You may lose 20 times and gain only once but still turn out profitable in the end...
Oo... sounds impressive. Do you refer to luck in this one case or where and how do you trade? I mean you first have to overcome the fees, which is much on certain exchanges, and then you have to overcome the orderbook spread.
Do you have a good exit strategy or something like that?
Luck has almost nothing to do with this. I refer to the old trading wisdom which says that you should cut your losses short and let your profits grow. Indeed, it is easier said than done (psychologically mostly), since most people are prone to keep losing positions for too long and close winning ones a bit too early, but once you get the hang of it, you will see the light...
If you said that you go for gambling then it must be with luck, if you dont even have luck how are you going to gamble? Just purely using skill? I dont think something like that will happen without any luck of it and luck really have a great role in it
