The reason that we don’t currently pay capital gains tax on our trading profits is because, under current UK tax law, spread betting falls under the convenient tax bracket of “gambling”.
However – it shouldn’t be treated as such when it comes to placing your trades.
The Reason
When you place a trade you should have a reason. “Because it’s gone up a lot today” is not really a reason as you might as well toss a coin. A proper reason for a trade could be something fundamental such as research you’ve carried out into news, company earnings, economic data or perhaps something technical like analysis of a chart.The Limit
Once in a trade you might want to consider an exit strategy to collect your profit. If you place a limit order to take profit 50 points away, this could be construed as an arbitrary number ‘plucked from the air’ but if your research dictates the market will rise by 42 points, you could put your limit order there – a more thought out approach. Remember, your research determined your entry point into the trade; the same research should determine your exit price for your limit order.The Stop-Loss
A similar logic applies to your stop-loss. Our system selects your stop-loss for you based on the funds available in your account. If your research shows the stop should be further away (or closer) than the stop loss selected by our system then remember you can change this level to the price at which you feel you should get out of your trade.Also see Spread Betting and Stop Losses.
The Funds
Account management is just as important. Try to avoid staking all of your trading resources on one trade. If it goes wrong you will not have resources for the next opportunity. With £1000 on your account, a more prudent account management approach would be to only stake a maximum of £100 on each position you enter. This gives you the chance to get a few trades wrong and still be able to continue trading.Remember, using the stop and limit order facilities within Tradefair Spreads, coupled with prudent account management techniques, will enable you to make the most of the chances afforded from financial spread betting for a successful trading career.
