After placing an order, you can never control your mind if you watch your running trades.
Also if you read news, I am sure you will again go back and interfere with your trades.
These two mistakes will tempt you to commit lot of other mistakes also.
Finally you will lose all your capital.
You have a point, but you can also have self-control. For example, in cryptos is where I read the most lately, but still, I have enough discipline to read news and hodl my positions even if I check my account quite often.
I just replied to this post in the beginner category. Why do you post everything double and why so many short posts?
I keep an eye on both my trades and the news. Its only a problem when you dont have a system you trust or still have many questions in your mind.
Solution: Become familiar with your styles worst case scenario and stop procrastinating and do the math for the remaining questions and cloudiness in your mind. Master this and you wont be afraid to look at your workspace while in trades.
Before placing a trade based on technical analysis, we may consider high impact news event. If there is a high impact news event coming on the way, we may skip taking an entry on that chart. Once an entry is triggered, we should not keep eyeing on the chart. It would make us take wrong decision.
