Was i right in my chart?

 

Hi again,

Im still learning about trading and yesterday i did my first chart trend analisis, i dont understand it very well yet but practice makes perfect i guess, i made a trend and thought it would go up due to it touching this weeks support or what i think is this weeks support(am i right?), turned out i was right and it did go up, so many of you are asking your self, if he got it right why is he here nagging about it? well the thing is i dont understand why i got it right, it could have just continued going down and not bounce up, couldnt it?

Is there a way to know if it was going to continue going down or bounce back up or the way i did it is right?

Can any one explain the candle stick reading please? i read about it in the school but i dont really get how it works, how by looking at the first candle or the second they can know whats going to happen :/
