Stop loss at 7-8%, this is not a negotiable number. Once the decline reaches this line, liquidate immediately. Don't rely on a rebound; capital preservation is always the top priority.

When reversing, take profits at 20-25%. Many people are greedy, hoping for more gains, but as a result, profits evaporate without a trace. Take advantage of the momentum and lock in gains quickly.

Once the key support is broken, the chart has already spoken clearly. Instead of fighting the trend, go with the flow—the market always wins.

Also, do not add to losing positions. This is the most common mistake, which only turns small losses into big ones.
