So, let’s continue with our preparations for the upcoming ATC 2011. I’ve decided to start with the very beginning and outline the most important components of a successful MetaTrader EA. Please note that while some of the properties described below are good only for participation in ATC, others can be used as a guidance in your usual expert advisor development.
Main Idea. To create a good EA for ATC, you need to have the main idea for it. Whether it will be some existing MetaTrader expert advisor or something completely new, depends on you. Price action, moving averages, chart patterns, some exotic indicators, neural networks — they all can be a part of this main idea, the principle of your EA. I have yet to choose the main idea of my ATC EA and this will be the topic of my next post in RTATC2011 series.
General Optimization. After you have coded an EA around your main idea, it’s time to optimize it. But one should be careful with optimization. Overoptimization will lead only to losses during the championship. The best strategy is to optimize your input parameters, so that the EA works profitably on several different time periods. After that, it’s a good idea to find the optimal input parameters for each of the currency pair that will be traded by this EA (more on
ATC Money Management. It’s obvious that only the EAs with an aggressive money management strategy can win in ATC. The EA should risk a lot to win a lot. Reverse Martingale strategy will work best here — you increase your position size when you win and you reduce it when you lose. Some traders set the maximum possible position size from the very beginning of the tournament. In my opinion, it is too risky. I prefer my EA to be able to lose about 5–10 positions in a row (depending on its win/loss ratio) with the starting volume before going completely bankrupt. Additionally, one should be aware that the maximum position size for a given currency pair is 15 lots, while the maximum size of one order is only 5 lots. So a special system of orders should be implemented to open huge positions when the account balance reaches a point, where such sizes are sustainable.
Fast Execution. Needless to say that if your EA is very good but it requires more than 20 seconds to place one order, it won’t be successful in ATC. More than that, the contest jury may decide that it’s a too heavy burden on the ATC demo servers and won’t approve such an EA for participation. That’s why too complex expert advisors isn’t the best choice for this championship. It’s better to try implementing something light and fast but still effective.
Dealing with Trading Conditions. As with all the previous ATC contests, in ATC 2011, the trading conditions will be modeled with all the realism of the actual MetaTrader brokers — you’ll get requotes, slippages, order delays and other unpleasant obstacles. The EA you develop, should comply with this conditions and behave properly. That’s not too difficult to implement and it will be discussed in my later posts.
