But at a more basic level each spread betting client should follow the same fundamental rules to ensure that your trading activity addresses your specific trading goals. Apply the same rigour to choosing your spread betting provider as you do to choosing which markets to trade.

This is one of your most important trading decisions.

And be prepared to switch providers if you are no longer getting the service you need. Draw up a checklist of your requirements, then choose the spread betting firm that best fits your criteria. Do you need personal customer service. Do you want free trading tools to support your trading.

Is a reliable platform your number one priority. Spread betting lets you maximise the return on your investment capital, but it will equally maximise your risk. Stop-loss orders can help you to control your risk on individual positions and across your spread betting portfolio, without restricting your profit potential, but remember that stop-losses are not guaranteed and may be subject to slippage and market gaps.

You might also consider staggering your entry points. That is, when you have a signal to trade, instead of taking your full exposure at one entry point, you could create a series of smaller positions as the market (hopefully) moves in your favour. This way, if the predicted price move fails to occur, you are not as heavily exposed.

And as (with InterTrader) there is no minimum charge per trade, there is no drawback to taking multiple positions. Your trading plan is your best judgement of how you can achieve your trading goals.

Learning to control your emotions is a key part of spread betting, as you develop a robust trading psychology. Learn from your losses. Each one contains a lesson. As part of your trading plan you should have a strategy for coping with the potential downside, defining your maximum acceptable loss per trade and across your spread betting portfolio. Most traders will use some combination of technical analysis, fundamental analysis and analysis of the effects of news events on the markets.

In order to do this you will need access to historic price data, charting software, financial statements, macroeconomic data and news feeds. With InterTrader you get free unlimited use of IT-Finance advanced trading charts, expert technical and fundamental analysis, live market news and squawk, plus trading signals on the most popular spread betting markets.

No doubt you will develop your preferred methods for picking trades, but remember to build them into a systematic process, part of your daily trading routine. Spread betting makes demands on your time. Each aspect of your trading process is critical.

To make best use of your time, focus your spread betting on markets you understand well. You can also save time by setting up orders to implement your trading plan, and using mobile trading platforms to trade on the move.

The best way to develop your understanding of spread betting is by placing trades, and with a demo account you can run virtual spread bets without taking on any risk. Spread betting and CFD trading are leveraged products and as such carry a high level of risk to your capital which can result in losses greater than your initial deposit.
