Level II part 1 < TheSlayer > on my system, the different levels of bids and asks are color coded < TheSlayer > each level a different color < TheSlayer > I think yellow is one of them < TheSlayer > but what they mean - that has to be obvious < TheSlayer > those numbers on the L2? They usually mean the size of the bid and ask < TheSlayer > some people actually don't know that < TheSlayer > actually, I am looking at my L2 < TheSlayer > I will describe what I see < TheSlayer > anyone interested can follow me < TheSlayer > others can just listen to my singing < TheSlayer > lol < TheSlayer > You should have your L2 set in the classic style < TheSlayer > that is, basically the bids on the left and the asks on the right < TheSlayer > NOT the bids on top and the asks on the bottom < TheSlayer > I can't believe some people actually do it that way < TheSlayer > anyway, so they should be next to each other < TheSlayer > basically, two columns of information < TheSlayer > let's look at the left column < TheSlayer > the bids < TheSlayer > the bid side is made up of individual columns < TheSlayer > on mine, there are five columns of information included on the bids side < TheSlayer > I'll go through each column and what it means < TheSlayer > looking out the window to the extreme left < TheSlayer > we have the limit column < TheSlayer > you will notice lots of L's in that column < TheSlayer > in fact, right now they are ALL L's < TheSlayer > because only limit orders are in place < TheSlayer > there being no market orders active on Friday night < TheSlayer > the L indicates, as you would gather, that it is a Limit order at that price] < TheSlayer > so, when you enter a limit order with your broker < TheSlayer > guess what he and every other broker and mm sees? < TheSlayer > YOUR LIMIT ORDER! < TheSlayer > L's < TheSlayer > as in letter L < TheSlayer > lot of them < TheSlayer > lots of them < TheSlayer > ok, so the L's are the extreme left column < TheSlayer > now, the next column is the price column < TheSlayer > oops, no < TheSlayer > I take that back < TheSlayer > the next column is the mm column < TheSlayer > this shows who is handling the bid or ask < TheSlayer > They have funny names like MASH, SLKC, and NITE < TheSlayer > NITE is easy - but a box of cyber candy to anyone who knows aht SHWD stands for < TheSlayer > or MWSE < TheSlayer > or ALWC < TheSlayer > or VOLP < TheSlayer > or DLCR < TheSlayer > or ... well, you get the idea < TheSlayer > ther are lots of these guys < TheSlayer > and most knowledgeable daytraders don't have a clue what they stand for < TheSlayer > but if you know who the initials stand for < TheSlayer > it can help you < TheSlayer > for example, < TheSlayer > GSCO - I bet someone here knows who that stands for < TheSlayer > ? < webmaster > Goldman < garz > goldman sacks < TheSlayer > BRAVO < TheSlayer > people see GSCO on the bid < TheSlayer > and they go, wait < TheSlayer > those guys are GOOD < TheSlayer > they must KNOW < TheSlayer > something I don' < TheSlayer > t < TheSlayer > so when you see GSCO sitting on the bid < TheSlayer > which means always seeming to be the one at the top of the left column < TheSlayer > which means they are buying like crazy < TheSlayer > that is a REAL GOOD CLUE that they are buying big time < TheSlayer > for somebody < TheSlayer > such as themselves < TheSlayer > who has access to information < TheSlayer > you may not < TheSlayer > so pay attention < TheSlayer > to the mm column < TheSlayer > even if you don't know all the abbreviations < TheSlayer > 'cuz some matter < TheSlayer > and some don't < TheSlayer > like ISLD < TheSlayer > lol < TheSlayer > j/k < TheSlayer > ISLD - who knows the significance of ISLD? < TheSlayer > who is ISLD? < TheSlayer > YAY < webmaster > Datek < TheSlayer > that's right - ISLD is daytraders like you and me < Charlie_D^ > DATEK < TheSlayer > working on the ISLAND ECN < TheSlayer > so ISLD shows what the daytraders are doing < TheSlayer > at least, the not-so-clevers ones who are forcing your stock down < TheSlayer > ;) < TheSlayer > I hate ISLD < TheSlayer > anyways.... < TheSlayer > pay attention to the mm column < TheSlayer > now, the next column is the price column < TheSlayer > that should be the fattest column < TheSlayer > the one with all the colors < TheSlayer > mine is fairly typical < TheSlayer > I think < TheSlayer > the top layer is yellow < TheSlayer > the next is green < TheSlayer > the next is blue < TheSlayer > and the bottom is red < TheSlayer > each layer contains bids of the same price < TheSlayer > from different mm's < TheSlayer > assuming there is more than one mm at a given price < TheSlayer > the different colors < TheSlayer > tell you at a glance < TheSlayer > how far away from the actual bid the price is < TheSlayer > that you are looking at < TheSlayer > so, say the actual bid is 113 1/8 < TheSlayer > which is what VERT shows right this second < TheSlayer > on L2 < TheSlayer > (though that is not the REAL bid, cuz there are no market orders around) < garz > hence the colors assist in quick decode'n < TheSlayer > now, all bids at 113 1/8 are in yellow < TheSlayer > right now, that august group consists of one mm < TheSlayer > or one bid < TheSlayer > SLKC < TheSlayer > below it < TheSlayer > at 113 < TheSlayer > is another bid < TheSlayer > this one in green < TheSlayer > this is from MASH < TheSlayer > we are looking at VERT pay ATTENTION < TheSlayer > again, there is only one bid at 113 < who2 > We are looking at a course on L2 < TheSlayer > which is not unusal after hours < TheSlayer > so we have established that there is one bid at 113 1/8 < TheSlayer > and another at 113 < TheSlayer > and they are distinguishable in two ways < TheSlayer > one, they are color coded differently < TheSlayer > and two, they are different numbers! < TheSlayer > lol < TheSlayer > but the colors is the key < TheSlayer > 'cuz at a glance, as garz so wisely said < TheSlayer > the colors tell you they are different values < TheSlayer > now below the green layer < TheSlayer > is the blue layer < TheSlayer > and that contains another different number < TheSlayer > this time a slightly lower bid < TheSlayer > 112 3/8 < TheSlayer > and below that, the red layer < TheSlayer > with another different bid < TheSlayer > again lower < TheSlayer > 112 1/4 < TheSlayer > you'll notice the bids go down the further from the top you get < TheSlayer > it should be obvious why this is < TheSlayer > bids are the highest someone will pay for a stock < Thuan > They exist so you can easily tell the difference in price levels. Yellow represents the market makers with the best bid and ask prices, green the next best, etc. < TheSlayer > and the people who pay the most are at the top < TheSlayer > because those are the people the sellers want to deal with first < TheSlayer > the lower bids - sellers don't want those at all < TheSlayer > until the highest bids have been satisfied < TheSlayer > and thus disappeared < TheSlayer > so, natually, the number of bids in each level is significant < TheSlayer > should the price hit that level < TheSlayer > but the thing about L2 is < TheSlayer > you don't see all the bids below the toppermost layer < TheSlayer > ah ha~ < TheSlayer > this is something a lot of people don't get about L2 < TheSlayer > you don't see all the bids < TheSlayer > you only see all the bids at the highest level < TheSlayer > you don't see lower bids < TheSlayer > made by the same mm < TheSlayer > so in our example < TheSlayer > SLKC has the highest bid < TheSlayer > at 113 1/8 < TheSlayer > but he could ALSO be willing to bid < TheSlayer > 1000000000000000 shares at 113 < TheSlayer > and you would never know it on L2 < TheSlayer > until the 113 1/8 bid is eaten up < TheSlayer > on L3, you get to see the whole panorama < TheSlayer > all bids by all mm's at all prices < TheSlayer > but we don't use that < TheSlayer > only L2 < TheSlayer > so L2 is misleading < TheSlayer > though it does give you a clearer picture < TheSlayer > than just about anything else < TheSlayer > L3 I think is only available to brokers < TheSlayer > not sure about that < TheSlayer > but I think so < TheSlayer > but L2 is really good enough < TheSlayer > because, once you are familiar with it < TheSlayer > you can get a good idea of what other bids < TheSlayer > the guys at the top are making < TheSlayer > by shrewd deduction < TheSlayer > and, anyway, they'll pop up eventually anyway < garz > the number listed by mm is required to trade but not limited < TheSlayer > that's right garz < TheSlayer > the mm has to bid at least that number of shares < TheSlayer > if asked < TheSlayer > but he can throw more shares out < TheSlayer > as long as he wants < TheSlayer > again, this is called < TheSlayer > sitting on the bid < TheSlayer > accumulating shares < TheSlayer > being a share hog < TheSlayer > and the like < TheSlayer > ok < TheSlayer > I think you get the picture on that column < TheSlayer > on some L2 < TheSlayer > they indicate whether that mm < TheSlayer > has raised or lowered their bid < TheSlayer > from their last offer < TheSlayer > thus, the little symbols next to the numbers in that column < TheSlayer > in my L2, they are + and - < TheSlayer > in yours, they may be different < TheSlayer > but + and - makes the most sense to me, personally
