Hi. I am looking for what you guys think is a reasonable monthly return (in points) for an intraday strategy for the ES per single contract. Thanks
Intraday trading will kill you, how fast or how slow it depends on how much leverage you use but kill you it will. My suggestion is to stick to the daily chart and use proper leverage. Usually futures are not the best instrument. You probably better off with ETFs unless your capital is ample then you can use futures but this is the exception and not the rule as in my experience I have better luck not using fixed stops. I'm not saying profitable daytrading is not possible but it's the hardest style to master.
the question itself is a bit silly since how can someone predict how much you can make without knowing anying about your strategy or its historical performance? Based on the very limited information provided, the most likely expected return will be a small negative number, since most day-traders lose money.
