There appears to be a bug in the way your script decides what color to make a stock in the assets list. MergedMining shares are currently showing up as red, which seems to indicate they have dropped in value. However, looking at the list of share sales, you can see that shares are currently at a monthly high. So it should be green, right?

I'll investigate this, the way it currently works is the color depends on the price of the last trade compared to the one before it.
So for example, if the latest trade was for more than the one before it then it's green.
That doesn't appear to be working correctly. Not a big deal, just reporting a bug. Also, a more traditional approach would be using the prior day's closing price instead of the last trade. Great work on 2.0 so far.
