you need to provide a lot more information than this if you want a proper answer. otherwise I have to guess an my guess based on what I have seen from new traders is that you are not "trading" you are "gambling". this means you never buy something because you analyzed and came to a logical conclusion that it will rise, instead you buy something because you felt it may go up based on your gut!  and well that is the definition of gambling. the result is that you sometimes make some profit and sometimes lose where the losing part is the dominant part.

solution? start learning how to trade and stop trying to guess the market randomly. start learning about things that affect it.
