Not true: Depending on product and regulatory regime, for distinct trader/customer groups there may be distinct rules.

And if you are buying an instrument where you can lose more than you invested, the approach maybe wrong? :-)

This is precisely why shorting can lose more than you "invest", because you're not buying an instrument, you're selling it with the intent (or promise, depending on what kind of instrument it is) to buy it back later, hopefully at a lower price.

The risk is unbounded.

		Not true: https://en.wikipedia.org/wiki/Turbo_(finance) There are, as said, depending on juristic regime, products which do not let you lose more than you invested. On top of this comes national regulation: E.g. in some EU countries, retail traders are exempt from s.c. "margin calls" and the broker is required by regulation to "just close and not ask for more" Source: Im living in one of these EU countries
