Most of the investors I've met who make use of foreign exchange expert advisors, have one particular issue. They crave for the expert advisor to produce amazing things, and I actually do not really fault them; that's why they purchased them. There's a single problem though, expert advisors should be calibrated on occasion. This info escapes a number of people. For those who carry out this suggestion, it will be possible to generate revenue through using even absolutely free expert advisors, downloaded from the meta-trader web-site. Straightforward, correct?
"But just how do we adjust our expert advisor?", you ask. Oh well, you'll need time, to be patient, a trial account to evaluate your strategy well before it will go live, as well as some basic logic before you decide to do your actual testing.
To make an outstanding test which establishes the actual real value of your robot, whichever the end result is going to be, (if it's a very good expert advisor it should make you money, if it's an awful one you can toss it into the can and save money rather than losing them to the forex broker), you should have tick data. Tick data is the tiniest, most detailed bit of price data. You absolutely need gigabytes of these. You can actually download them from your mt4 history center. The mt4 tick data will not be of such a high quality though, to be honest mt4 doesn't hold tick data, it downloads 5 min data and interpolates them to smaller bits. If you do some Google searching you can find one way to import realistic tick data for your mt4 strategy tester, which can make your own tests more precise.
Once you get the tick data, either from mt4, or perhaps from any place else you'll want to put your expert advisor to the test. Rather than letting you know the way to do it right, I am going to advise you just what exactly to not do and the reason why. Never request the strategy tester to test for virtually every possible combination for profit in all of your candlestick data. If you do this, you will discover suitable settings for just one huge junk of time, and you really don't desire that, you ought to look for data about a number of market scenarios. Have a shot at forward and backwards testing. Modify time periods, test for a year or so, and next for a couple of days, test for several months back and then a few months ahead. Shuffling candlesticks, will enable you to test your expert advisor with every possible, or very unlikely scenario, which is without a doubt what you look for. You ought to stress the bot.
At this point once you exhausted it and the expert advisor comes on top upon 70% of the cases and also the results are reasonable for your actual account balance, then test drive it using a trial account for one to 3 months. Observe how it behaves within your broker, in case you have decided on a broker that is located in Italy and you stay in America, then you certainly may experience some lag, you must observe how your expert advisor will get affected by that lag. The demo is not going to prepare you for the order price slippages of your brokerage service, that is one thing you'll solely figure out fx trading on a live account. Brokers usually tend to play with numbers as soon as the volatility is increased, just like any time news come out. Whenever that occurs the price you want to open on, will not be the one it will basically open. Keep clear of brokers which play these types of stunts.
Therefore, recapping this simple introduction to optimization,
Happy testing!

Therefore, recapping this simple introduction to optimization,
- You ought to optimize your expert advisor. Expert advisors do not usually get the job done directly out of the box.
- You want a massive amount of tick data for your simulation to get accurate. For near perfect results look for tick data, searching Google, and transfer them to your platform.
- Generate a large amount and various trading scenarios, test out your current expert advisor upon several time-frames, a number of currencies (if the expert advisor supports them) and most importantly upon a number of time ranges: different months, weeks, a few days, earlier years, etc.
- One last test needs to be performed on a trial account.
Happy testing!
