Succinct.  Exactly.  Dollar Cost Averaging.  For buys and when buying call options or selling puts, I increase commitment while maintaining the core strategy.  Highs and lows are arbitrary in an irrational market.  Profits can be increased if buying at &quot;relative&quot; lows or selling at &quot;relative&quot; highs.  If a stock that trades at its highest yet value of $100&#x2F;share falls to $80&#x2F;share over a week because of a lawsuit <i>claim</i> or other similar construct, but the company is otherwise outperforming, that may be a buying opp (it may be a total loss, but that differential is risk&#x2F;opportunity).  That stock, at $80&#x2F;share is at a &quot;relative&quot; low as compared to its high of $100.  That is what I meant by low and high.  Perfect maximization is possible, though almost always unlikely.  Which is why your DCA strategy should outperform (depending on your investment choices, of course).
