Daily Delta+ Bollinger Bands for Following Trend

I am testing my indicator on on usdcad as I am trying to find alternative ways to invest. I have posted the hypothetical gains pf past performance and will be taking a small short position in testing this trade idea. I however will be using a trailing stop to lock in gains throughout the process. Based on my indicator, usdcad should be breaking out soon maybe in a few weeks with usdcad continuing the downtrend.
