If you’ve ever remodeled a home, you understand how even the smallest change can sometimes spiral into something much larger. One fixture you love clashes with something else, so you create a short shopping list. When you start pulling things out you realize that you should probably replace the wiring and plumbing. If you’re going that far, you might as well remodel the entire room. And before you know it you have a new kitchen.
Upgrades can be unpredictable like that.
I recently had a similar experience working on some new tools at Portfolio Charts. It began with redesigning the Toolkit to add some new charts and make it much simpler to enter data without so many steps. The result was so useful that I realized I could apply it to the site infrastructure to make my job way easier. If I was going that far, I might as well make some interface changes that I’ve been thinking about for a while now. And before I knew it I updated nearly every page on the site.
If you only have a few minutes, here are the major changes to be aware of:
- All of the backtesting tools have a new interface with a more intuitive layout and built-in ETF-finding capabilities.
- Some data has been tweaked, like the shift from total stock market to large cap blend funds in portfolio definitions and the elimination of expense ratios. So the resulting numbers may be slightly different than before.
- Old bookmark links will no longer work, so you’ll need to save them again.
- The Toolkit is massively easier to use. If you ever downloaded a free sample, you may receive an email with a new one to tinker with. And Toolkit owners should be on the lookout for an email with a free update.
If that sounds interesting, the full upgrade list is pretty extensive. Read on to learn more.
