When is M5 a better primary than M1 for your costs?

When M5 beats M1 as primary — after costs

M1 feels precise; M5 often survives costs better. I switched primary to M5 on several names when my M1 journal showed lovely entries eaten by spread, noise stops, and the illusion of control. Precision that cannot clear round-trip cost is decoration.

Rule of thumb I use now:

• If average trade duration and stop distance on M1 cannot clear round-trip cost with room, promote M5 for bias and structure.
• M1 can remain the trigger only when spread is calm and the M5 story is already clear.
• Gold is a frequent special case either way — test with a cost log, do not assume from majors.

Timeframe pride is expensive. Let the R-cost decide hierarchy.

On which pairs did M5 become your primary because M1 could not clear costs cleanly?

I still glance at M1 for timing, but the permission to trade comes from M5 structure clearing cost math. Permission and timing are different jobs; conflating them was my old expensive habit.

EURUSD and GBPUSD both went to M5 primary for me. The rough test I use is round-trip cost as a share of the stop. On EURUSD raw, about 0.8 pips all-in against a typical 4-pip M1 stop is 20% before the trade does anything. On an M5 structure stop of 8 to 10 pips, it drops to single digits.

Anything above about 10 to 15% and the M1 entries have to be genuinely better, not just prettier, to make up for it. Mine weren't.
