I think it's normal for every trader to use stop loss in every trade because you can't always be right and also the market can decide to play around and hit your stop or change direction totally. So it's a must to use stop loss. Anyone not using stop loss is merely gambling.
I don't really think you are right, I know is really good to use stop lose but is not mandatory, I can enter a trade and I won't use stop lose, using stop lose is just a choice because not everybody really like using stop loss and they always make their money, it those not mean they are gamblers or they are bad traders, I believe using of stop loss is just a choice, I know lot's of traders that don't use stop loss even during bear market and they still trade successfully.
It's true that the stop-loss feature is not mandatory for us to use, depending on the results of the analysis and also the market situation.
I also made several trades without using the stop-loss feature and managed to make a satisfactory profit. Because the stop-loss feature must be
used at the right time, it doesn't mean we don't use the stop-loss feature like a gambler. That's the importance of trading courses, so that we can
learn many things, and know how to use the stop-loss feature well. In my opinion, sometimes too much use of the stop-loss feature can reduce
the profit we generate. So the use of the stop-loss feature must be wise.
