EAs use statistical data. I think that most of the EAs have the ability to perform on any pair. But recommended pairs are only most traded pairs, especially Majors. There are some EAs, available commercially, that restrict the pairs to 1 or 2.

I hope you understand that why some EAs say that it is best to use them with specific pairs.

Ironical's point is correct. I will explain it a bit further. You r normally given a chart settings manual with an EA. Time settings are also given. Some EAs work with 1 h settings, some with 15 mint etc. So if a currency pair is not traded much, it will obviously have not much trading data during that time period. It will effect the working of an EA. So EAs are made in accordance with the trading popularity of the pairs.

mmm. The basic purpose of EAs is profit making. So if EAs are designed to work with some pairs based on their trading volume, there is no objection as long as they make good profit.

Nowadays account management and signal services are becoming increasingly popular. People prefer to use account management and signal following. Most of the EAs available in market are either a complete failure or produce very low profits. Who would waste time and money to search a reliable EA. Websites like fxstat are already giving us autotrading services. It is better to use them instead of searching for an EA.

I think commecrially available EAs do not even know about how EAs work. They just know how to sell a thing which is known as product. So based on their words, you cannot say that an EA can only work for 1 or 2 pairs. You can optimize an EA according to your needs and currency.

I think this is a strategy of EA companies to attract people by saying "Best for Eur/usd" etc. Forex traders think that this company might have spent all resources for 1 pair and this EA will work best than other EAs that work for multiple pairs. So I think this is just a marketing strategy. Otherwise an EA work on statistical basis and can work for any currency with a little bit changes in settings.

If you talk about Some fake companies with excellent marketing strategies then your r right. There are many EA makers who have developed EAs to work on specific pairs and they perform very well. You can see on different forex forums about such people with their trading history. I think EAs are normally made to work on specific pairs. Because each pair has its own liquidity level.

hmmm. I have to agree with your logics. In my previous post I also mentioned that liquidity levels are a big factor in trading. Because high liquidity levels mean fast trending.

I have to disagree with you guys. That's true that every pair has its own preferences, but their liquidity makes no difference because it always depends on the BROKER.

Illiterate, High liquidity levels has nothing to do with trending not even fast trending. Trending is a fully another topic.

As you know by Liquidity we mean about the spreads, and how fast you can execute positions.

mmm... In my opinion liquidity of a pair highly effects the trend. Liquidity and spreads are related in another way.

For example if a pair or a commodity is highly liquid, its trade volume will obviously be high. High volume trading will effect the trend. So even low timeframe charts will show upwards and downwards trend. Whereas less liquid pairs or commodities cannot show fast upward and downward movements.

That is normally seen in forex trading.

Richde has a point. Liquidity is related to broker. But can you please explain how it is not related to trending. Maybe I am taking liquidity in another context or maybe you r thinking in another way.
