Follow-Through Day (FTD)
A strong up-day early in a rally attempt that confirms a potential market bottom or new uptrend.
A follow-through day (William O'Neil / IBD methodology) typically occurs on the fourth day or later of a rally attempt, when a major index rises meaningfully (often ≥1.5%) on higher volume than the prior session.
FTDs are used as a coarse "risk-on" switch for the broader market — not a stock-level entry trigger. Swing Edge's market regime logic uses Nifty trend and breadth rather than a strict IBD FTD count, but the concept informs how aggressively breakout setups are gated in bearish conditions.
