Optimizing ForeXecutor Scripts**

The first thing to consider in optimizing a script is time frame of the test. I usually o for a year’s worth of data. In the current climate, we see three different types of markets. A ranging market, a strongly trending market and very choppy market are all seen within the last year. This allows us to see how the script will react to a wide

Range of conditions. For today’s example I will be optimizing the Points Grabber for USDJPY.
Once you have the data loaded and have attached the script, pull an Intllireport. Fortunately, previous work has benefited us already and we start with good numbers.**

This will not preclude me from going through the same steps that I initially did though. First, work with the Entry’s. In the points Grabber we have only 3 options to work with in creating the Buy/Sell Zones, which are the settings for the Bollinger Band. Simply begin changing the numbers to see if you come up with more or less trades. Remember that we are trying to improve on the above numbers.
After moving the numbers around for ten minutes, simply by trial and error, I came up with the following results. Are these results really better than the previous results? Let’s examine them.**

Ten additional trades produced 270 more points, which would result in only 225 (average spread of 4.5 points) additional points after spread. Our accuracy dropped by 3.81%, I try to stay above 70%, that’s just my trading threshold. The nice thing is that the draw down fell by 18 points. I am going to keep this setting and move on to the exits and see if I can’t grab a few more points on the way out the door. The first settings I will look at are the hard profit targets.**
WOW, after first finding that the hard target didn’t have much give in them I moved on the soft stop loss exits and gave the trade a bit more breathing room. The following results are clearly better.**

Now I’ll just start at the beginning again and see if the entry’s can be optimized against better exits. After repeating the same process for less than an hour here are the results of my back test. **

These results a very different. The big number that stands out to me is the 90 accuracy.** This would allow you to apply a more risky strategy of stacking or pyramiding. The final gain in points is 904 after spread, over the first series. Now you want to get more data in different market conditions for the pair and keep going until you find five to six hundred trades that produce the results you want. Those final results will most likely be different than these but in this you have an excellent starting point. In the next post I will address the danger of curve fitting and how to address that.**
