How you make the split will depend on the amount you have to trade as well as your own attitude to risk. The more risk capital you have, the more you can divide it up. This in turn will give you more trading opportunities. Overall the aim is to keep losses small and manageable, so you still have enough risk capital to continue trading. Then you can relax and run your winners and look to lock in bigger profits. Doing this consistently over time is the key to successful trading. It will also help with another key part of your trading plan - developing clear instructions for position sizing in relation to the size of your account. Once you’ve decided on how much you’re willing to risk on each trade, you have to apply this limit every time you discover a trading opportunity. We’ll illustrate this point with an example:
Let’s say that you have trading capital of £5,000 and you decide that the maximum you’re prepared to risk per trade is £100, or 2%. Now, perhaps you have been following the UK 100 market - it’s trading around 7,355 and trending upwards. You want to buy the index but not at current levels. You study your charts, apply some technical analysis (see below) and identify a decent buying level around 7,320 while a good selling opportunity comes in around 7,400. The latter may be an area of resistance, marked by the inability of the index to break above this price. You now have the potential for a trade. You decide to put on a limit to ‘buy’ at 7,320 and then sell to take a profit at 7,400 – potentially an 80-point gain. You have already decided that you will risk no more than £100 on the trade, so you could simply put an order to buy £10 per point with a stop 10 points below for a risk of £100. But this takes no account of how the UK 100 may swing around even if the overall upward trend remains in place. In fact, in this example the chart suggests that the UK 100 could fall back to 7,300 where there is a major support level, and the upward trend would remain in place. You decide to put a stop in at 7,295 – 25 points below opening level. To make sure your risk is around £100, this would mean opening a trade of £4 per point, at the most. You may decide to be more cautious and limit it to £2 per point, hopefully keeping the potential loss to £50 (assuming no slippage).
Now you have a limit to buy £2 per point to open - 7,320
You have a limit to sell £2 per point to take a profit – 7,400
And you have a stop to sell £2 per point at 7,295 should the UK 100 move against you
You have decided to trade £2 per point, so your risk is around £50 with a profit target of £160
This gives you a risk : reward ratio of around 1 : 3.
So, you have used risk and money management together with some technical analysis to plan a trade.
Bear in mind, that while in this example you’re risking £50 of your £5,000 risk capital (or 1%), you will need to deposit £732 (7,320 x £2 x 5%) as initial margin on the position. Consequently, there will be a limit on the number of trades you could have open at any one time even with a healthy £5,000 of risk capital in your account.
