I think this strategy of mine uses a similar idea to your strategy but with a dynamic price filter for over and under at the same time.
Despite of, the connections to the backtests are lost by now, I think I still have it running quite smoothly. The Avg daily and Annualized Return may not look as impressive as if I would have run it with unlimited deals (aka -1). But if I compare the Total Profit after around a year with the still not available and only estimated calculated Max parallel costs then those bots have achieved around 100% or even more each.
