How to Test Forex Systems
Anybody who has been round the forex market for over two mins knows that you always need to test foreign exchange systems before you go live with them. Even if the system includes guarantees, even if you got it from a top trader who makes millions with it, you have got to know that it’ll work for you.
So why do systems such as Forex Twister work for some folks and not others? Many folks basically find this quite difficult to believe. They imagine there is one perfect system out there that fits everybody and could make us all into millionaires if only we knew how to get a hold of it. But that idea is a total fantasy.
There are plenty of reasons why a system might suit some people and not others. It could involve some skill like translating a complex mixture of indicators that some folks will handle with no trouble while others cannot get their heads around it regardless of how hard they try. It may be to do with risk : the system could involve going to a quantity of risk which would be way outside some peoples’s comfort sectors, leading them to either subvert the system or make mistakes thanks to the level of stress.
So you must test and you can do this in more than one way. The best choice is to perform at least two types of testing which you can do at the same time.
First you may use backtesting. Here you take your system and figure out on paper how well it might have done on the recent historical market, i.e. The last half a year or whatever period you select. This doesn’t take too long as you can quickly scroll thru historical charts looking for the signals that would have led you to make a trade if you had been operating your system live at that time.
Backtesting should give you an idea of whether a system has potential. Naturally the market is not going to repeat in precisely the same way so you do need to take into account the indisputable fact that you might have struck fortunate or unlucky and picked a point in time when the system performed unusually well or badly.
For that reason, it’s best to backtest over the longest possible time and maybe split your tests so that rather than testing, as an example, one whole year when the market should have been especially robust or feeble, take the first quarter of year 1, quarter two of year 2, etc so that you test one 3-month period from each year of 4 years. This gives you a good period spread without requiring you to cover four whole years.
The second way to test forex systems is in a demo account. Here you are working with the live market but not using real money. This technique is slower because you have got to wait for your signals to come up for real . On the other hand, it emulates real live trading techniques with the possibility of slippage and other things which are not gong to show up in back testing.
Remember that you can test many systems at the same time in a demo account, provided you keep separate records of their performance. Or you can use many demo accounts. In this fashion you have a better likelihood of ending up with 1 profitable system at the end of your period of testing.
Foreign exchange demo accounts also have the edge that you are developing your live trading talents and familiarity with a software platform and charting service at the same time as you are running your tests. This gives you solid real time training to prepare you at present when you go live with real cash. Most forex brokers will provide free demo accounts which you may use to check foreign exchange systems.
