Keltner strategy sell on eurnzd

My Keltner channel strategy
This is a mechanical strategy
I await a close outside of the outer bands
Then I await a pullback to the MA
If then PA closes on the same side of the outer band I've got an entry.
Pending order placed at H/L. GTC 1 unit of current timeframe.
SL at latest swing high/low
2 Rvr
Breakeven at 1 R.

Current statistical edge (will be updated as I test more instruments)
19% of orders doesn't get filled
24% results in breakeven
28% are winners
27% are losers

Keltner channel settings:
Length: 20
Multiplier: 2,5
Source: close
Not exponential
Bands style: true range
