hi, I'm a newbie option trader. Im on optionhouse and trying to do a vertical spread but I get this message every time. What is the problem? I have sufficient buying power. My cash is around 4k and my margin is 7 k. The spread is a debit of $30 dollars on FEYE. Help?
Perhaps you are attempting to open the short position first. Try the long position first, when that has been filled open the short position.
