At the end of the day, what you are tracking is the change in your PnL. Leverage can be a proxy for volatility. When you apply both, leverage to a highly volatile asset, that's what takes you into a difficult to manage risk management situation where the PnL swings can bring you to ruin.
"Trading on leverage"... any market... is mostly a matter of greed and hubris. If you get away with it, fine. Leverage is a "2-way street", so don't be surprised if it bites you in the butt.
So for every CL contract traded, one should have ~$45k to avoid being greedy? It depends on an individuals trading style...but in my opinion, if your are trading intraday, you'd be crazy not to lever up.
Crazy or not, leverage increases risk... regardless of how "clever" a player you perceive yourself to be.
I absolutely agree with you. But you have to have exposure to risk to make money. Sometimes leverage is the only way to increase exposure enough to achieve reasonable returns. Especially in forex and futures
