Learning to be a disciplined trader

I have learned my lesson in the past few years to understand the importance of being a disciplined trader. The performance of my account gets better (20%+ return) after some successful tradings based on my own strategy this year. Still ways to go but I'm glad that things are moving in the right direction.

The top 5 tickers on my P/L list are:

BNKU, SABR, TQQQ, MOS, QYLD

Most losses of my account were due to lack of stop loss, which I believe many people have encountered when they just started trading. Should have set that up to mitigate your loss.
