How to add overlays on TA indicators
This Guide demonstrates how to apply overlays to TA indicators in Cryptowatch Desktop.
Technical overlays (eg. Moving Averages, Bollinger Bands) can be applied to indicators and the price chart in Cryptowatch Desktop.
An overlay requires a data source to fill in the equation. Most overlays you would apply to a price chart use the candlestick data as their source.
On Cryptowatch Desktop you can apply overlays to the price chart or to other indicators, such as the Volume or RSI (Relative Strength Index) indicators. The indicator becomes the data source for the overlay.

Example: Adding an SMA to the Volume indicator

On Cryptowatch’s web application, the volume indicator includes an SMA (Simple Moving Average) line by default, but on Desktop it does not.
This section will demonstrate how to add an SMA line to the Volume indicator on Cryptowatch Desktop.
1. Add a volume indicator to your chart via the TA menu. A new “Volume” field appears under “Candle” in the TA menu.
2. Click the + icon to add an overlay, opening the drop-down menu. Select SMA.
3. A new SMA line is overlaid on the Volume indicator.
The “Source” area below any field will describe the overlay’s data source — if another source is available you can select it here.
You can adjust the SMA line’s visual style, or adjust the amount of inputs from the TA menu.
You can also continue to add overlays to that SMA: an overlay on an overlay on an indicator — wild. Just follow the steps above, making sure to apply the overlay to the next, lower field.
