Scalpers will depend more on indicators than news. Scalping is just a waste of time in my opinion. The riskiest trading types are scaloitand day trading. Most traders that fall in this categories are losing while swing traders and holders are very patient and make more money from trading. They are also not time consuming like scalping and day trading. If you are using fundamental analysis to trade just as you explained and not trading often, you are not really scalping in my opinion because you do not trade frequently.
