There is only one basic rule in trading: buy low and sell high - LoL.
But to achieve this you need to study, you will not learn it here on a Bitcointalk thread. Go on youtube and look for trading tutorials, spend weeks studying the issue before risking real money.
Youtube is very useful to learn as bitcoin trader but on the otherhand, this forum will introduce to you how is bitcoin being used, what do traders really encounter with this and so on. I suggest that you read here because conversations here have been truthfully experienced by the traders.
You also need patience and will by the way.
True, patience is needed in trading here and if you will be reading about the experiences of traders here, you will find out that patience is a key to become a successful trader. If you are just starting, it is very normal to feel like okay and calm but when the market charts and prices starts playing with you, your calmness will easily be taken away from you. If you have patience you can avoid selling at bad prices like what most of the traders have experienced in here (including me).
I have tried watching videos and reading on the web about trading but real experiences beats documentation. Try to be persevere in reading and then relate it to your own experiences, in that way you will be able to understand how it happens more deeply.
I think what is trading requires is enough patience and crtical thinking to be very strategic when doing trading. Proper study of market movement can have more profitable result of trading. Because in trading, may result to gain or loss, so be wise enough.
Strategies can be developed of formed after fruitful reading. Traders need to know what a market chart is and more especially understand it but I don't think that proper study is needed, chart is a good visual tool already. It will be best if you will find someone who have been in trading before so if there is something you can't understand, you can ask him personally.
