Well, Mate. It will be depended on what broker you will use. Think we use Instaforex as our main broker, 8 standard lots Insta will cost about $8 each pips. Then it will be depended in pair and leverage you will use, assume you use 1:1000, in pair EU for 8 lots I think it will cost about $95.xx for minimal margin required (If you wanna get instant calculation, just use Insta's Forex Calculator at https://instaforex.com/forex_calculator.php). Thats only think from margin side, when you open a trade, you must think about its spread, for EU it is 3 so it will be -$24 floating once you hit a trade. And, when price move a pips, remember that it will cost/gain $8 each. So, I ll give to you for rest calculation. Hope I can help. Thank You!
