Using the SLA (a crutch for the damaged or a new trader), a journey begins where one's learning to look at price in a new way. Not everyone prefers or is suited to this way of looking at price. And from the looks of it, there are very few who trade price this way. Those who do get to using it eventually can appreciate the meaning and the reasoning for looking at price as being continuous. Others may prefer whatever methods they use. Ultimately the objective is to make a profit and there are many ways of going about it, SLA being just one of them.
