While trading we have to follow few rules and without following those rules there is no way to be a successful one except a successful by chance. There are lots of rules of them greedy plays a vital role. While trading never be greedy. If you become greedy while trading then you can be assured that there is 90% possibility to be a lessor.
I agree with you. Having rules is vital when you are trading and without it you will be out of the game in a jiffy. As I learned when I was new to trading rules will save you, always set reachable target price and a reasonable target loss. Always follow that target. It does not matter if the coin continue to rise because sometimes waiting for a higher price is deadly. Sometimes instead of going up it will goes down. As my mentor told me a gain is a gain, Lock in your profits.
