I think if a particular strategy is not working again them I believe you should change it, maybe due to current market situation that's why your strategy is no more functional
True. His trading strategy doesn't work well anymore. Not sure what his trading strategy is, but if it is no longer effective then should be changed. The current market situation may be one of the reasons leading to the ineffectiveness of a particular trading strategy. I recently changes my trading strategy and my goal in trading. Now, I set lower profits and only holding 1-2 days after I bought a coin.
