Quote from lynx2004:
Through what do you see all this to try to decode MM action in the EUR futures...? I trade through IB TWS and all I can see is the mkt depth window...couldn't tell MM or not except to guess by size...some insight would be appreciated..
The MM frequently has some big size bid, ask orders which it moves out of harms way most of the time. Many times they also deploy various "techniques" - like flashing, rapid toggling, trapping with smaller lots etc.
While you can clearly see some retail customers - usually minor lots - and most often 1-lots - being traded - the bigger lots frequently seem to be eaten by the MM. You can see big volume being withdrawn from price-levels, and some minor volumes staying when spot prices fluctuates. Some times this seems to be part of the MM strategy, and other times this might be retail customers.
Some other big customers or market maker salso meddles in - and this becomes evident with varying flashing and reaction times to spot price variation etc. Many times it seems the MM cap markets either way to their advantage - or even trigger opposite reaction moves on some specific trades and price levels being hit. Other times the fun game of "slapping" seems to happen when they fight it out with 1-lots both ways to print the tape. Other times they spoof volume rapidly - probably some built-in FUD-technique (Fear, Uncertainty, Doubt).
If I had access to Globex User IDs I would try and get an edge in knowing their tricks and better understanding how they pressure market participants - "make markets".
The most common technique seems to be big spreads and unfavourable small lots held on price levels as to not having the future getting printed on the equivalent spot price - when it's unfavourable to their holdings not squared off. You can e.g see a 200+ lot on best ask sometimes, while the other 200+ lot is 2-3 ticks lower than the best bid - with 2-3 small lots holding up the space between. Sometimes this can be smaller retail customers - but in the wee hours it seems to be a strategy deployed in thin markets.
I spend almost all my time when trading analysing the play in the orderbook, and I find it similar to guessing moves in e.g Shogi-games (japanese chess). If I had user-id's linked to the order-book and T&S info I would have had a full confirmation of the patterns I see.
My opinion is that it would be very, very, very worthwhile to analyse these trading patterns by the Market Maker during hours where they manipulate greatly - to be able and extract some edge over the market maker. That would be equal to having an edge over the casino house - in those specific conditions. The condition would not be present during normal RTH - most times , except in some choppy ranges - nor when some underlying bigger spot moves were taking place.
As the market maker is the one taking opposite side of your trade at these times, they would surely not have in their best interest to let you gain on your trading - so they have a bag of tricks to "scare you" from holding your position - or trade the market in the opposite direction when their holding allows for them to do so. That's how they are making money. They're seemingly not making money on "making bets" - they take bets from traders and do their best, which obviously involves a lot of processing about how traders are trading.
Some trades you can recognize by trade size - but other trades you can get by "trading patterns" - i.e indicators etc. If you also have the User ID to uniquely identify the trader - you have a tremendous edge. That edge can be approximated by analysing the book, but it is obviously very hard - NPC - knapsack-related problem.
When you frequently see your stop being hit and then the market reverses you know that they have an edge over you. Identifying "small patterns" and pieceing together movement indications can some day give you an edge. Otherwise the RTH are probably the only safe hours to trade unless there are a lot of overnight spot activity, or you employ very wide stops.
Applying the old voodoo-doll technique might be just as effective at times.
Scalping in illiquid market conditions with market makers with a great edge over you is probably some of the more difficult trading you can do - unless you are using a similar edge. They can widen spreads, flash big volume to lean on direction and fill up spreads away from the underlying market price. So it's not a cakewalk. Doing some positions can be good though, although there are issues when markets get shrugged by choppy trading and frequent range-changes, or stair-stepping.
If you had a choice, you would probably prefer to hit other traders' orders than the market maker's to try and avoid the MM skewing his market against you.
