FCA considers SB as 'betting'. The laws surrounding it consider trading SBs as 'gambling' too. Not much comfort for the talented 10% who could make money, given a fair chance.
As a senior writer, you should have known that market makers make up their own prices as they go along, suspending trading when it does nt suit them, or various other techniques mentioned in several posts, to track and destroy any trader who does turn out to be successful.
Financial spread-betting is classed as a form of gambling in the UK but it is regulated by the FCA, not the Gambling Commission. The FCA is the regulatory body for the UK financial services firms and UK financial markets, enforcing in one of the tightest regulatory regimes in the world.
Yes, the SB firms make up their own prices, because they don't offer direct market access. Yes they move spreads and suspend trading when risk to themselves is high. But we all know this and it is legal. It is not cheating. So anybody who knows these things and that this access is therefore structured to the advantage of the firm especially against the intra-day trader but carries on trying to scalp via SB is taking an unacceptable risk.
