The problem for many traders is that the places they tend to put stops are also great locations for a reversal trade.
They have this internal debate because they notice that over a short duration of time there is in fact a positive edge to NOT stopping out of a trade.
As a general rule though, breakout traders tend to favor hard stops, reversal traders often favor time based exits/stops.
So for example a breakout trader looking for momentum will be willing to get out of losing trades when the edge is not with them over a shorter time horizon, because it is the price they pay for the liquidity of exiting the position. The shorter term trader, however, might actually be entering the trade when the breakout trader exits, and provides the liquidity and gets the shorter time horizon edge.
