Futures download S&P500, WTI etc

Hi. Im new to Amiquote. Does anone know how to download indexes and futures for OIL (WTI) and S&P500?
I tried to add symbols in different combinations for S&P500:
CME_MINI:ESH2018
ESH2018

But all available Amiquote Sources fails to download it.

Can anyone explain on symbols rules (like MARKET:tiker name, any additional symbols, etc.)?

Thanks!
