this is my code to get commodities ricCode
filter="TickerSymbol eq '" + code + "' and ContractMonthYear eq '" + date + "' and AssetStateName eq 'Active' and RCSAssetCategoryLeaf xeq 'Commodity Future' and ExpiryDateString ne null",
I use below param to get code , it will return error messges.
"code":"IF","date":"Mar 24"
but I use below params , it's right
"code":"TF","date":"Mar 24"
They are all commodities codes I found on the Internet, I can see price info in other web by IF2403,TF2403,
Why is using the first code problematic(IF2403)?
