Your risk factor is the most important that can determine this. For instance if your risk factor is 1% per trade to gain 1% profit, then the total number of winning trades less your total number of losing trades will give your percentage turnover monthly. What I am saying in essence is that the answer to this question is relative to the trader involved. For me I can turn over 0.5% daily and this means that in a month I will have 10% return in my account on the average. % of profit from this market daily is not easy things for this trader have to more practice and i think i get 1% profit from this market daily because some times i get good profit but in some days i give loss also for this reason my profit % is low and i think this profit is quite enough for me.
