You are very right about what you posted, most traders do not have the money but they are trading with the little amount of money that they have and they become impatient and lose all the money continuously, they use high leverage and lose. I totally agree with you.
But for those that have $100000 to trade, they suppose to be making money than $100 daily even if they are patience. But they should not use leverage and they should not trade with the money at once.
Using leverage is not all the time the key to increase trading returns. In fact, it could pave way for bigger losses if you aren’t skillful with your trades. I don’t encourage using that, it’s still safer to trade on what you can afford to lose.
However, for those who are trading at a huge capital like $100k, still profits aren’t guaranteed in the end. But if they actually know what they’re doing, and they are good in exercising proper risk management, their trades will never fail them but may give them excellent profits then.
If they know what they are doing it can be an advantage having such decent amount for your investment, they can simply work with market movement and with skills and knowledge that they possess they can ride with the trend and take the profits that they can have, though still depends on how you deal with your understanding and how you will set your limits in terms of risk managements.
