On demo, a loss is just a number on a screen. With a funded account, the drawdown limit creates real psychological pressure. The strategy may stay exactly the same, but your decision-making can change completely. How did your trading change once real restrictions were involved?
The physiology
demo accounts and actual funded accounts are night and day, and that drawdown limit is where the real pressure kicks in. once u got real cash and strict rules hanging over u, it’s proper easy to crack under the pressure and trip up. that’s why getting into the habit of using something like a margin calc or max lot calc beforehand to check ur numbers is dead important for keeping u out of trouble.
