects ban on commission on products sales (Adds detail, exchanges reaction)

LONDON, March 26 (Reuters) - Banks should be banned from giving outside brokers direct access to markets as part of a sweeping crackdown on computerised high-frequency trading, a European Parliament report said on Monday.
The report was the assembly's initial response to a draft law aimed at reining in computerised or algorithmic trading and other advances in technology which have made it harder for supervisors to see the full picture and control markets.
The European Commission, the EU's executive, proposed the draft law, known as MiFID II, last year and it is now before parliament and EU states for approval, with changes expected.
Markus Ferber, the German centre-right lawmaker who is the "rapporteur" steering the measure through parliament, said in his report that a tougher crackdown on high-frequency trading or HFT was needed than outlined in the draft law.
HFT is seen by some policymakers as having an unfair advantage over other investors. Fast computerised trading also played a role in the "flash crash" when Wall Street blue chips briefly went into freefall in 2010.
HFT traders often use the trading systems of banks and brokers to access markets directly and favour tactics such as inputting many quickly cancelled orders, a technique nicknamed "quote stuffing".
"Your rapporteur suggests a more differentiated approach and proposes definitions for high-frequency trading and a high-frequency trading strategy to identify a particular subset of algorithmic trading, and in addition a ban of direct electronic access," Ferber said in his report.
He defined HFT as trading at speeds where "the physical latency" (or speed of processing an order) of the system for sending orders becomes "the determining factor".
HFT strategy would include four or more elements such as a trader whose servers are next to those of the exchange; a daily portfolio turnover of at least 50 percent; a ratio of orders to trades that exceeds 4 to 1; most orders being unwound on the same day; or where at least a fifth of orders placed are cancelled.
Orders should also stay in the market for at least 500 milliseconds before they can be cancelled, and exchanges should slap higher charges on traders who cancel many of the orders they place, the report added.
HFT has increased volume on many exchanges and the Federation of European Securities Exchanges urged caution on Monday about taking such radical measures.
"We need to do some homework first. I don't think Ferber wants to kill the market but wants to be on the safe side," FESE Secretary General Judith Hardt told reporters.
Other exchange officials said a ban on direct market access and requiring minimum periods for orders would damage liquidity and force people to risk their capital when they don't want to.
All trading platforms should also have "circuit breakers" in place to cut or slow down trading that becomes disorderly, Ferber said, in another lesson from the "flash crash".
NO EQUITIES OTF
The planned new breed of Organised Trading Facility (OTF) platform for trading contracts currently handled between banks should be limited to non-equities, meaning mainly derivatives and commodities.
This would force shares currently traded off an exchange to move onto bourses or similar platforms that are likely to be more heavily regulated than OTFs, a development stock exchanges welcomed.
"I think Ferber's taken the right steps. Equities are much too fragmented and OTFs would have introduced another layer of fragmentation," Hardt said.
But exchanges were dismayed that Ferber wants to harden controls on the size of positions commodity traders can hold, a step policymakers say could help cool what they see as speculation pushing up oil and food prices in recent years.
All commodity derivatives platforms should have position limits, Ferber said. Other controls, such as risk management systems would be "an addition" and not an alternative, as was foreseen in the draft law. Ferber pushes the draft closer to the U.S. rule of pre-set position limits in many commodities.
He also proposes a ban on a person holding more than one executive or two non-executive directorships at different trading venues at the same time.
Ferber rejects a proposal to ban investment advisors from accepting commission on sales of financial products, in contrast to the UK which plans to ban such commissions from 2013.
Other members of parliament are set to challenge some of Ferber's proposals, as will EU states like Britain. The aim is to approve a final text by the end of this year or early in 2013. (Editing by David Cowell and David Holmes)
