Well with some systems on C2 (like Bottoms Up) its pretty realistic since it only does EOD signals and instead of doing market orders, enters limit orders above the current price to limit slippage.
If you do have multiple entries, it can be cumbersome to post, luckily for me, I only do 1-4 trades usually max for the day, so it only takes me about 2 minutes as far as entering my trades go...
Collective2 is a nice 3rd party site that monitors a systems performance.. it has its issues.. but seems to be the best out there that i can see..
here is a link to my system..
