Optimization Practices Revealed This week, we'd like to discuss the topic of optimization as well as some of the do's and dont's when optimizing. The below practices refer to optimizing automated trading strategies with a focus on foreign exchange. While the below practices can be applied to any automated system, the foreign exchange market and MetaTrader 4 is used in all of our examples. In summary, optimization can be defined as a process that automatically finds the most profitable inputs for a forex robot. For example, forex robots may have certain take profit and stop loss parameters (i.e. TP = 50 & SL = 15). Using the MetaTrader 4 platform, these parameters can be optimized to reveal which values for take profit and stop Loss would yield the most profit. When running an optimization, it's important to keep in mind that the top settings found by optimization aren't always the best settings. Think about it, if you run an optimization of take profit, stop loss, and moving average value for all of 2009, the settings you find are the best settings for 2009! Markets are always changing and just because you have the top settings for last week, last month, or last year, doesn't mean they will continue to perform well on live market data. What is optimization good for then? Great question! Optimization is a great starting point to reveal some settings that have worked well in the past and may continue to work well in the future. For example, let's pretend we ran an optimization of take profit and stop loss for 2009 and the top settings turned out to be TP = 100 & SL = 50. Now that we know what the top settings were for 2009, let's apply those settings to some market data outside of 2009; we could then run a simple back test using those settings on market data from 2008. This is called an out of sample back test because the data you're applying the strategy to is outside of the optimization sample. If you conducted a back test within 2009, it would obviously be a very good back test because that's the period the strategy was optimized on. After we find our top sample for 2009 and apply it to out of sample market data (2008), we can make better conclusions about our strategy. If the take profit and stop loss of 100 & 50 work wonders in 2008, great, we could really have something here! This tells us that even in different market conditions, these parameter values held up; pretty promising find! On the other hand, if the strategy crashes and burns when you apply it to different market data, that should tell you the settings you're using probably won't hold up. At this point, you would go back to the original 2009 optimization, find another pair of settings that worked well, and try them on 2008 (or any out of sample data). The process can be grueling but optimization serves as a great tool for traders who know how to use it. Below we're going to touch on additional topics within the realm of optimization. Over optimization This term is used consistently with "curve fitting". What happens is that when you over optimize settings for a particular strategy (optimize down to every tiny detail) the outcome is a remarkable back test for the optimization time frame. This produces a wonderful looking back test and a glorious equity curve. However, when you apply these parameters to a live account, the system almost always loses money. Essentially, you have fit the strategy to one set of market data, as we discussed, that is a big no-no. You need the set of parameters that is the most robust and trades well on a variety of market data. Walk Forward Optimization Walk Forward Optimization is considered the ideal form of optimization and although it is time consuming, it puts any forex robot to the ultimate test. Within walk forward optimization, you start by running an optimization for a certain time frame, as an example, let's take an optimization for all of 2008. After the optimization is completed, you take the most optimal settings and conduct a back test with them on data that follows the optimization window (2008). Because we optimized for 2008, we're going to take the top parameters and run a back test for the first four months of 2009 (we used the first four months because for the walk forward test, you are supposed to use a window one fourth the size of the optimization window). So after you test your strategy on the first four months of 2009, you can get an idea of how your system does on out of sample data, immediately following an optimization. If you're strategy does wonderful, that's a great start, the next step would be to walk the system forward and optimize for February of 2008 to January of 2009, and then conduct a back test for February of 2009 to May of 2009 and evaluate the out of sample trading. When you are finished, you look at how your strategy performed on the out of sample tests, if trading is strong, you can move on to live data testing, if its weak, you should consider a different robot or possibly refining how you are using the parameters. No doubt the above process is lengthy and time consuming, that is why have formulated our own means of optimization called shop-timization. This methodology entails conducting an 18 month optimization on the most recent market data (January 2009 - June 2010) and then finding the top settings. Once you have the top 20-30 settings, you back test them all over a 10 year period (back to 2000) and see if there are settings that trade very well over 10 years. If you have a system that trades well over the past 10 years, that is something that shows great promise and you are probably ready for live demo testing. Our methodology with shop-timization is that the most recent technology, accumulated knowledge, and price action is discounted into the most recent market data. So having an optimization on recent market data allows you to find the parameters that have held up in the present, and possibly all along (which is revealed through the 10 year back test). Give it a shot, it's not as hard as it seems. I just bought a robot, now what? If you've recently purchased a forex robot and want to test it for optimal settings, we recommend you start by looking at the external parameters of the robot. These are the items in the input section for the robot, meaning if you double click the robot in the navigator window and click the inputs tab, you will see the list of external parameters. These are the items that can be optimized; you should understand what they do before you begin an optimization. Most of the time, the details of the parameters are included in the manual for the forex robot, if they aren't, we recommend you contact the developer to help elaborate on what each parameter does. What you're really looking for are the settings that will yield the highest profit for a live account. To find these settings, we recommend you run an optimization of the last 18 months, so as of this writing, January 2009 through June 2010. When you have the top parameter sets, test them out over 10 years worth of data, so back to year 2000. If you find a pair of settings that have wonderful results, you are in business. A strategy that trades well over 10 years of data and therefore a variety of market conditions, may prove to be very profitable. So try it out! Start by running an 18 month back test and then applying the settings over a 10 year back test to see how they perform.

10 Easy Steps to Succeed in Your Online Classes
