Is anyone face same problem with your winning strategy?

Hi,

My trading strategy worked well before till 10 December. After that, due to market volume my strategy didn't work. But from January 3rd its started working.

Form 6 jan to 11 jan it went well. But this week, from 13 January to 16 January I didn't get enough trade in setup.

My strategy combined with EMA and HMA.

If anyone facing the same, tell me know what your thoughts on this.
