This calculator comes with ATR calculations based on five different time periods plus a the standard deviation over the past 50 days, and all these measurements are calculated for thousands of stocks and resident within StopsXL when you download the calculator. 

1. It is not necessary to download or enter new data every day.  All the user has to do is enter the most recent high, low, and close for any stock under review.

2. Our premise in creating this calculator is that because the user is given a variety of volatility measurements, including a 7-day ATR, a 14-day ATR, a 21-day ATR, a 100-day ATR, a 200-day ATR, and a 500-day standard deviation of the ATR.  It is not necessary to download new measurements every day.  Whatever the current measurement is, it is likely to be covered by one of the internal measurements. Here is why this can work.  The real danger, in our view, in using a volatility measurement to determine the position of a stop loss occurs when using a measurement that is too small, resulting in an unnecessary and premature sale.  Measurements that are a little large, give the stock a little more “wiggle room.”  StopsXL determines the greatest ATR calculated for all indicated periods for all stocks. Using the greatest ATR for all these periods makes it very unlikely that the current ATR, whatever it is, is greater than the one being used.  When a symbol is entered, StopsXL displays the identity of the ATR with the greatest calculated value for that stock (so the user does not have to search for it). The user can then enter the period for that ATR for that stock, or he can enter the period for any other calculated ATR. The Stop loss will then be calculated relative to the most recent high, low, or close, as entered by the user (the user should enter the latest high, low, and close for the stock of interest in the columns I, J, and K.

3. There are no charges for using StopsXL.

4. User should download a fresh copy of StopsXL weekly (to get fresh data).  

5. StopsXL has a “Multiplier” function that enables the user to “weight” the ATR or standard deviation. For example, the stop loss can be calculated for 1.76ATRs below the close or 3.21 standard deviations below the latest high, etc.

6. StopsXL calculates pivot points, resistance level 1, resistance level 2, support level 1, and support level 2.

7. StopsXL can also calculate Fibonacci retracement levels

Dr. Winton Felt Educational background. Dr. Felt did his graduate level studies in Systems Engineering/Applied Mathematics, English, Management, and Clinical Psychology. During a good portion of the time he was involved in his graduate studies, Dr. Felt also operated his own business, teaching advanced reading and study techniques at four colleges in Southern California, and conducting special classes for various Christian organizations. General history of securities-related experience. Felt began his study of security trading patterns (emphasizing the “point-and-figure” method and outcome probabilities associated with various patterns) when he was in his early 20's. He became a professional in the financial services industry in 1985. He did his basic brokerage training at Merrill Lynch and achieved perfect scores on the “Series 7” in the areas of “Portfolio Analysis” and “Investment Strategies.” At Merrill Lynch he became the “Mutual Fund Coordinator.” A few years later, he was recruited by Bateman Eichler, Hill Richards (Everen Securities) to finish the development of a stock-trading system and to use it in managing a pooled account. He then founded Asset Management Systems and continued his work on the development, analysis, and evaluation of investment disciplines and strategies. He used multivariate analysis to test the profitability of more than 50,000 investment strategies. He then used the results of his analyses to design high total-return strategies. He also wrote algorithms to enable a computer to search through thousands of stocks to identify those that have any of a variety of behavior patterns known as "setups," price and volume configurations that most often occur shortly before a price surge. Dr. Felt created the Market Bias Indicator (MBI), also known as the Felt Oscillator, the Force of Trend (Group Pressure Gradient) indicator, and a procedure for discovering what he calls "Key Intraday Levels." He managed portfolios, created investment disciplines, created the publication originally known as Value Indicator (later renamed The Valuator), created what was originally a 70-page weekly publication known as StockAlerts (our present StockAlerts subscription service is a derivation and subset of this no longer available publication), and was the founder of Stock Disciplines, LLC. Work and licenses before becoming the principal officer of Stock Disciplines, LLC. Dr. Felt has held various licenses as an investment professional. During the years immediately before he became the principal officer of Felt Financial, LLC. (through which he managed investment advisory accounts), Dr. Felt held a “Series 7” General Securities license and was registered with the NASD. He also held a “Series 24” license issued by the NASD. A “Series 7” will qualify a person to be a “Registered Representative” or “Investment Broker,” and is the license held by the more qualified “brokers” at major brokerage houses. This license is a prerequisite to sitting for the “Series 24” exam. The “Series 24” license is required for those who supervise other brokers (securities regulations stipulate that every Broker/Dealer firm must have at least one individual who is licensed as a "General Securities Principal"). Having both a “Series 7” and a “Series 24,” Dr. Felt had the NASD designation “General Securities Principal” (it should be noted that registration and licensing by the State of California, the SEC, or the NASD does not represent a mark of approval or endorsement by these regulatory bodies, but that certain standards of knowledge and other requirements have been satisfied). During this time, Dr. Felt was affiliated with Titan Value Equities Group, Inc. as a Registered Representative, a Registered Principal, an Advisory Associate, and as the manager of an Office of Supervisory Jurisdiction. Felt Financial, LLC. (of which Dr. Felt was the principal officer), remained in the investment advisory business as a Registered Investment Advisor until December 31, 2005. After that date Felt Financial, LLC. became Stock Disciplines, LLC., and the firm (and Dr. Felt) stopped providing investment advisory services (use the link below for more on why the advisory business was abandoned). Dr. Felt has also conducted investment strategy seminars and tutorials for investors and brokers. Past Affiliations.
