Signal transformations

Once you have a signal, you can apply transformations to the signal or combine it with other
signals. This section describes how this is done.

• Arithmetics
• Modifications
• Change transforms
• Resampling and aggregations
• Rolling aggregations
• Extract data
• Statistics
• Combining signals
• Signal template
• Cross-sectional aggregation
• Companies, entities and tags
• Advanced signal transformations
• Pandas operations
• Point-in-time
