Performance Indicator

The Performance indicator displays a security's price performance as a percentage. This is sometimes called a "normalized" chart.
The Performance indicator calculates the percent that prices have changed since the first day loaded in the chart. Therefore, if you want to calculate a security's performance from a specific date (e.g., the day you bought it), you should first use the X-Axis Properties dialog to change the first date loaded.
Interpretation
The numeric value of the Performance indicator is the percentage that the security has changed since the first period loaded. For example, a value of 10 would mean that the security's price has increased 10% since the first period loaded on the left side of the chart. Similarly, a value of -10% would mean that the security's price has fallen by 10% since the first period.
Calculation
Performance = 100 x (( price(0) - pricestart ) / pricestart )
