Why not change your strategy if it doesn't work for you for quite times? maybe you need to re evaluate what happen and what mistake did you do then change your strategy so that you can get better trades on next time around and also strategy will never work if you don't have discipline also don't have any set exit plan so better learn that two before concluding things since for sure you will end up earning good numbers once you do a good trades.
The highlighted line above was right and I tend to agree, why do you keep using your strategy if you keep losing on it. Continuous losing isn't good at all, you might take a break and do your assignment of researching a good and new strategy that you can use and observe how effective it is, sometimes making a trial and error makes it worth it.
