When deciding on trailing stops, there are several factors to consider, such as your time horizon, risk tolerance, market environment, and trading objective. Generally, the longer your holding period, the wider your trailing stop should be in order to withstand minor fluctuations and benefit from long-term trends. On the other hand, if you have a higher risk appetite, a tighter trailing stop is preferable to protect your capital from large losses and increase your turnover rate. Additionally, when the market is more volatile, a wider trailing stop should be used to prevent orders from being triggered by random noise and false signals. Lastly, if you have a more specific target profit in mind, a tighter trailing stop should be set to ensure that you exit your position near your desired level and avoid giving back your gains.
