### <summary>
### EMA cross with SP500 E-mini futures
### In this example, we demostrate how to trade futures contracts using
### a equity to generate the trading signals
### It also shows how you can prefilter contracts easily based on expirations.
### It also shows how you can inspect the futures chain to pick a specific contract to trade.
