Hi Glen
A couple of years ago I researched level 2 and drew a definite blank - for me anyway. I’m not sure how research you’ve done on Level 2 but if its not much, this might help. On the other hand, I’m no expert and if anyone thinks I’m talking rubbish fell free to correct me. These are just my thoughts and conclusions and I’d welcome more info on Level 2.
When I looked into Level 2 there was a whole lot of info at that time regarding "following the Ax", reading the depth of the market, being able to judge when support was evaporating or arriving etc etc. And as Iraj says, there are no shortage of coaches more than willing to show you how easy it is to crack this type of trading - for a hefty fee - but of course for a fee that is just a drop in the ocean when compared to the riches which will come your way after you have signed up and if you are not prepared to part with a mere £1,000 or two to get the very best of advice how serious can you really be!! We are given numerous examples of trade set ups showing spectacular results using sure bet set ups.
But somehow non of these experts risk their reputation by live trading - not even for a short time. All sorts of excuses are given and you are made to feel you are calling their integrity into question if you want proof of their practical trading success before parting with you hard earned cash.
Here’s a screen shot of my esignal Depth of Market screens for RIMM for part of today.
You can see at the bottom of each window how many different “Depth of Market” screens - there are - Level 2, Total View, Regional, SingleBook, Arca etc etc. Take the middle window marked as Level 2 by the green light on the bottom left.
The 5th row to the right shows chxe has been at the inside bid 52 times since I opened up the screen. cinn has been at the inside 13,480 times. The problem is that all the lower case MMIDs are ECNs rather than Market Makers. MSCO and TMBER and FBRC are the only Market Makers who have been on the inside bid and only 11 times out of 26,000!! I’m a bit out of date but when I researched level 2, NASDAQ had set up a MMID symbol named “SIZE” which was where Market Makers could hide their orders anonymously. All you would see in Level 2 was SIZE and not who the market maker was. I think this must have changed to NSDQ – perhaps someone could confirm this.
So where’s the Ax. Its quite plain that all the MMs are using ECNs or NASQ to hide their identity and for this stock at this time there is no visible Ax. I don’t see why there ever would be now, since hiding your intentions is so easy for any MM.
So you cant use Level 2 to find out who’s buying and selling. So what about the real depth of the market. Unfortunately anyone can hide their order so when cinn shows 400 on the inside Ask it might be that Morgan Stanley (MSCO I think) has a further 10,000 hidden through cinn at that price and that if you were to look at the deals going through you would see trade after trade going through the ask at 118.76 and the Level 2 still showing cinn standing at 4. There is now way you can judge when cinn’s supply at 118.76 is going to run out and the price moves on to arca at 118.76 (who might also have a further 10,000 placed by Morgan Stanely but hidden!!- who knows).
Also you can see that arcx has 500 sitting at 118.73 on the bid. But if you look at the right hand window which gives all arcx orders, you can see that it also has 600 at 118.72 and 300 at 118.71. These bids which are off the best bid for this ECN are not shown on the Level 2 screen. The same applies to all the other ECNs which have their own order books and depth of market. Only the best bid and ask are shown on the level 2 screen. So to get a true depth even without worrying about “hidden” quotes you would need to combine all the Level 2 quotes with all the ECN quotes. Given the huge traffic now going through the ECN books I think this truncating of the depth must surely have a devastating effect on trying to trade using “Depth of Market” as a guide.
NASDAQ in their wisdom also acknowledge that Level 2 is pretty useless for judging the true depth of the market so they brought out “Total View”. Total View is supposed to show the true depth. I’ve never really worked out just what it does. Sure, it shows the added “visible”quotes by NSDQ but I don’t think it shows any hidden orders and it certainly does not show ECN depth.
Another problem, for me anyway with Level 2, is that the average trade size has dropped from over 2000 shares in 1990 to under 500 in 2003 and I think must be even smaller now with the advance of algorithmic trading being used to break up large orders into small packets to ensure minimum effects on prices when working large orders. This makes any Level 2 screen for a suitably liquid high volume stock so quick I’m left at the starting block studying one of these screens while the other screen moves against me in picoseconds. I took the view that even if there was a way to decipher Level 2 profitably it would take me way more than a days coaching at £1,000 to master it.
As I said, I’m no expert and this is just my opinion. It could be that my understanding on hidden orders and depth of market etc is wrong or at best out of date now. Perhaps there are ways of viewing “real” depth via Level 2 – Market Makers who own “seats” at NASDAQ are privy to Level 3 and they do see real depth but I don’t think us mortals can. So if anyone can put me right please do so.
By the way, I think I'm right in saying that IB level 2 used to be worse than useless as it didn't incorporate any of the ECN orders, but that may have changed now.
Hope this helps
Cheers
