On the Market Scoring Report, you can check the market indicators of your chosen market showing the trends from weak to strong or vice versa.
You can also get ‘Details’ by clicking on right side of the indicator and you can also view the Charts.
The chart you see with buy and sell signals is actually a chart for annual APPRECIATION RATE (not a chart of real estate VALUES).
So, any time the blue line is above the ‘zero’ line means values are increasing. Anytime the blue line is below the zero line, values are declining.
For example, if the blue line was perfectly horizontal at the 5% positive appreciation (and parallel with the zero line) then EACH YEAR values increased 5% over the preceding year.
