Min

The lowest value of the last N bars, this bar included, drawn under the candles as a stepped floor.

Min keeps the smallest of the last N values of its input, the current bar included. With the default input that is the lowest close of the last 60 bars. The line drops when a new low arrives, stays flat while that low is inside the window, and steps up when it drops out of the window.

How to read it

The line sits on the price scale, at or below every close in the window.
Where a close touches the line, the close is making a new N-bar low.
A flat stretch means the low is still inside the window; a step up means it just dropped out.

What it outputs

Min: The smallest close of the last N bars, this bar included, on the same scale as the candles.

Settings

Window: How many bars the low is taken over. Longer windows hold a low for longer and step less often; shorter ones follow the closes closely and touch them often.

Pitfalls

The current bar counts, so a close can equal the line but never fall below it: 'close below Min' never fires. Compare with Min a bar earlier to catch a breakdown.
