Best Day To DCA

Each bar is the average extension of price above its 50-day SMA for that weekday, across the full history. The weekday with the lowest average extension has, historically, offered slightly cheaper buys relative to trend.

Honest framing: the differences are tiny — fractions of a percent against daily volatility measured in whole percents. If a weekday edge exists (weekend closes have historically been marginally softer), it's a tie-breaker for an existing DCA habit, not a strategy.
