Use a Volume Indicator for Stock Picks
In the early days of Technical Analysis all of the data from the Stock Market was not readily available, in a format that could be hand-drawn on a chart. The earliest chartists had to create their charts using either Point and Figure, Line, or Bar Charts. Candlesticks were not introduced to the western markets until the 1990’s.
Data that was used on the earliest charts was primarily Price and Time. Quantity aka Volume was seldom included and it was fine to focus solely on Price, because there were only a few exchanges and it was only rarely that off-exchange orders were filled. Nowadays there are some 70+ Alternative Trading Systems and Exchange venues.
Since the bulk of orders now filled off-exchange are in Dark Pool venues, Volume has become a critical indicator in order to fully understand the dynamics of Price.
Adding Volume and Volume leading indicators provide the missing data which is crucial in the automated marketplace needed for using a Complete Data Set for Stock Pick Analysis.
High Frequency Trading Firms are here to stay and are now an integral part of the “market making” computing community.
Market Makers or Maker-Takers receive a rebate from the exchanges for providing liquidity. High Frequency Trading Firms have become a major contributor to maintaining the liquidity of exchange activity against the Dark Pool venues, which have controlled the bulk of orders for several years.
Dark Pools are often delayed orders during the day, OR the large lot orders will fill before the market opens. Using a Complete Data Set for Stock Pick Analysis includes using all data gathered after the market closes from every venue, since the Consolidated Data differs considerably from End-of-Day EOD exchange Close Data which is the closing data of the day.
Volume Bars provide considerable information beyond the “green is an up day, and red is a down day” in the basic courses for beginners. The length of the Volume Bar matters. Using a Moving Average or other subordinate indicator can help determine the average of Volume, which provides an easy visual reference.
NEVER truncate your Volume indicator. This is a mistake because the bars represent the total number of shares traded that day, and will provide many “indications” required to understand who controls Price on that day.
Chart example #1 below has Volume to the upside that is above average, during the final low and bottoming phase of this Downtrend.
The next day the stock moves with a huge point gain, a nice entry was set up the day before and since the stock ran rather than gapping, this was a good easy Swing Trade.
The Volume Bars clearly indicated the bottom had accumulation intermittently, and the compression of Price also indicates a potential for a High Frequency Trading run. See chart example #2 below.
