If have a balance of 1000$ i would give preference to capital safety as i would not want to lose it, so taking appropriate safety measures i would only go to earn on an average 10-15$ a day - bigger expecations brings in bigger risks too.if you set $ 1 per pips then you just need 50 pips per day and it means that you get $ 50 , it is good and safe for your trading and if you want to increase your earning then you can set the lots isze with the higher one, but be careful, increase the lot s then you just increase the risk too
