Hi guys, i am new to futures and i have a really basic question about rolling over to the next contract. lets say i am long March Corn right now from 223. my stop is at 218. and i wanan roll over to the May Contract and the spread between them is currently at 10.50. do i simply roll over to the May contract by paying the higher price and moving my stop at 218 up another 10.5 to 228.5? what if the spread narrows/widens? do i adjust my stops accordingly? thanks for any help, i am kinda confused by this.
