I'm wondering at what point do you decide that your system is not just going through a bad stretch, but actually needs refining? I purchased a swing-trading indicator that combines MACD and a Currency Strength Meter and looks for confluence along D1/H4 then prints entry signals on the H1. I've been using a 1:1 R/R and the first 6 weeks I averaged a 65% win rate, which I was quite happy with. The past few weeks have been awful though and have only managed to win 37% of my last 30 trades. Is this a moment in time when I should maybe be looking for an additional tool in order to try and filter out losing setups? The author of the indicator insists that it is a stand-alone indicator, but I am having my doubts... Thoughts?
