Any thing can happen in forex market at any time. So for the safety of your funds, you should never trading without using a stop loss no matter what the conditions are.
I guess this is just some sort of excuses given by their regulators just to regain confidence from all those retail traders. Maybe I shouldn't describe them as trader because it includes farmers, security guard, salesperson etc that believe a lot from media. So shall I describe them as trader?
There are some good traders in China, but people in any country who jump into the stock market "because it can only go up" are best described as incipient liquidity providers.
Stop Loss is an easy way to manage funds, We can secure our amount from a big loss when we set stop loss at proper pips . We afford this much loss and no more risk is there in trading for us. I also try to use stop loss in trading .
I too think it's prudent to always use stop loss. That is, unless you're scalping and you're relying on manually closing your trades at any given time.
