Calculations of Volume
Many people mistake while calculating volume in trading, check illustration given below, to understand it in details.
Volume is a very important data and we can get following details from it. Volume analysis is used to confirm the strength of a buy or sell signal.
1. Low Volume: Low volume means there are less number of stocks traded in exchange. We should stay away from such stocks as there is a liquidity risk involved. Also such stocks do not have a good reputation hence less number of people shows interest in it.
2. High Volume: Generally good stocks have high volume, which reduces liquidity risk. More people are trading these stocks indicate more people want them in their portfolio. Trading volume is usually higher when the price of a security is changing. News about a company's financial status, products, or plans, whether positive or negative, will usually result in a temporary increase in the trade volume of its stock.
3. Change in volume: One of the important indicators is change in volume. If volume is increasing and price is also increasing, this is a strong buy signal. If price is decreasing and volume is increasing, interpret as sell signal & Sell your stock.
4. False Breakout: On the initial breakout from a range or other chart pattern breakout, a rise in volume indicates strength in the move. Little change in volume or declining volume on a breakout indicates lack of interest and a higher probability for a false breakout.
Buyers and sellers help determine the price of each stock, and the more buyers and sellers a particular stock has interested in it, the more liquid the market will be. Liquidity can have a profound impact on just how violently stock prices can move in either direction, and the reasons have to do with the nature of the market in a stock's shares. Higher volume for a stock is an indicator of higher liquidity in the market and shows more interest of buyers and sellers. Highly liquid shares have lower impact cost as reflected in tightness of their bid-ask spread.
Volume and Chart pattern
Volume is invaluable when confirming chart patterns, such as head and shoulders, triangles, flags, and other patterns. If volume isn’t present alongside these chart patterns, then the resulting trading signal isn’t as reliable. False breakout of pattern is witnessed in absent of volume while pattern completion.
Volume is important to consider in bullish breakouts; however one should not give more importance to volume in bearish price patterns, which pushes prices lower.
Volume and Market Interest
A rising market should see rising volume. Buyers require increasing numbers and increasing enthusiasm in order to keep pushing prices higher. When prices rise or fall, an increase in volume acts as confirmation whether the rise or fall in price is real and that the price movement had strength.
Volume and exhaustion Moves
In a rising or falling market, we can see exhaustion moves. These are generally sharp moves in price combined with a sharp increase in volume, which signal the potential end of a trend. Participants who waited and are afraid of missing more of the move pile in at market tops, exhausting the number of buyers for further period. Increasing price and decreasing volume show lack of interest and this is a warning of a potential reversal.
