I only have a small knowledge of the cocoa market, but it would appear to be made up the big buyers, Nestle etc and hundreds of thousands of cocoa farmers, plus of course speculators. If supply demand get out of whack, then it is feasible for a large speculator/hedge fund(s) to force the market to correct itself, either up or down. I am continuing to hold long positions, but often as a marker, that is built up. UK Cocoa is what I am currently trading. I would like to know if the US has more liquidity. I guess the question is what market should I use to trade cocoa in the US. I have just added IB as my broker.
