Many people don't understand the significance of adding to a position. Adding to a position is about using a very tight stop-loss to achieve a high reward-to-risk ratio. Take tonight's trade as an example: entering at 3190 with 1% of your capital, adding at 3160 with 2% of your capital, so your average entry price becomes 3170. The recent high rebound was to 3194. With 3% of your capital, you could capture 24 points; with 1%, you capture 30 points. The 50-point profit is much higher. My strategy is mainly short-term: with 1% of your capital, taking 25-30 points can be enough to exit most positions, while keeping some reserve for the second and third targets. When adding to a position, capturing 20 points should be enough to exit most, rather than sticking to the initial first, second, or third targets.

Everyone should spend at least 30 minutes watching the US stock market because of its quick volatility. Usually, within 30 minutes, you can resolve the trade—either stop-loss or take profit. After all, you're not in my community, so I can't notify you immediately to take profit, reduce your position, or stop-loss.

Please refer to this: my added positions generally tend to rebound. How much you want to profit from the rebound depends on you. Unless there's a news event causing a sharp spike, anyone who comes in will likely have to exit at a loss.
