There are lot of common mistakes every trader do when they are new. I also did the same. Like opening trade position before big news events and after the news events. Opening too many lots is another mistakes. Risking more than 1% of the capital is also a mistake. Another big mistake is unrealistic expectation. We come here to make double, triple of our capital over night. But it's the biggest mistake one can have. We also make mistake in choosing broker.
