How to trade SPX500

Hi

Is it possible to trade spx500 in forex? If so, what currency pair is it?

Thanks

The SPX is an index, so the answer is no.
You need to find a broker offering the SPX 500.
Currency pairs are a completely separate instrument.

It’s not forex, and not a pair.

Some brokers allow equities, commodities and futures to be traded from a single platform.

Look at GCI Financial for an MT4 platform that will let you trade all three. S&P is included there.
