Advice: How much margin to set stop loss or stop limit?

Many short traders or big money managers here. This question may be for regular, long position investors.

Some books say to look at the support level but it is not an easy job.

Other books say to set a margin (loss) that one can tolerate.

Even other books say to hold your stocks forever. I think it is dumb to do it this way.

In today's market, in order to preserve gain (or reduce loss), what you think a stop loss percentage should be for a medium volatile stock?
