Even experience doesn't stop a trader from losing that's the more reason why you shouldn't trade while on the move because you will feel distracted along the line and you may make mistakes that will make you to encounter losses. But if you think your experience can make you to trade at anywhere without minding the risk involved then you can trade anywhere you like, personally I can only trade in a calm and comfortable place and that has got to be when I'm t home.
It's not all about experience if you don't take the loss, how you learn it's always important for everyone trading is all about give and take but from here sometime you need to be quick and clever because while you are on good you have to take your exit
Trading is about profit and losses no doubt but experience trading over the years helps you to get better and trade smarter don't you think so? before becoming a good trader your losses are good lessons if you don't lose all the time it is not bad. Sometimes when you are making profit a little mistake can land you to inquiring losses so the best thing is to take a break when you noticed that, continue after a while if you think the losses are getting out of hand you can automatically stop trading for the day.
