I get confused about what is your name. Sometimes you say Samuel, sometimes Smaul :)
All the EAs that are based on trend indicators are trend-following EAs.
You can find the trend indicators if you go to MetaTrader – Insert – Indicators – Trend. You have 7 indicators there which are known as trend indicators.
If you want to build an EA using any of these indicators just add it as a preset indicator. The Generator will find strategies for you using this indicator.
Now, the trend trading EA depends a lot on the rule of the indicator.
For example, if you use Moving Average, you have a few options:
If you use Moving Average rises for entry condition to buy, then yes, you have a trend trading EA.
But if you use the Moving Average changes its direction downwards then you will have in EA that opens a buy trend against the trend.
So when you runt he generator with preset indicators, just have a look at the entry rules and pick up the ones that are following the trend.
Of course, you can combine a few indicators which would be the better thing to do.
