Follow-Through Days

How traders spot the start of a new uptrend after a correction, with the real follow-through days after the April 2025 and March 2026 lows.

Confirming a new uptrend

After a market decline, the index eventually stops falling and bounces. Many bounces fail. A follow-through day is a way to judge whether a rally has real power behind it.

The common version works like this. Day 1 of a rally attempt is the first up close after a low (or the low day itself, if it closes well off its lows). Then, from about day 4 onward, look for a strong gain in a major index, often 1.25% or more, on higher volume than the day before. That is a follow-through day. If the index undercuts the low first, the count starts over.
