This year wasn't really good for calendar spread trading. Last winter, nat gas price exploded then quickly collapsed in the winter. It made this year's winter spread widened. I bet its winter spread narrowing and made some small profit. Actually, betting to winter spread narrowing is not recommended. I closed Nov23-Dec23 spread and currently holding Nov24-Dec24(betting to spread narrowing) and Jun24-July24(betting to spread widening). Unless you touch Widow Maker spread (Mar-April), nat gas spread trading is relatively safe.
