Full round-tripper

A full round-tripper is a trade that went into profit, sometimes substantial profit, and then reversed all the way back down to breakeven or into a loss before the trader closed it out. The name comes from the price making a "round trip" — up and then back down (or down and then back up for a short trade) — leaving the trader worse off than if they had simply taken the gain when it was there.

It happens because the trader had no plan, or had a plan but did not follow it, for locking in unrealized profit. Unrealized profit is the gain shown on an open position before it is actually closed; it is not real money until the trade is exited. Without a trailing stop, a partial take-profit, or a mental rule to move the stop-loss order up as price moves favorably, an open position can drift back through all of its gains and keep going, sometimes hitting the original stop-loss and closing at a loss.

The nuance that trips people up is that a round-tripper is not the same as a trade that simply loses from the start. It specifically describes the psychological sting of having been "up" — sometimes way up — and watching it evaporate. That gap between the paper gain and the final result is what makes the term useful: it points at a management failure (not adjusting risk as the trade moved), not necessarily an entry failure.

The original wording given for this term — profit target barely missed, then price drops to the stop loss — describes one specific version of a round-trip (a near-miss on the target followed by a full reversal to stop), but the term is used more broadly for any meaningful reversal of open profit back to flat or negative, whether or not a formal profit target was set.
