A retail trader of equities and options may believe that his technical signals and fundamental analysis is superior and smarter than the other retail traders. Maybe for some it is true.
For a lot of others, it is not, so their profits and losses are random.
As a retail trader, how can I go about trying to find trades with a positive edge. I am just looking for general guidelines. Because specific guidelines in this regard will only work in specific situations.
As a contrast, a market maker has a clear and defined edge that is easy to understand intuitively. The edge is the bid ask spread. It is clear and measurable.
How can a retail trader go about finding trades with a clear edge? Is it even possible based on only publicly available information ?
