1.)  If a historical chart has exceptionally high volume compared to recent volume, the volume grid on the bottom portion of the chart isn't adjusting to show the true volume.  See attached chart for symbol ISR.  Volume on 3/19/2014 is over 87 Million, and on 3/20/2014 is over 112 Million.....however the chart is only displaying about 35 Million for both days.  If you scroll the chart back to 7/12/2011, it also doesn't show the higher volume of over 2 Million.  Scrolling back to 1/21/2010 the volume is over 10 Million, but the chart only displays a bit over 3 million.

2.) If you have charts linked to a portfolio (using the Symbol Link Group colors), and delete a symbol from that portfolio, the row on the portfolio below the symbol that was just deleted is now highlighted (as expected), however the symbol that was just deleted is still showing on the charts, not the one that is now highlighted on the portfolio.  It's a bit confusing and might cause a user to make a trade on the wrong stock.  I know that you can click on that highlighted row in the portfolio and the linked charts will get updated, but it would be nice if it just displayed the chart data as soon as the old symbol is deleted (like it does in QT).

Volume: I didn't want to adjust to the highest volume on the chart always, because sometimes that volume is hugely higher than all others (as in your example) and the chart of volumes becomes worthless - basically a flat line with one bar sticking out.  The way the Y axis is adjusted right now is, it takes the minimum of:

 

Average volume for the visible part times 10

Max volume for the visible part time

 

and uses it as the max Y for the chart.  If you can think of a better method to do this, please feel free to suggest it.

For issue 1, a huge volume spike sometimes presents trading opportunities for days to come and such historical spikes indicate that similar future extreme volume spikes can occur.  Perhaps an option to show it with the current methodology or with "true volume" would work?  The problem locking it into a formula is that you can't see how extreme the volume move is such as the QT chart shows below: (User preferences will probably vary)

For Issue 2, whatever you can do would be great.....just trying to avoid extra mouse clicks and trading errors.

 

Thanks,

Tim
