If a trading strategy brings you a good profit, then you should continue to use it.But you should understand that this will not last forever, and you should test new trading strategies in advance, and AI can help you with this.
I totally agree with you. Any trading strategy has failure times and even it is a very good trading strategy not only in theory or in words of mouth but in your own practice, you must be aware of this fact and also prepare for danger and risk of losing money with the strategy whenever it fails. It's not because of the trading strategy but by the market in most volatile and decisive times. Around such times, it's best if you see the risk, close your trading position to defend your trading capital as your most important task. Later when the storm gone, market decides a next direction, you can open a new trading position with that trading strategy and very likely it will work well for you.
Having 2-3 trading strategies to switch between is better than focusing on just one.
I tend to agree that it's wise to continue using a strategy while it's successful, but once it starts to fail, it's time to switch to another.
Once my trading strategy begins to falter, I will not continue using it because, for me, it simply won't work, even if I apply various improvements.
It depends on how many times you failed with that trading strategy and when. If you failed with it in squeeze time like I said above, it's likely not because of the strategy, but it's by your wrong decision to stay in the market in most dangerous times.
