By the way what really is risk management? I am still trying to figure that out.
It's too bad that the OP chose a really crappy title and a somewhat misplaced premise for the most under-appreciated and least well understood aspect of trading system strategy.
You take a trade entry, and one of two things are going to happen: you stop loss, or you hit your profit target. It seems like 99% of the effort goes into the trade entry machinations and the rest is an afterthought.
In my opinion, much of this "proper trade management trumps an entry edge" philosophy comes from the exploits and legends of a small number of certain skilled and well positioned pit traders. Especially around a market open, independent pit locals would get alot of orders thrown at them from floor brokers. If there was any balance to the market orders those locals just cleaned up. Being able to have immediate access to that order flow and having the situational awareness to find other orders to lean on meant that certain (privileged) floor locals could buy bids, sell offers, and get out stinkers with a scratch. For size.
Being one of those 1% of locals with access to that kind of order flow, the capitalization, and almost certainly the
good graces (yeah, it was not a fair democratic process) of those floor brokers
was into and unto itself a legitimate and powerful edge. Of course, those days are decades gone.
You do, of course, require a statistically valid entry edge. It doesn't need to be huge (and truthfully almost certainly your edge won't be more than a few to several percentage points above B/E - if your edge is legal) but if your W/L ratio is > 50% over a protracted period of time and through several market cycles then that is all that is required -
provided you have proper trade management rules that you do not sabotage.
