I was looking to get the opinion of anyone here who looks at stock charts and uses a narrow-width device (iPhone, etc - basically, anything less than 500px or so). I was wondering: 1. if you look at charts on your narrow device or simply wait to do it on a more usable device like a laptop/desktop. 2. if you do view them on a narrow device, how do you do it? do you zoom in and then scroll the chart across, or some other way? 3. is there anything a web site could do to make trading charts more compatible/usable on a narrow-width device?
If you get the URL of the chart from stockcharts.com, you can open it directly, scroll and zoom or do whatever. I wrote a script a while ago that allows me to extract a preset chart choice (Normally it will reset to the default chart after some time), and then display it as 100% height and width. First load the stockcharts page for that symbol: 1) http://stockcharts.com/h-sc/ui?s=AAPL 2) Set up the chart the way you want it. 4) Copy the url of the chart by right clicking on it: Code: http://stockcharts.com/c-sc/sc?s=AAPL&p=D&b=5&g=0&i=0&r=1435821645687 3) Write a script to extract the chartID (r=) from the original page source: Code: <img id="chartImg" src="/c-sc/sc?s=AAPL&p=D&b=5&g=0&i=0&r=1435821645687" /> 4) Use the r= variable to modify your image URL from (4) 5) Display the image as a fullscreen chart. Notes: The r= variable changes once every hour or so. I just load the page from the script and extract it. You can use the "Linkable version" on stockcharts.com to load the setup page you like from a script. Edit: I missed the part where this was a survey. If you work for Stockcharts.com, please allow fullscreen charts, so I don't have to load the chart page twice to extract the information.
I usually simply control the whole process when I am on mobile and nothing really more than this and that's it. For sure some serious trading I do only on desktop with ethernet internet access with 1GBPS and few monitors, that's for me.
