[ M A R K E T R E V I E W | T R A D I N G T he trading industry is on the edge of its seat. MiFID II may be better known for conjuring up feelings of frustration and confusion, but when it comes to order flow there is a sense of anticipation as participants wait to see where it will land. The rules will see the closure of broker crossing networks (BCNs) in 2018, causing a seismic shift in order flow and behaviour within the trading landscape. Reversion and impact costs will be a massive factor as to where the order flow will migrate to in a post-MiFID II world. - MATTHEW MCLOUGHLIN, HEAD OF TRADING, LIONTRUST This activity will not disappear into thin air though and order flow will have to go somewhere. Where that will be has been a topic of intense debate but as we move into 2018 we now have a clearer picture. Despite the backlash and rumours of firms attempting to circumnavigate rules, it appears as though the European Securities 38 TheTrade Winter 2017 V E N U E S ] and Markets Authority (ESMA) will get what it want- ed from MiFID II in terms of transparency and activity on trading venues. The question was once again thrown up in the air after ESMA proposed last minute changes to the sys- tematic internaliser (SI) tick size regime in November. It said shares traded privately inside banks should be in the same price increments as on public exchanges. In other words, ESMA has levelled the playing field between SIs and exchanges and there is now all to play for in terms of which venues will sweep up the order flow and activity from BCNs in 2018. “BCN activity is around 30% of total daily volume and market participants don’t realise how significant that is,” says Michael Horan, head of trading at Persh- ing. “That activity needs to find an immediate home and those who run the BCNs will suffer from losing that liquidity. The only way to keep it is to rehouse it as a multilateral trading facility (MTF), but that’s very unlikely to happen. The activity will end up with SIs or with the exchanges and that’s how it will stay for the first few months.” The liquidity will not just disappear. People will still buy equities and markets will continue to function. Certainly ESMA has clipped the wings of SIs and reduced the head start the venues once had, so it makes sense to foresee more activity on lit trading ven- ues, but the activity is yet to shift. Some experts have predicted a drop in volumes and order flow during the first few months of 2018 as market participants wait and see what others will do or where they will send their orders. Matthew McLoughlin, head of trading at Liontrust, says it’s understandable that many market
