I have a question(worry) that i cant find an answer for. I will have to live through I guess, but meanwhile I wanted to ask if other traders had any similar experience and what happened. I am an independent trader( daytrader) with 20 plus years experience in stock trading. I wrote an algo..maybe 15 years ago..and has been consistently profitable. The results were not great, but helped me pay the bills. After the Pandemic hit, something happened..it stopped being profitable. I understand that we are living in extraordinairy times, but i am wondering if there are any other traders out there..who have models with consistent positive returns for a long time..and then stopped working. WHen do you decide..the model is done..can it come back? Because it had such a long run..i am not willing to give up on it yet, but one has to pull the plug at one point.. ANy thoughts, experiences are welcome..
