First we should define who a good trader is. A good trader isn't someone who doesn't record losses, besides there is no trader who record loss. A good trader is one who knows when to pause and re-evaluate trading strategies which brings us back to the question. To become a good trader you need to be;

• Patient enough to wait for a market you understand before you risk it.
• Intelligent enough to know when to avoid the market
• Conscious enough to know when to exit a trade
• Knowledgeable enough to always update what every strategy being used
• Wise enough to always confirm every market setup including that which are gotten from bots
