Hi Jim,
For the graph: "Graphs / Cost - Price" there is a "Price" line and a "Cost" line. Each are controlled by these colors:
Price: NAV lines/Upper TA 1
Cost: NAV overlaid/MA 1/Upper TA 2
Admittedly, these names are confusing, but let me try to explain. The same colors are re-used in the NAV based graphs as well as the Technical Analysis (TA) graphs, so when in an NAV based graph, these 2 choices are:
NAV lines
NAV overlaid 1
Where the price is the "line", and the cost is the first overlay. The label:
NAV overlaid/MA 1/Upper TA 2
is trying to say that in the NAV based graphs it is the first overlaid line, and also the first moving average (MA) in the NAV based moving average graphs (Graphs / Moving Average / Share Price). In the Technical Analysis graph it is the second color for the upper section. The first color being the closing price, and the second color being the first SMA. These are documented in the
TA graph help.
