Don’t marry a position
From a trading perspective, marrying a position means a trader has become emotionally attached to holding it, especially in the face of strong evidence that this is not the right position to be in. This particular trading error can often result in excessive losses and wasted margin because a transaction intended to be a short term trade can turn into a longer term “investment” that may never ultimately show a profit. Successful traders generally avoid getting emotionally involved with holding a particular position, especially when the market is clearly telling them they are on the wrong side. Remember, humans are intended to marry their spouses, not their trading positions.
