sometimes when I'm interested in buying a coin I just know that if I buy it the price will go down and if I wait the price will go up. I can't explain it it just f***ing happens...
(I did buy and it did go down...)
Stop trading, that is the best advice I can give to you, trading is not supposed to be about premonitions or anything like that, you need to have a reason to make a trade, if you are not able to understand the charts maybe you could just trade the news, we have known that bitcoin was going to be forked twice for some time, you could have bought and wait for the bull run, as you can see there are several ways to trade but for what you are describing, it seems you are doing it all wrong.
