Can an EA automatically enter your risk per trade?

I have a "set & forget" EA that trades 12 currency pairs and generally makes 20 - 25 trades per week (4 hr timeframe). I would like to risk 2% (of my account) per trade - and eventually trade 3% or more per trade. However, my problem is this: I am often away from my computer when my EA enters a trade. Therefore, I am often not able to trade 2% on each of my trades ... due to the fact that I am not there at my computer to enter the necessary amount. SO, can someone tell me if it is possible for an EA to calculate and automatically enter trades of 2% (or whatever percentage I choose) of my trading account? Is there such an EA or program out there that will do this?

How do others here with an EA handle the problem of your EA entering 2% (or whatever percent) per trade of your trading account when you are away from your computer? Is there a way for my EA to automatically enter my risk of 2% per trade?

Many EAs use dynamic lot sizing to do exactly what you want.
You might need to contact the author of your "set & forget" EA and get him to modify it

RedLineFred, thank you for the reply.

My next question to you or anyone else here:

Is it possible to buy 1.6 lots ... 1.7 lots ... 1.8 lots? In other words, is it possible to buy a lot that isn't a whole number? Or does the forex industry only allow us to buy exactly "1" lot ... "2" lots ... "30" lots ... "50" lots ... etc.?
