@ Andi, interesting to see that you are doing the same too. I’m using several logical groups both in the opening and closing conditions for some strategies. The only thing to note is that the EAs become too large and if you place them (like I usually do) on several currency pairs and multi timeframes then you will require a premium VPS to handle the load on MT4.
Simple EAs often work, I only use the complex ones to achieve specific objectives.
