Best time of day to set a daily recurring DCA buy?

I am thinking of changing my weekly DCA to a daily buy. Does anyone know what the best time of day would be to get the best price on average?

Is it typically a bit lower in the early morning like 5AM before people are awake and buying? Or the middle of the night? Or set up multiple smaller buys throughout the day? Or does it not really make any difference?

Just want to set it and forget it at the optimal time.

Thanks for your insights!
