Might sound rough but the only conclusion I can draw from your posts is that you have been trading ridiculously large positions whilst you still have hardly the first clue what you are actually doing.
You wrote last November:
“I understand that exchange rates follow supply/demand but how and who physically decides the chart at any moment.”
Whilst that is a perfectly valid question from a Newbie on a site dedicated to helping beginners, it also shows that you are right at the beginning of your forex learning curve - but then in your post above you are telling how you are making and losing [I][B]thousands [/B][/I]only a few months later - when other Newbies would still be trading small lots on a demo account and studying…and then you blame the markets for your losses and predict that no one makes any money after their first year???
I think the most appropriate word in your post is “addictive”. But you are not addicted to the foreign exchange business such that you want to study it and be a professional class participant in it, no, you are addicted to the idea of making a million very quickly and driving around in your expensive car without even knowing what you are doing.
There are many posters on this site who have been trading many, many years and are giving sound guidance to people like you (you have already “met” some of them on your other threads). Ask yourself, would they still be here if they were not earning from their trade? But also ask yourself would they be here if they were multi-millionaires from their trading?
Although I have no evidence for it, I do suspect you are right about robots. Markets are not homogenous or regular in their movements and characteristics and for that reason I do not see how a robot can be programmed to perform at all times in all market conditions and to self-adapt to the gradual structural changes in the way markets move. But I have no experience in these things.
I think you have to decide are you only trading for the lure of the big money or are you genuinely interested in foreign exchange and wanting to learn about it in a professional manner? If it is the former then find something else to do. If it is the latter then prepare yourself for a long and gradual learning curve which will incrementally reward you both in job satisfaction and financially, and maybe one day reach a stage where your earnings are actually a source of pride and satisfaction to you, especially being the result of your own dedication and efforts.
