Turtle Soup

A new extreme of the last twenty sessions, where the previous extreme was at least four sessions old. From Street Smarts, both sides, on the daily.

What it looks like on a chart

A horizontal line at the new extreme, drawn forward from the session that printed it.

The age of the predecessor is carried on the event because it is the half a reader can check, and the half most implementations quietly drop.

Settings, as they are actually applied on each timeframe. A dash means this scanner emits no settings string. Where a number differs by timeframe, that is a span of chart time resolved into bars.

Not on M15, M30, H1, H4. It is defined in SESSIONS — twenty of them — which is D1.
