Coffee Traders Discussion Forum
I would listen to Jack and if available to set up trading through his firm, I think this beats the alternatives you have discussed.
I am sure Jack can give more detail, but clearly his group is set up specifically for futures. Some of these other firms mentioned are not commodity specific and lack the deep knowledge in the space (IMO). We see how in touch Jack is with the physical side of the markets and to me this makes his connection with the platform quite reputable.
Just my 2 cents. Good trading.
