Hi Mark,
Quite often, there are some wrong OHLC data in the prices. They warp the graph.
Here for example, a wrong high value: https://img15.hostingpics.net/pics/6923 ... 2h2801.png
In order to fix these quickly, a command to edit the price right under the cursor would be nice (or the existing Update price command set with the date/price right under the cursor).
