# SharpCharts Indicators and Overlays Parameter Reference

There are several technical indicators and overlays that you can add to your SharpChart. Most of these indicators and overlays can be customized by adding or changing their parameters in the SharpCharts Workbench. The following reference guide shows the required and optional parameters that are available for each indicator and overlay, along with the order they should be entered in the Parameters box.

## Overlays

Technical overlays are lines that are calculated from price and volume data and displayed on top of the main symbol's price bars. To add Overlays to your chart, select the desired overlay from the dropdown menus in the Overlays section of the SharpCharts Workbench, and modify the parameters for that overlay as needed. For more information on adding and configuring overlays, please see the SharpCharts documentation in the Support Center.

Below you will find detailed information about the parameters that are available for each overlay, as well as example charts.

**Parameters:**

**Periods.**Number of periods used in the calculation of the exponential moving average. To change the color of the line, follow the number with a colon and the color (e.g. “50:red” or “100:green”).**Exp (optional).**Price values to be used in the moving average calculation. If the moving average is overlaying a price indicator, then this parameter can be set to O, H, L, or C to calculate the overlay using open, high, low, or closing price values. If this parameter is left blank, closing values are used. The parameter is ignored when overlaying a non-price indicator.**Offset (optional).**Number of bars to shift the overlay to the left or right. A value of zero means no shifting of the overlay; negative numbers shift the overlay to the left/past; positive numbers shift the overlay to the right/future.

**Note:** the two optional parameters can appear in either order.

**Default Parameter Values:**

20

### SMA Envelopes

**Parameters:**

**Periods.**Number of periods used in the calculation of the simple moving average centerline.**Percentage.**Percentage offset of the bands from the centerline.**Offset (optional).**Number of bars to shift the overlay to the left or right.

### ZigZag

**Parameters:**

**Sensitivity.**The value movement threshold of the ZigZag overlay. If set to 5, all value movements of less than 5% will be filtered out. If left blank, a suitable value movement threshold will be determined and used for the chart.

**Default Parameter Values:**

(none entered by default, but when the parameters box is left empty, a suitable value movement threshold will be automatically determined)

**Example Charts:**

### ZigZag (Retrace)

**Parameters:**
