If you trade 10 months per year, with a fixed money management method, and you earn 1k per day, you would make 200k per year on 50k..
Also, the more leverage you will use and the more difficult and stressful your trading will become.
Perhaps lowering your expectation as much as possible at first, with a very gradual increase of position size, could be easier.
You could also find that you will reach a plateau, psychologic or strategic, limiting your own possibilities to reach 1k per day, when increasing position size.
And to answer your questions, I will tell you how it would be possible for me after few years of trading financial and index futures:
Fortunately for me, I don't have to make 1k out of 50k, every day. Some days I will make 3k and some other days... Not so well. My 1st goal is to be positive every week.
Consistency is complex. Self imposed 1k per day would bring to much stress. I do have goals, more like maximum loss per day and my own daily max profit I will stop trading (before I feel the best trader on the planet and lose everything back...)
Sure, but for how long? Being able to grow very slowly 50 to 100k would bring a lot of self confidence and make you aware of your capabilities.
I tried to learn to play guitar, not so good.
On the positive note (...), it didn't took me 10 years to profit from the markets, as soon as I understood few principles (that works for me at least).
So, is it possible? Yes I think so but for so very few people. And don't take that the wrong way, but I don't believe this is a reasonable goal, especially if you need your 50k and if you don't have a lot of experience.
Happy trades!
