It highlights bars featuring a micro-absorption pattern: a narrow tail of opposing delta at the bar's extremum followed by a uniform body with delta of the same sign. This pattern indicates that aggressive orders at the edge of the bar were absorbed while the rest of the bar moved in the opposite direction. The indicator spares traders from manually scanning clusters for this pattern, leaving the final analytical decision to the trader.\u003C\u002Fp>\n\u003Cp dir=\"ltr\" data-path-to-node=\"20\">\u003Cstrong data-path-to-node=\"20\" data-index-in-node=\"0\">How the Indicator Works\u003C\u002Fstrong>\u003C\u002Fp>\n\u003Col dir=\"ltr\" start=\"1\" data-path-to-node=\"21\">\n\u003Cli>\n\u003Cp dir=\"ltr\" data-path-to-node=\"21,0,0\">\u003Cstrong data-path-to-node=\"21,0,0\" data-index-in-node=\"0\">Level-by-Level Delta\u003C\u002Fstrong>\u003C\u002Fp>\n\u003Cp dir=\"ltr\" data-path-to-node=\"21,0,1\">On each closed bar, the indicator pulls the full footprint (bid and ask at every price level) and calculates delta at each level as ask minus bid, from bottom to top.\u003C\u002Fp>\n\u003C\u002Fli>\n\u003Cli>\n\u003Cp dir=\"ltr\" data-path-to-node=\"21,1,0\">\u003Cstrong data-path-to-node=\"21,1,0\" data-index-in-node=\"0\">Tail Detection\u003C\u002Fstrong>\u003C\u002Fp>\n\u003C\u002Fli>\n\u003C\u002Fol>\n\u003Cul dir=\"ltr\" data-path-to-node=\"22\">\n\u003Cli>\n\u003Cp dir=\"ltr\" data-path-to-node=\"22,0,0\">Bullish bar (close above open): a sequence of levels with negative delta at the very low.\u003C\u002Fp>\n\u003C\u002Fli>\n\u003Cli>\n\u003Cp dir=\"ltr\" data-path-to-node=\"22,1,0\">Bearish bar: a sequence of levels with positive delta at the very high.\u003C\u002Fp>\n\u003Cp dir=\"ltr\" data-path-to-node=\"22,1,1\">A tail is valid if its thickness ranges from 1 tick up to the Max Tail Levels setting and does not occupy the entire bar.\u003C\u002Fp>\n\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Col dir=\"ltr\" start=\"3\" data-path-to-node=\"23\">\n\u003Cli>\n\u003Cp dir=\"ltr\" data-path-to-node=\"23,0,0\">\u003Cstrong data-path-to-node=\"23,0,0\" data-index-in-node=\"0\">Body Verification\u003C\u002Fstrong>\u003C\u002Fp>\n\u003Cp dir=\"ltr\" data-path-to-node=\"23,0,1\">Every level beyond the tail must feature a delta of a single sign: positive for a bullish bar, negative for a bearish bar.
