Trading costs,
At this moment I use a broker that charges 50 cents plus 0.01 cent per share per transaction in New York. So the trade of 15 shares at 12.335 could be done. 15 shares would mean a fee of 51 cents, so two ways is one dollar.
So you can have a lot of different individual shares without using LD-AIM.
Also ETFs can be traded for free, so the buy and sell size could be 1 share. Using the parameter settings (10,10,6,5) you basically have a 20% hold zone when trading 1 share per transaction.
This is a Dutch broker, but surely you have equivalent price settings in the US.
