I cannot argue with you on this exact topic. At the same time there are traders and simple ideology holders, that will keep a principle of "never double up, does not matter the situation". Meaning that they will accept the loss, and open a new trade, on the same exact rules, the same exact ordersize!
Cheers!
P.S. at the moment, when Moonbot community grows to a number big enough, to implement new features with simple voting, you will see all the necessary features, that you find necessary as a trader.
