Binary options are not the same as spread betting and were banned in the UK since 2 April 2019 by the FCA. This means that no broker UK broker can offer Binary options.
Binary options were riskier with short expiry dates (between 5 minutes and 24 hours) by betting on the price being higher or lower than the current price within the timeframe set. A spread bet on the other hand allows UK trade to trade without an expiration date, and you control your profit and risk potential, allowing for unlimited market gains.
