I'm not reading this, spread betting tax advantages will swallow any alpha you will find in the futures market
Never yet met an accountant who understand options- but for tax it's simple P&L . Turnover minus allowable deductions, don't ever try to explain options to HMRC!
Turnover is the actual money going through your account - so you might sell a put for 20 but have to buy it back for 30, but you roll it and take in 40, then close that out for 15. That is the simplest options trade I can think of! Try explaining strategies to HMRC and you will be arrested for heresy.
Turnover is 20+30+40+15= 105 but profit is 15 as I inderstand it. Turnover is money in and out
How much of your pnl is comission and fees? Is it >45%(top tax rate UK)Spread betting is more expensive though.
