I don’t know that the prices during the DCA period are trending upwards, I have no information about short term fluctuations other than they exist.

I have no reason to believe that over the relatively short period of DCA that there is specific upside or downside coming along immediately, but I know that there is noise in the pricing. The rising trend I’m betting on is further down the line and very slow.

You’re adding assumptions that support your view, rather than addressing the problem as stated.
