I believe coffee still has some upside, it will probably reach $290 within a few weeks. Then the demand would start to wear off and soon it will be back to the $125 range. Coffee rarely traded above the current value, any value above $250 is short-lived. So if you are into probability, there is a very high chance coffee will start to reverse its direction. But as it's advised to never go against the trend, wait for the trend to be broken before you go into any selling positions.
Probably a good time to start selling coffee in small quantities, and increase the quantity when the coffee reaches near $300.
