I'm more concerned about whether this position will trigger a sell signal.
This kind of position is most prone to getting whipped out, so let's prioritize discipline first:
First, observe if the 5-minute chart reclaims the key level, the 15-minute chart reclaims the previous high, or if a breakdown forms a higher low—these all indicate failure.
Next, focus on three types of short positions: failed breakout attempts, end of rebound traps, and key support breakdowns.
Additionally, stop-loss should be set first before discussing the direction.
Finally, avoid chasing in the middle; wait for clearer levels.
