I assume the individual trader is at a huge disadvantage compared to large commodities trading houses. These large firms have all the resources, experience, expertise, and deep roots in the industry. Not to mention the capital for detailed weather reports and forecasts, niche sites for market analysis and fundamentals that are very costly.
How is the individual trader able to compete? Or are they mostly people from these big firms that leave and trade their own account.
what did you mean when saying "compete"
the roads of individual and those corporations rarely cross in the market
so i would rephrase your question: how an individual can better the so called professionals in this game?
the answer is simple: through extreme individual talent and personal abilities (simple to say but very rarely happens)
the talent and abilities can not be replicated by any corporation (their can hire talent , but it is something that is not available on mass scale to build a business upon)
that's why most corporations not in the business to make money on trading in the sense that individuals attempt, they make money by being a broker or utilizing they place in the market (market makers etc)
that's why institutional traders in reality are mostly executioners of orders, if you pull them from their jobs and make them trade their own money for living most will show miserable results ( same as general public) ....
why is that?
because so called professionals do not know how to make money on the market (same as general public ), corporate professionals mostly make money off the market skimming (in different ways) off the huge flow of money that goes thru the market
that's why when big corporations abandon their role as brokers or market makers (based on the place in the market) and invest directly in the market results are usually miserable - they go out of business
so when average John attempts to trade on his own what he is really saying by his action is : "I am better that the so called professionals, I can do what they were not able to do - I will make money on the market !"
but most of the time average Joe is what it is - just average Joe (without extreme talent or abilities) ... and he surely fails
