I've got no rule of thumb -- it varies widely depending on the security it represents.

Oh wait, there is one rule of thumb -- never, I repeat, NEVER use a market order on options. There are no MMs and the rules are drastically different. Level 2 literally means nothing because anybody can create (write) shares (option contracts). I've read horror stories and experienced some minor ones myself using market orders on options.
