dude, you are arguing with someone who has never made a dime. That guy should keep on doing what he is doing but he clearly has zero clue about risk and money management, this is apparently clear from his comments on stops, martingales, and his latest blow, reversion.
Quote from TraderZones:
This is not true. I have watched MANY systems of others crash precisely when a large move happens, precisely on this assumption.
Unleveraged stock trading, maybe.
Leveraged trading, your assumption is only true until it blows up.
The market does NOT revert 50%. Leveraged trading cannot afford to wait 9 months. The normal market is fine, but every year or two, it blows your strategy out of the water (leveraged trading).
