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.

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 our 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.

Adds a horizontal line to the indicator panel at the specified y-axis level. A horizontal line can be useful when you are watching for indicator values to cross above or below a certain level.

**Parameters:**

- yAxisLevel - The level on the y-axis where you want the horizontal line to appear on your indicator panel. Multiple horizontal lines can be added by separating multiple Y-axis values with commas (e.g. “50,100,150,200” would display four horizontal lines). To change the color of a specific line, follow the number with a colon and the color (e.g. “50:red,100:green”).

**Example Charts:**

Adds a simple moving average overlay to the indicator panel. The moving average is calculated using the values of the indicator being overlaid.

**Parameters:**

- Periods - Number of periods used in the calculation of the simple 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.

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

**Default Parameter Values:**

**Parameters:**

- Periods - Number of periods used in the calculation of the upper and lower channel lines.
- 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.

**Default Parameter Values:**

- 20
