Well, I do agree that if at the point of trading, one is experiencing that kind of fear and anxiety, best decision to make is to take a break. Fear can lead to losses, it can lead to making wrong calls in the market, it has a big disadvantage on the trader. So, when one is experiencing a sudden fear, they should not trade at that point, until they have killed that fear and are in the right frame of mind.
i losses in many trades for my fear and panic, i agree with you, if traders started trade with fear then there are high chances to make wrong decision, i feel it when i faced such issues, and happened with me for a lot of times, this is good point out we should take a break when feel fear in trade.
I think that only shows that we rushed to enter the trading scene and we lacked of briefing if what are the important points to know on certain situations. One of it is to just staying calm on a highly volatile market or if the market is only moving on one direction and that is on the low side. Some skilled traders can still navigate on them successfully, that is because they don't panic and they know more.
If we are fearful, that also makes us to not panic or we will only pause for a while and observe how things go first. That is okay. It is still be better to brave and confident with our decisions though because we are knowledgeable, so we need to taught it to our selves.
