There are two things you need to check before choosing a broker (and this is not for newcomers only, its for every single trader out there):
1. If they are regulated. Usually regulated brokers have their licence numbers published on their homepage for you to check that they are legit. By licence, we mainly mean licence from accredited jurisdictions like EU (UK, Cyprus etc) or Australia. At least that way you know that you have some level of protection against scammers.
2. Fees. Everybody charge fees. Very few people pay close attention to them. Fees are not only trading commissions. There are hidden fees like spreads and swaps. Most regulated brokers publish these fees on their website and you should always calculate how much you are going to pay your broker for every lot you trade.
If you use these two factors for your research, it won't be hard for you to choose the cheapest, regulated broker.
