Are you serious? Dollar cost averaging as a market maker is NOT the holy grail, it is the way to get whiped the fuck out of the business! Buy on the bid, price moves against you, buy on the bid, prices moves against you, buy on the bid, price moves against you, buy on the bid prices moves against you... repeat until position size is too big, and your offers still aren't being taken, so you dump on the bids below you... congratulations, you just helped some trend traders out and lost yourself money. Great job!
