BUY LOW - SELL HIGH
Based on this motto, the time to sell is when the price rises and time to buy is when the price is low.

And that is what I always aim to do. The hard part is holding when you are stuck. You just want to sell and take your losses and keep trading when sometimes it just requires a bit of patience to wait until the price rebounds. Anyways, I haven't made much trading as it is hard to time the market and prefer to stick to the old buy on HODL.
