How will you even encounter a loss if you already have a good strategy in place? A good strategy always have an exit plan that makes sure your losses are at a minimum, what I think someone should have instead of emotional control when it comes to trading is discipline, discipline encompasses even that part so having a discipline means you have control over more fundamental things granted you have a good trading strategy in place.
@Latviand, Although everyone has their own trading strategy, the combination of all the relevant trading tools, candle types, and use of indicators Every trader has their best indicators and strategies that they feel are able to help them understand the market direction better, which can still be labelled as trading strategies. A trader can also decide to only trade at night, in the afternoon, or in the morning because they believe that's the best time to make more successful trades. All those are strategies that one can derive for themselves. But with your strategy, if you allow emotion to take part in the trading decisions you make, then you will likely encounter more losses than you expected. although everyone is not the same. So if you point out facts, always know that everybody is not the same. One can be very good at something practically, but in theory, they may have poor performance, and sometimes vice versa.
