...This time when you are not trading with stop loss, take for example your computer become faulty when you are in a volatile trade without stop lose? This you can lose all that would have been protected by stop loss...
Every trader currently has many different gadgets, thanks to which, in case of failure of one of them, you can continue to track the price change in the market. The only case when you really need to set a stop loss is when you are resting and cannot control the process of closing an order manually.
Trading without a Stop Loss is the testimony of a lacking trading system. And I think using Stop Loss prevents you from adding to your losses and being emotionally attached to a trade.
