You need to choose such complexities with which you will be comfortable working, because your result will depend on it.
Today, there are no special difficulties in order to choose a reliable and safe broker with whom you can earn money, you just need to study the conditions that he offers.
In my opinion, FP Markets has the lowest spreads and commission costs are lower than other similar brokers. It begins at 0.0 pips for most parts of the day, and it also stable even during high volatile market movements.
From the lot of brokers that I have tried so far, fxview has been the best for low spreads, even commission is just $1/lot per side.
