Capital is at risk. Claughtdeck explains ideas for a UK reader. Nothing here is a personal recommendation, a tip, or an invitation to trade. Read the disclaimer.
Issue note · 27 October 2026
Claughtdeck is a UK journal from Ivybridge about the tempo, the tax, and the temperament that separate day trading from long-term investing. We publish explanations. We do not publish signals, tips, or promises of income.
ISA 2026/27
£20,000
Adult annual allowance. Unused room does not carry forward.
CGT exempt amount
£3,000
Then 18% or 24% for 2026/27, depending on your band.
UK share purchase
0.5%
Stamp Duty Reserve Tax on most electronic buys of UK shares.
Dividend allowance
£500
Above that, dividend rates rose for basic and higher rate in April 2026.
Same day
Open a position and close it before the session ends. In the UK that might be a share, a contract for difference, a financial spread bet, or a currency pair. The clock is the product. Costs, leverage, and attention decide whether the clock is kind.
Many years
Own assets you are willing to hold through dull years and ugly ones. In Britain the practical homes for that patience are a workplace pension, a SIPP, and a stocks and shares ISA, often filled with funds or investment trusts rather than a morning of tickets.
| Question | Day trading | Long-term investing |
|---|---|---|
| Horizon | Minutes to a single session. Flat before the close is the point. | Years, often decades. A bad month is not the thesis. |
| Usual UK home | A dealing account, CFD account, or spread-bet account. Rarely an ISA, because an ISA is built for holding. | Stocks and shares ISA, workplace pension, SIPP, sometimes a general investment account once allowances are used. |
| What usually hurts | Spread, slippage, overtrading, leverage, and the urge to “make it back” after lunch. | High ongoing charges, panic selling, and concentration in one story. |
| Tax character | Depends on the instrument. Spread-bet winnings are often outside capital gains tax for a private individual. CFD and share gains often are not. | Growth and income inside an ISA or pension are sheltered. Outside them, CGT and dividend tax can apply. |
| Time demanded | Presence. A job that already fills the London session is a structural problem, not a motivation problem. | A plan, a funding habit, and the nerve to leave it alone. Hours, not a career, unless you want it to be one. |
Figures on this page are for the 2026/27 tax year as publicly described, and they can change. They are not a calculation of your bill. See UK tax and costs.

The first half-hour after 08:00 is loud. Volume is not the same thing as information, and a red candle is not a comment on your character.

An arithmetic illustration of £250 a month. Smooth rates are a teaching tool. Markets do not pay them. The table is still worth walking through.

A composite scene, not a boast and not a confession from a client. It is about the rule you write down before the day begins, and then obey.

We will not tell you what to buy this morning. We will not introduce you to a broker for a fee dressed up as research. We will not show a screenshot of a winning day without the losing month it sat inside. If a sentence on Claughtdeck could be read as “this will pay you”, it is a sentence we have failed to edit.
