Make sure first of all that you take the right knowledge, this can be done in many forms by taking a course or simply doing your own research on the internet youtube google.
I personally recommend
find someone who has the right knowledge available to you.
look for a good teacher someone who has the knowledge available in the form of a course and who has already gone through all the steps and can therefore share his experience.
It is also important that you find the right broker.
A broker that I can recommend can be found here, broker is regulated and therefore reliable.
As said the broker and the right knowledge are critical, start with a small live account and get the feeling of trading in your hands, to actually win but also learn to lose with good money management.
While the forex market is largely reliable, in that prices reflect all the information available at any time, in many cases you only need to be slightly faster or smarter than the average market participant to start a winning trade position. But behind this position initiation is a set of assumptions and a coherent disciplined understanding gained through the study of the market and the practice of execution of the trade. No less critical is understanding how to use your forex broker’s provided platform profitably.
