This has been done. No need to run an EA for 30 days just use the strat tester. And to be accurate you will have to make sure that the random trades in your data set have the same number of long and short trades. If they do not then any long term trend in the market will skew your results. I would have your test EA open a long and a short both at the same time at a random time.
You will not be surprised with your results a data set with the TP twice as far from entry as the SL will have the SL hit a little over 2 times as often. I say a little more then twice as often because of the spread. The effect of spread will lessened if the spread is a smaller percentage of the distance to the stops. The conclusion I have drawn from my testing is actually how small your edge needs to be to make money trading.
Do the testing your self to see what I mean. Also pay attention to how you will change the affect the spread has by changing the size of the stops.

why do it with forex prices. Why not do it with a random number generator in excel. That way you can ensure that your data set although pseudorandom is as random as you can reasonably get.
Probably because subconsiously you think and hope that prices are not random so that you can make some profit at this but intellectually you think that they are so you are trying to resolve that conflict.
Here are some tables concerning risk / reward ratios that I find very interesting.

With a risk/reward of 1:1 any win ratio 50% or less is garunteed to blow your account.

Absolutely not. But that doesn’t mean it’s easy. 
hmm that’s too emphatic… I would say it is not random but it is very chaotic

If you use random entries then I think your results will be nearly random. As Shr1k says, a longterm trend will skew your resluts. I once downloaded a year of price data and tested random entries and that’s exactly what I found. At the end I should have been break even minus the spread cost, which were considerable. It wasn’t break even though and looking at a chart over that time period there was an obvious trend.

Somehow I don’t get what you’re trying to do.
Of course it's better to make 2 times what you risk and even better to make 3 times. The more you make, the better off you are.delete post
Yes, but you seem to be trying to make it random. To see if 1:2 is better than 1:1 you should be testing some non random part of the market shouldn’t you? like program the ea to some strategy like a breakout strategy for example. The more you make the test random the closer the results will be to a profit / loss of zero.

i don`t think you understand it the right way
if it is about random entries we may consider a study about what you are talking about
the entry setup should not be random at all.
the more solid entry setup you have the more wins you will get.
now let us suppouse that we have a good entry setup that give us a 60% of success rate
then we do 100 trade with risk reward ratio of 1:1
and another 100 trade with a risk reward ratio of 1:2
it is clear that the result in real money and pips will be much greater on the second 100 trade
the risk reward ratio is simply made to follow the rule:
cut your losses fast and let your wins run
without a good entry setup you are gambling not trading

I dont think the concept is confusing people but more the point. R:R in of itself means nothing. Like trading a divergence byitsleft means nothing. We already know this. But when R:R is combined with a profitable strategy thats where it becomes effective .

Not true Banker…
This is a good topic, and I’m keen to watch from the sidelines.
I just don’t want to get too involved in a debate that can never be won.
But I’d like to see your results, even though it wont change my mind.
My best months were when I got a risk/reward of 1:1.5 or even less, but I’ll probably get flamed for even saying that.
People get religious about certain things here, and this is one of them.
