Now you can trade Futures with our good friend Robin $0.5 + Fees per contract https://robinhood.com/us/en/about/futures/
I mostly trade the micro but did trade the mini russell last week That cost for 1 contract was $1.40 for the exchange and regulatory fees and commission at 50 cents Total $1.90 The micro cost for 1 contract is 37 cents for exchange and regulatory fees Commission at 50 cents Total cost .87 cents Again i have gold which reduces the Commission by .25
It is coming soon but some had early access as of last week in January Yea for the cost you can't go wrong. You already cover the cost in 1 single point.
They have started offering accounts in the UK. Only stocks so far, maybe options were being added in these days and soon futures. Like Schwab with TOS.
