In general, it is a good idea to use stop-loss orders
But you shouldn't use them blatantly and thoughtlessly. To put it differently, you shouldn't force yourself to use them just because it is the right thing to do.
Sorry dude, who told you it's the right thing to do? I trade handsfree without a stop loss. The key thing in trading is money management (MM). Make sure your lotsize won't overwhelm your capital while trading, and don't go in all as seen any trade as infallible, especially forex trading.
