Simple strategy will work like share trading, because you can hold it until you want, so no pressure you to sell, I am using averaging strategy, when the price drop, I will buy again, when the price up I sell some of them, then wait for the drop. There is no matter which time you enter, only matter is you must have some good amount of money and trade with small percentage.
Those you mentioned is totally basic rules for the traders of doing in all trading exchange platform. That's the same thing what I did for my daily routine in the exchange sites.
