These indicators are not for making EAs but for live trading manually. I came across the Lab Trend (coded by Igorad) with an alert when colors change, and it has high low lines too. It is similar to Silver trend but looks like it may be better for trading live. I tested it in 1 min charts, and it doesn't seem to repaint previous bars.

The Fisher m11 (solar) that I posted doesn't repaint and can be used for an EA.
