Rather than analyzing and making the decision on the basis of the current price action. A trader hold the trade out of the hope that it will move to the breakeven.
Several Key Reasons Of Sunk Cost Fallacy
The Hope Trade: Traders believe that it’s only the loss on the screen not the loss on my p&l until i book the trade. Meanwhile traders avoid looking at the market data which suggests the more decline in future.
Throwing Good Money After Bad: This includes the average down the losing position, until it reverse to the tp or at least breakeven.
Tying Up Capital: Keeping all the funds busy in the losing trade prevents you from investing the capital in the profitable trade.
How the Sunk Cost Fallacy Appears in Trading

Averaging Down Without A Plan: This involves using the more capital in losing trade. So that the entry price can come down to the lower and they can cut the trade at breakeven.
Over-Attachment To Research: When a trader spent countless minutes or hour’s in analyzing the market and charts. They believe that if they book the losing trade the their preparation will go in the waste.
The Danger of the Sunk Cost Trap
