with only one technique we can achieve maximum profit as long as we want to explore and explore from the technique itself, personally I usually combine it with several techniques as filtering or reference when we want to enter and the indicator or market detector tends to where the trend is, if we try to hone it, we continue to test it continuously, surely we will understand the character and shortcomings of the technique. All we have to do is add it and polish it with self-discipline and good management. I think one technique can produce big gains.
