As far as risk goes, the way I understand it, it is important to be consistent. What you do is risk the same amount of your capital on each trade. That way you can see if your system is profitable, and don't go broke while doing it. You can set up an Excel sheet to calculate the number of shares to buy on each trade. The only input it needs is the purchase price and the stop-loss price. Try this in Excel
In cell A3 put the formula (4000*0.005)/(A1-A2)
The 4000 stands for your trading capital. The 0.005 means that you will risk 1/2% of your capital per trade. Whatever you do, once you decide on your risk, 0.005 in this case, don't change it.
All you need to do then is to enter the price/share you paid for the stock in cell A1 and your stop-loss price in cell A2.
An example would be if your trading system told you to buy a stock at $30.45/share and to dump it if the price falls to $29.62. You put $30.45 in cell A1 and $29.62 in cell A2 and the formula in cell A3 will tell you to buy 24 shares.
(4000*0.005)/(30.45-29.62)= 24
On the next trade your system tells you to buy a stock for $14.52 and dump it if the price falls to $14.15. (4000*0.005)/(14.52-14.15)= 54
The beauty of this is that no matter where your trading system decides to set your stops the risk is always the same, 1/2% of your trading capital. So, besides trading fees, you can test a system and have ten losses in a row, and in this case you would only loose 5% of your trading capital.
Remember, stops are determined by the trade (they don't have anything to do with how much money you have or how much your willing to risk).
If you use this method to keep your risk the same on every trade, and use the same trading system to set your parameters for every trade (purchase price, stop-loss price, sell price), then you will have a setup that will test the validity of your trading system. If you keep changing your trading system and keep changing your risk/trade then you'll end up with a mess.
