Sometimes the length of time that you have between closing out one position, and opening the next one can have an impact on your performance.
Fast re-entry is when you are entering the market with only a small break from when you last exited a trade.
If you see that these “fast” trades underperform, then you need to focus on taking a break between trades, and also ensuring you are not carrying the emotions from one trade into the next one.
On the flip side, it may be you can get into a “zone” where fast trading really works for you when you catch a trend.
In either case, know your specific strengths and weaknesses, and put some structure around your trade execution to ensure you can manage your own emotions.
