Getting trapped is not a dead end, but stubbornly holding on is. Don't think you can rely on miracles like "lying flat"; first, distinguish the strength of the trend: when the trend is upward, buy on dips and sell on rallies, using swing trading to lower your holding costs; when the trend completely reverses and support fails, don't hesitate—cut losses to protect your principal. Holding heavily and stubbornly, or adding to positions against the trend, will only deepen the trap. Control your impulses; operating in line with the trend is the only way out of the predicament.
