Are people going all or nothing on profits, or skimming on profitable trades?
In highly volatile equities, I often skim some profits along the way. If price bounces off an upper trend line, I prefer to take some profits here as well (rather than wait on the right side exit). However, such actions remain a personal choice. On equities which show a more gradually increase in price over time, I frequently allow the entire position to chug along until reaching my target exit. I hope you find the above answers useful.
