If you learn how to read into Level 2 on the OTCBB & PINK SHEETS it will really enhance your trading. Let's break down the Market Markets.
There are 4 categories of Market Makers let's start by talking about the first one.
Retail Market Makers:
These are the market makers from very popular brokerage firms. They handle a lot of the order flow for small retail investors.
NITE: NITE
UBSS: Schwab
SBSH: Citibank
ETRD: ETRADE
BOFA: Bank of America
Second Category: This is the list that you really have to master because these are the MARKET MAKERS that can kill a stock in a hurry when they are the sitting on right side of the box on Level 2.
HDSN: killed CKYS single-handedly
VFIN:
CGFL: new kid on the block for sub dilution
RBCM: Old CLYP. Has killed many sub penny stocks in the past to no-bid.
FANC: used to be a heavy S-8 seller. May show up once in a great while.
SSGI: aggressive on sub penny stocks
Third category: There are lot market makers in this category so I will break it down to who are the most important: These are some of the more friendlier market makers on the street.
DOMS: one of my favorites MAXM: VERT: HILL: SALI: can be a seller at times JEFF: FRAN: very friendly ABLE: QUIN: haven't seen him around much lately VNDM: SEAB: MURF: getting active lately STGI: getting active lately VERT: WDCO: can be a seller at times PERT: NIII: BEST: GNLN: nice to see him back again EFGI: can be a seller at times
Category 4: ECN MARKET MAKERS: Electronic Routes these market makers are only used on OTC BB stocks. They do not work for pink sheet market.
ARCA: used a lot by promoters to sell stock TRAC: rarely used any more taken over by EDGX EDGX: new kid on the block
There are probably a few market makers that I left out or there will a few new market makers that show but for the most part these are the major players. Good luck hopes this helps.
