You'll find an answer in the QuickRef, it's very simple:

What does >> do to a DataSeries?

Warning: shifting data to the left (from the future to the past) using the << operator is peeking into the future. The correct shifting should be performed in an opposite manner - to the right using the >> operation.

Hi Eugene,

another question regarding the roofing filter: How do you change the periods of the two integrated filters (high-pass and supersmoother)? Could you release the code for it?

Thanks.

Best

Hi Niels,

The code for all TASCIndicators is open source. You can obtain it by logging in to the Wiki (your Wiki account is synonymous to the website's account) and clicking on the green "Attachments" button on this page:

Home - TASCIndicators

For example, Ehlers SuperSmoother is contained within SuperSmoother.cs.
