Hold only one ETF.
Hold QLD when the signal is BUY.
Hold QID when the signal is SELL.

I downloaded closing prices for QLD and QID, and calculated the same gains Zeelotes posted:

3/7/2022                                       58.04  22.23

Either hold QLD or QID. For example,
buy QLD on Jan 5th at 82.75
sell QLD on Jan 12th at 84.09
gain was 1.63%
