Professional traders don't just rely on fundamental analysis. Technical analysis (reading graphs and understanding how the market sentiment reflected by them will affect the future) is also a very important part of successful trading.
I don't think anyone thinks that they can move the market price to their favour unless they're a whale, in which case they can.
Everybody uses his own strategy, or technique to trade, and I dont know a single trader that only uses technical analysis, it is indeed very useful, but you cannot rely on it, and put up the money only because the fundamental analysis looks really good for the trade that you wan't to make.
You should mix up different techniques for spotting if the trade is made correctly, always double-check if the stop-loss/ take profit is typed correctly, because once my friend has made a typo in stop-loss at FX market, which pretty much caused him to lose 1/4 of his balance.
Be careful about every analysis, you should always mix them up to see more possible ways of price movement.
