Learning About Back Testing Trading Systems

Wednesday, February 17th, 2010

After you`ve set your initial stop loss, chosen your method for calculating your trailing stop loss, and implemented all your money management rules, there is one last thing you should do; you should begin back testing your system.

With out back testing you will be headed in the right direction, but you won`t know what to expect from your system. Back testing will also give you the confidence to keep going when you begin to experience the doubt that every trader faces at some time.

Back testing your system is by utilizing the rules and conditions of the system to the stock`s historical market data. However, this is only possible if you`re trading a system that is entirely mechanical and does not require any human input to place the trades. How do you know whether or not your system is completely mechanical for back testing? Can you take down your trading plan, the set of rules and guidelines that you follow, and hand that over to someone else, who could then trade the same system and receive the same results as you would if they followed the system carefully?

If you can accomplish this, you have a mechanical system that is ready for back testing. If you can`t, you should look at implementing a completely mechanical system. Perhaps one of the hardest parts in trading any system is to have the confidence to stick with your system. In fact, a mechanical system almost forces you to make decisions that are in direct conflict with what your gut feeling might tell you to do.

Just remember, our gut feeling tells us we should hold on to losing stocks until they get to the break even point, and our gut feeling would tell us to sell shares as soon as we`re a little bit in profit. Obviously, a mechanical system goes against these human tendencies, and that is one of the reasons why it`s psychologically difficult to trade. However, back testing a mechanical system, will tell if you it your plan will work or not.

While back testing won’t tell you with 100% accuracy what the profitability of your system will be once you start trading it, it will give you a very good sense of what you can expect. All prices are driven by the same two factors, supply and demand, in the present and in the past. So, even though price movements are never going to be exactly the same, in your back testing you will see the patterns, and similar movements that show up over time. With back testing you can discover the how profitable you system is likely to be, and how often you are likely to have a loss rather than a profit.

When back testing your system over different market conditions, it can be reasonable to draw parallels as to the performance of your system historically to its performance trading it in real time. Knowing this, because of back testing, will make it much easier to stick with your system, and the profits you can realistically skyrocket.

What Affects Currency?

Sunday, February 14th, 2010

Many of you like investing in different kinds of investments. One type of investment that you may have is foreign exchange or foreign currency trading. Do you always win the game? Or are you losing money on that? You are not a sheep that simply follow what others do. You need to setup you own foundation on currencies before you can gain your money!

In fact, currency fluctuation can be affected by a number of factors. In the broadest sense, a country’s economic situation and its macroeconomics decisions have the greatest effect on its currency fluctuation. That is why you find the analysts are really familiar with such economical statistics, news and information. Common indices that you should be aware of include Gross National Product 9GNP), interest rates and consumer price index, etc. With the grasp of such information can help you make wise decisions in the forex trading market.

International profits significantly affect the currency trend. International profits are the net amount of income and expenses on foreign economic activities. Under normal circumstances, trade deficit indicates that the demand exceeds the supply for the foreign currency/trade/imports. Under the floating rate system, market demand and supply determine the currency fluctuation. A trade deficit can cause the depreciation of local currency while appreciation of foreign currency, vice versa.

Another point to look at will be the national income. When people’s income increase, they tend to be spending more or they are willing to spend more. As they spend more, this pushes the demand of local currency up. As mentioned before, with the increase in demand, the local currency appreciates.

Even though you see that people’s income is increasing, it does not necessarily mean that the local currency must appreciate. You have to understand the real factor that drives the increase in people’s income. For example, if the increase in income is driven by a series of government policies or demand, you may not see the appreciation of local currency. Why? Usually the government demand is so big that additional foreign imports are required. In this case, the demand on foreign imports or foreign currencies induces appreciations of foreign currencies.

Inflation rate is another fundamental factor that affects currency fluctuation. If a nation has over issued its currency which exceeds the demand in product purchasing, there will be inflation. Inflation decreases the purchasing power of the people and therefore leads to currency depreciation. In general sense, the local currency depreciates means the foreign currencies appreciate.

The main factors affecting currency fluctuation are basically covered here. There are still many other factors causing currency appreciation and depreciation. You should get yourself more well prepared before invest in forex!
