Sorry you have just shared the same idea as I did. I'm sure nobody likes chasing high price or ATH for DCA. Yes if you have to have a particular price in mind as the range you want to DCA then it is still same point and idea that I shared. IMO, I don't like highs for DCA and I think likewise more hodlers don't too. So doing an analysis to wait for price getting there is part of trading also and DCA is either considered as hodling or trading depending on what you have in mind and when you decide to sell.
You do still not understand what DCA is, you're still trading, no matter how you put your average, or your budget, if you choose a moment for your weekly purchases depending on the price this is not DCA, it's pure speculative trading.
DCA means you have the same amount of $, at regular intervals,
no matter the price!
So if you have made 10 purchases every Monday of $100, you're not going to wait till Wednesday because the price might be lower and you're going to buy 300 worth of
BTC, that no longer fits the DCA model. The whole thing behind it is to not care about the current price and only with the future goal in mind, trying to catch the bottom every week just involves the stress DCA was supposed to get rid of!
