Options Expiration Day

Taking into account emini index futures and ETFs trading before the market opens, we may expect strong positive opening. This is the last day of October's options. I would be very cautious today as we may see wild swings, especially at the begging of the day.

I would go today with 15-min (1 bar = 15 minutes) chart today as it faster react on the price changes than 30-minutes chart.
