The website www.chartmill.com is a Technical Analysis website created by traders for traders. Its main features are charting applications, a stock screener and a sector analysis tool. Chartmill supports most of the classical technical analysis indicators along with some state-of –the–art indicators and concepts like Pocket Pivots, Effective Volume, Relative Strength and Anchored VWAPs (MIDAS curves).
First, we’ll discuss some of these concepts. After that, we’ll have a look at the screener and charting applications.
Relative Strength is available in different forms at chartmill.com. Two relative strength related indicators are available in the charts and screener:
Besides these two indicators, there is also the Relative Strength Ranking Number. Here, each stock gets assigned a number between 0 and 100, indicating the percentage of stocks that is outperformed by this stock. For example: a stock with a Relative Strength Ranking number of 92 outperformed 92% of all stocks in the last year.
This latter form is highly usefull in the screener where one can filter stocks based on their ranking number.
The screener supports the concept of ‘strong stocks’, which are stocks with a high relative strength. But there’s more. Not all stocks with a high relative strength ranking are also ‘strong stocks’. Relative strength looks at the performance over the past year. Some stocks just made a huge jump at some point because of a fundamental event. This jump gives them a high relative strength value. However, one is not interested in those stocks, but in stocks that show a nice and steady trend over the year, not stocks that are flat, jump 300% higher and then flatten out again. Strong Stocks filters the nicest steady trends in the market and does a terrific job in mimicking IBD stock lists.
Effective Volume is an indicator that was introduced in the book ‘Value In Time’ by Pascal Willain. The indicator looks at the intraday minute data to find out what large players are doing in a certain stock. It is able to discover accumulation or distribution by large players in the analyzed stock.
Effective Volume is used in several ways on chartmill.com:
More not so common indicators
The charts and screener support some other indicators that are not commonly found in other charting applications:
The most impressive feature of www.chartmill.com is definitely the stock screener. The concepts listed above are all supported by the screener. Figure 1 shows a screenshot of the screener.
The screener has a number of tabs ( marked ‘A’ in screenshot ) that group a set of settings ( ‘B’ in the screenshot). There is:
Below the filters, you can select how you want to see your results. (‘C’ in the screenshot ).
All views of the screener will present overlay charts of the results so that you can immediately inspect lots of them. You can fully configure the charts that will be shown in the overlay with the chart settings ( ‘D’ in the screenshot). You can even include indicators.
The chartmill.com homepage offers an easy entry to the screener and contains some handy shortcuts to get started. Traders can start from the shortcut and can then further refine the filters based on their needs. Figure 2 shows these shortcuts.
Chartmill.com has 2 charting modules: the Basic Charts and the Advanced Charts. Both allow charts in different formats and timeframes with technical indicators and user annotation.
A nice feature of both basic and advanced charts is that you can view multiple charts at a time. If you enter a comma separated list of tickers, all your charts will be shown.
The Advanced charts are more interactive. The advanced charts allow right-clicking on the chart to add anchored indicators on a certain candle. Examples of anchored indicators are stops or vwap’s and will be explained in a minute. Another nice feature of the advanced charts is the position sizing tool, which will also be explained next.
Position Sizing Tool
As every trader should know, the most important aspect of trading is position sizing: you determine where you get out if the trade fails and based on your entry and exit you can determine how many shares you can buy given your account size and the risk you allow for this trade. The position sizing tool does these calculations for you.
The picture above shows the position sizing tool. It shows a trade on AMZN. The desired entry and exit are filled in, which can be done by right-clicking a chart at the desired entry en exit level. The tool requires the available capital and the % risk one wants to take for the trade. With these numbers filled in, the results are shown in the tool.
In the example, the tool calculates that 72 shares can be bought. If the trades is stopped out, the trader will lose 1,5% of his account or 748.48 dollar. Note that the tool also warns that the total investment is rather big ( over 25% of total port size ) and that the stop is positioned at less than 1 ATR from the entry price, which is too close.
Anchored VWAPS and Stops
An input to for instance an ATR-stop on a chart is the day of the entry. The stop should calculate the maximum price from that day onwards and should subtract n times the ATR value from that. The starting point is called the ‘anchor point’.
Anchored VWAPS and Stops are supported by both charting applications, but the advanced charts allow you to interactively select the candle where the VWAP or Stop should be anchored, i.e. calculated from.
The site also has a sector analysis tool which allows sorting sectors and industries based on their recent performance, the average accumulation or distribution, the number of new highs, the amount of pocket pivots or many more sector properties.
When a certain sector is found interesting, clicking it opens the screener with the individual stocks from the selected sector.
Finally, chartmill.com also listens to traders and its homepage contains a feedback form. All feedback and suggestions are welcome and are taken into account.
