DislikedYes it can work, the rules are the important part... threads like James16 s/r PA for example can work, they try and make it simple, though it requires time and discipline. When I look at it, I know it involves lots of stuff that are in the rules which don't require you to have a phD understanding of on a deep level, but they are there for a reason. Time of day, and other market structure/micro-structure stuff is in there...
though, I would argue it is not mechanical 100%, it certainly requires discretion, I don't believe there is a system 100%...Ignored
Also I find having a solid set of rules will aid learning because you can reverse engineer the failures and impliment new rules thus improving the method.
