AbsoluteReturn

The absolute return of a pair's closes over lagcandles candles (the lag, default 1): close − close N candles ago, i.e. the price difference in the pair's quote currency.

• Indicator: lib's Returns.AbsoluteReturn over the closes (as double), wrapped in WarmUp.
• Warm-up: until N + 1 candles are seen there is no return. The changed event carries { "value": null }, and the same is saved, instead of an error.
• Value: { "value": 1.25 } — a price difference in quote currency (USDT for a _USDT pair); 1.25 means the close rose by 1.25.
• Not the relative return: RelativeReturn publishes (close − close N candles ago) / close N candles ago (a unitless fraction); LogReturn publishes ln(close / close N candles ago).
