Thought as much the moment I read through his explanation but since from my experience in the industry I have come to understand that different strategy works just fine for different Individuals (traders) therefore maybe this is just what works for him. For other reader that are hoping to profit from trading and looking for an easy strategy to follow, taking note of what this user has highlighted is very important to avoid losses.
Also I have come to understand that most short term profiters aren't actually the best market analyzers but just those with luck on their side resulting from seizing the opportunities when it present itself.
Agree on what you have said on here and also to those things that are being mentioned on op, it does really look like an easy strategy yet you are just comparing daily open and closes and trying to differentiate or compare it on between timeframes,it does sound really basic but doing the actual stuff is just hard as hell.Decision making will really vary on your experience and knowledge.If we have just recently trying
to do this strategy then its either it would work or not on a certain trader or individual.Experience is what matter most.
