    This must the the most hilarious post of 2020 :D you obviously new, but just get to your head, no one and I mean no one will post anywhere something that really makes money. One exception was SOES bandits, but they needed humans to pick MM pockets.

  2. Who said I was trying to become a "millionaire"? All I am trying to do is make 1-10% a day. Thats not difficult. Suppose you write a script that looks for a scalp trade where you risk 3 pips to make 9 pips. And lets say you can make this trade 10 times a day, 24 hours a day. With a lot size of 300K units, and a win rate of 50%, that would be a gross profit $2700 and a gross loss of $900. Net profit is $1500, or 15% per day. (account size is $10k.)

  3. Your right it is pretty funny. This is supposed to be a forum of "experts", yet you guys think that making a meager 1% a day is a scam, and don't know what leverage is. I bet I can find more intelligent content in baby pips for christ sake.

    I meant that a very profitable strategy was shown to strangers. SOES is the only one I know off

    The problem with leverage is not the money you make, it's the money you lose that very well can put you back below where you started. There is an optimal leverage for a given trade sequence (see Kelly criterion) and going beyond that is just going to reduce profits, ultimately below zero. Unless you have a very high Sharpe ratio, chances are you can't apply anywhere near the amount of leverage some brokers provide you with (usually without anything but generic warnings like "could lead to large losses").

    As for your opening post, there are some people that have achieved an annual return of 1100%+ some years (which is what you're effectively asking), but they're not doing it consistently, because it's immensely hard and in most cases requires unexploited alpha in the market, and/or it was just luck (for instance being long Tesla from March through this year.. nowhere near consistent 1% daily gains on that by the way).

    Finally, for a system that consistently returns a thousand percent a year, A) nobody will sell it on NinjaTrader or to retail, B) it will have limited scalability, C) the chance of discovering something like that in developed markets like in major US indices is incredibly slim.

  9. Look buddy I didn't ask you for how leverage works. This is the reason I am leaving this forum and deleting my account. That is a beginner level question, and it seems that you don't even have the correct answer for. It doesn't matter if you use leverage or not, your risk is determined by your stop loss. Leverage just reduces the minimum equity needed to make the trade. Leverage has nothing to do with gains or losses, as it has to due with the amount of money needed to initiate a trade. If my stop loss is 10 Pips, and I am trading 100K units, leverage or not my losses are exactly $100. Leverage is used if I don't have the necessary funds to fullfill the trade in its entirety. I can make that kind of trade with $3000 of margin. If I get stopped out, I am only losing $100, or 3%.

    I would appreciate if you didn't insult me with these beginner level answers to questions that I never asked. I asked specifically if anyone had any auto trader script they recommended. If you don't have anything valuable to say, than don't say anything. This forum is just a bunch of noobs. See ya.

    Since your words speak for themselves (they really do), I will just add:

    Not every broker offers guaranteed stops, and they come with additional costs due to the tail risk that needs to be eaten by the broker. Regular stops will be gapped past at times with potentially catastrophic results.

    People don't have autotrader scripts they recommend for reasons you should be able to infer from my post and others.

    You sound like you're in your 20s at most so I forgive your self-destructive sense of superiority which is common for males of that age.
