I don’t really advocate buy and hold strategies. Especially when they go with sustaining significant losses.
Trading is a hard work. There are many different ways to trade successfully. Each trader has to find his/her own way for doing it. Test other traders’ methods to find out what fits you. I prefer methods that follow repetitive market behaviors, such as trends.
Better back-test your methods before you go live with them. I prefer simple trading approaches as they are more robust than others, more complex or data-mined ones in the longer-term.
Control position sizing. Don’t make trading a stressful activity.
Plan your trades and trade your plans.
