practice is important and for that demo is a good choice , but i dont like this, i always try to maintain live account with minor balance . its supportive to acquire live knowledge and experience.
One common mistake is letting emotions drive trading decisions, especially fear or greed. I handle this by setting strict risk management rules, sticking to a plan, and reviewing trades objectively to learn from mistakes and avoid future errors.
My biggest mistake was overtrading entering too many positions out of FOMO. Now, I stick to my strategy, set strict risk limits, and wait for high-probability setups. Journaling trades also helps me stay disciplined. What works for you?
