In the final part of this series, we will break down all of the functions of our Stock Scanner. We will also show "how's" and "why's" behind these functions and how you can maximize your benefits of this TradingMarkets.com feature. Finally, we'll answer some of the common questions regarding the scanner.

The Date Range

The Stock Scanner allows you to enter a date range for stocks to be scanned.  In most cases, you'll probably want to leave both "start" and "end" date to the last date in the database (the default).  This will allow you to find the latest stocks that meet your criteria.  However, for the more adventurous, you might want to broaden the date range to find stocks that have recently met your criteria.  Further, for research purposes, you might want scan historical dates and then analyze how these stocks have performed since those dates.

The Sub-Sector

If you're just looking for a broad list of stocks, then leave the Sub-Sector set to "All." However, if you are looking for the hottest stocks in a particular sector, then use the pulldown menu (the arrow on the right) to set to whatever sector you might be interested in.

A list of Sub-Sectors is provided below.

Minimum and Maximum Price

This feature allows you to set the price range for the scan.  Some daytraders/short-term traders tend to focus on higher-priced stocks as they generally have the potential to make larger point moves.  Some position traders may consider lower-priced stocks as they have to potential to make larger percentage moves over the long-term.  Don't care about price? Leave it blank.

Minimum/Maximum Volume

Enter the minimum and maximum volume requirements here.  The volume figures are expressed in hundreds so leave off the last two zeros. For instance, in the example below, we are looking for stocks with an average volume of 500,000 (5000*100) or more.  

Many short-term traders tend to  deal with higher volume issues in order to ensure they have the liquidity to move in and out of the stocks.  Other traders may put a maximum volume figure in order to help them find smaller-cap stocks.  

Note: Stock Scanner does not recognize any non-numeric characters. Therefore, do not put commas into any of the fields.

ADX

ADX is a measurement of trend developed by Welles Wilder. Its calculation is based on the up directional movement index (DMI) and down DMI.  The directional movements are calculated on a cumulative basis by comparing what range of today's price falls outside of yesterday's basis.  For details on how to calculate and interpret ADX, refer to the article Capturing Trends Though ADX under the Trader's Lessons section.

For the purposes of Stock Scanner, all you have know is that the higher the ADX, the more the stock has been trending as of late. "High" becomes a relative figure. In general, stocks that are trending tend to have an ADX of 25 or higher. Keep in mind that this number will vary with market conditions. If  you are looking for trending stocks and are getting too many produced by the scan at 25, then bump up the number to narrow the results. If you are interested in only uptrending stocks, then set the DMI direction to UP. Downtrending? Down. Don't care? All.

Price Change

This feature is useful for measuring one-day momentum thrusts based on price action.  In the example below, we set the minimum price change to 2. This will show all stocks that have went up $2 or more based on date of the scan.

% of Average Volume

This is used to find stocks that are trading above (or below) their average volume.  Many view volume as the fuel for a stock's rise (or fall for short sellers).  In the example below, Stock Scanner would produce all stocks that traded at least twice (200%) the average volume on the date of the scan.

Relative Strength

Relative Strength is a ranking of how well the stock has performed over the given period.  For instance, a stock with a RS of 99 has outperformed 99% of all other stocks over that time frame. The widely used RS (i.e., published in newspapers) is based on a 12-month period.  This long-term RS is great at finding stocks in longer-term trends but may not reflect more recent market action. For instance, suppose a stock is up 500% for the year but then begins a sharp drop, say 50%, over the next few months.  This stock will still have "outperformed" most stocks by still being up 250% for the year but will have under-performed most stocks on a shorter time frame.  In order to help compensate for this anomaly of longer term RS, we have also included a three-month and six-month RS.  

For example, the scan below would provide a list of stocks that have outperformed 90% of all other stocks on a three-, six- and 12-month basis.

Closing Price Comparison To Moving Averages

As you know, a moving average is the sum of a stock's closing price divided by the number of days.  Here we provide the ability to select stocks that are above (or below) their 20, 50 and 200-day moving averages. This helps to find stocks that are in short-, intermediate- and long-term trends as measured by their averages. For more on moving averages, see the articles under Trader's Lessons. 

Sort By

Once we get our parameters punched in, we need to decide how we want the results displayed. If you are just looking for a list of stocks, you probably want to have them sorted by the symbol. However, if you are scanning for stocks based on some other criterion, you might want them sorted based on those criteria. For instance, if you  are scanning for high ADX stocks, you probably would want to sort on ADX and chose "Desc" so the highest ADX stocks would be shown first. For high percentage volume scans, you would want to sort by Vol % and so on and so forth.

Start/Clear

Once you get all your fields set to your liking, hit "Start Search" to run the scan.  Want to start over and try another scan? Hit "Clear Fields".

Find My Stock Only

Suppose you are only interested in an individual issue.  Leave all of the above fields blank and simply enter the stock symbol and hit "GO". Don't know the stock symbol or exact name? Enter as much as the stock name as you know and the Stock Scanner will find the closest matches.

The Results

Once you hit start (or go for an individual issue), the Stock Scanner will process for a few seconds up to a minute or so depending on complexity of the scan. It will then produce a list of stocks based on the criteria you selected above.  For your reference we have included many of the above statistics in the results table. These include:  the date, symbol, name, sub sector, price, change in price, 50-day average volume, 3-6-12 month RS, DMI direction (Up or Down), ADX, Greater Than (or less than) 50 day moving average, Closed in Top (T) or Bottom (B) 25% of the daily range.

With the exception of Closed In Top/Bottom range, these statistics are described above.  The Close in T/B 25% of range is useful to the short-term trader who is interested in how well (or poorly) the stock closed on the day of the scan.  For instance, suppose a stock had a high of 104 and a low of 100 giving it a range of 4 points.  If the stock closed at 103 or higher, it would have closed within the top 25% of the range.  If the stock closed at 101 or lower, it would have closed at the bottom 25% of the day's range (25%*4=1, add 1 to the low for bottom 25% or subtract 1 from the high for top 25%).

We also include  "C" and "Z" hot links. Clicking the "C" will bring up a chart of the stock. This chart can be customized for various time frames (intraday, daily, weekly, etc.). Also, several indicators are provided.   Clicking the "Z" will bring up a Zacks Company Profile  which includes a company description, links to related stocks in the industry and an earnings calendar.

Summary

As you can see, the Stock Scanner is a very powerful and flexible tool.  There are no "right" or "wrong" ways to use it.  If you are looking for stocks in strong trends, you might scan for stocks with high three-, six- and 12-month RS readings. If you are looking for stocks up big on big volume, then put in a large price change combined with a large percentage change in volume.  If you are looking for stocks in strong downtrends (to short), use the ADX and down DMI.  These are just a few of the thousands of combinations available. 

Q and A

Below we have provided some recent questions and answers regarding Stock Scanner.

Q: I'd like to look at all stocks in a given sub-sector. Can I do this with Stock Scanner?

A: Absolutely, set the sub-sector to the sector that you are interested in and leave all other fields blank.

Q: Why would one scan for low ADX stocks?

A: Some look for stocks that may be in the early phases of trend, low volatility, basing etc.  For more information here, refer to part 3 of our Stock Scanner series: How Kevin Haggerty Uses Stock Scanner.

Q. Why use ADX when RS is available?

A: Different people measure trend in different ways. Also, RS is a measurement of strength not weakness. Therefore, ADX (with down DMI) would likely be more useful when searching for candidates to sell short. In other words, these stocks would likely be in downtrends versus simply being outperformed by stronger stocks. 

Q: Why use the scanner? Why not just use the indicators on the site?

A: When we created the indicators for the site, we tried to encompass as many traders as possible: breakout traders, momentum traders, short sellers etc.  However, we soon discovered that many had their own personal criteria and desired  "custom" scans.  Therefore, we created the Stock Scanner which allows for virtually unlimited combinations.

Q: Shouldn't the close above/below moving averages always be the same (i.e., up for longs, down for shorts)?

A: Not necessarily, you could search for stocks in pullbacks by requiring them to be above the 50- and 200-day moving averages but below the 20-day moving averages.

Q: I typed in 500,000 for minimum average volume and get an error.

A: Do not use commas in any of the fields. Also, volume is measured in hundreds. Therefore, in your example, you would leave off the last two zeros and the comma. In other words, for 500,000 shares average volume, enter 5000 (which equates to 5000*100) in the minimum volume field.

Q: I'm just getting started, can you give me some example scans?

A: Sure, kick on "Demo Scans" on the Stock Scanner page. Then, click "Start Search".  Also, read the other three parts of this series for scans from myself and Kevin Haggerty under Trader's Lessons.

Q: What's the best scan?

A: It all depends on your trading style. If you are a momentum trader, you might want to scan for only those stocks that show high RS for three-, six- and 12-month periods or high ADX/DMI UP stocks.  If you are looking for stocks to short, you might want to try high ADX/DMI Down.  If you are looking for pullbacks, you might look for strong stocks as measured by ADX or RS and are also trading below their 20-day moving average.  Also, Kevin Haggerty has shown that you can also find opportunities in stocks that are showing low trend characteristics (i.e., low ADX).

Therefore, the best scan for me might not be the best scan for you.  Start with the scans we have provided, then  EXPERIMENT to find what works best for you.

Q: Is Dave Landry the man?

A: Definitely.
