Well since my theory of Infinite Gamma does not exist, they sleep soundly better than a baby. LOL It's naked calls that should disturb the traders' sleep a bit because that's when the Infinite Gamma theory can really kick in to push the price up and also your losses to oblivion.
To sleep well, do not carry over your trades to the next day. This is what I like about intraday trading, when you close all your trades during the day and do not worry about what can happen at night or when the market opens the next business day (for example, a large gap can also occur). Also, you do not bear the costs of negative swaps. Therefore, it is more important for me that my broker fxopen continues to provide minimal spreads and instant execution, which is very important when trading intraday and quickly withdraws profits. Therefore, I sleep well at night)).
