Yes, I think they do.
I've never taken any notice of them at all, myself.
There's absolutely nothing wrong with a profitable system of the kind you describe, with 1:1 R:R and a win-rate around two-thirds. It has a Profit Factor of 2.0, after all.
One of my own regular trade entry types has a R:R ratio of (just) below 1.
I know at least one successful, independent (ex-institutional) trader whose primary trading is exactly as you describe, with equal-size targets and stop-losses, and up to about a 70% win-rate.
Trading like this, with a lower R:R ratio than most people recommend has a couple of specific advantages, too: it makes for a much smoother equity-curve than all those other traders with the higher R:R ratios can ever dream of, and it makes your position-sizing particularly easy to work out, too.
You can adjust the settings of "when the day starts", if you want to use 24-hour timed charts. (I have no idea whether your method will work the same way, if you try it, of course ... so I'm "just saying".)
Nothing wrong with that either, in itself, but be aware that some of your trades, if you're looking at 8-hour bars/candles, may represent as much as 20 times the volume of others. (For example, the 8-hour bar that includes the 4-hour time-slot during the RTH of both Europe and the US will represent huge volume compared with the "dead of night" one representing a couple of dead hours and a bit of the Asian session.) You presumably need to take care over whether/how that's relevant to you, and if so, with which pairs? Again, I'm just mentioning it in case you weren't aware of how significant it can be, with some methods.
