Basic Trades Short Call ' A covered call is when the trader writes or sell the call and then takes an opposite position in the futures. For example, selling a $4.20 March corn a call for $.30 per bushel and buying one contract of March corn futures. The trader profits if March corn does not rise above $4.50 and would profit March corn traded or expired between $4.50 and $3.90
