I understand what you are saying, but I'm inclined to agree with @JacoAF
Specifically his points on over trading.
And you just confirmed what I'm trying to say, 'My point is that leverage does limit risk but it limit profit as well.' - On the account type and capitalization, I lean more (in his case) to limiting risk over increased profits (adversely, increased losses) - the double edged sword.
Long term on a commodity (oil - historically all commodity prices increase), with a bearish outlook (to prevent negative swap) in my view means you have to limit your risk over increased profit.
This kind of reminds me of the cringe worthy adverts, 'open your standard account today with up to 1:3000 leverage with only $5!!!' - and then new traders wonder why they battle so much.
I prefer having a creeping margin call that will last long enough to fund my account, close trades I (not the broker) want to close and examine what went wrong while preserving as much of my equity as possible, than one moment all seems fine and the next moment all my trades are closed out and my balance is zero... just because I decided to take a quick shower / make coffee.
Maybe we disagree because I'm looking at the case of @andromeda1
and you are looking at it in general?
For every loss there should be at least an equal and opposite profit.
