Hi Rick

In reality the H12 is simply the timeframe I picked after initially trying the H1 after initially finding that the H1 didn't suit my requirements and I wanted a longer timeframe. The fact that I am only trading this timeframe atm is simply a reflection of the fact I am in my early stages as a fulltime trader and so haven't had enough time to test/develop models on other timeframes. So I haven't done enough work to say its better or worse than the daily or other timeframes (eg. H4, H6 H8).

One possible advantage of the H12 vs Daily I guess is probably that more traders focus and trade the daily than the H12, so some H12 trades/levels would not be as crowded.

Most of my trades and most of the return occurs on the overnight bar, not the day bar (the average range for the overnight bar is typically about 5-10% larger than the day bar reflecting the level of activity between the Asian and Euro/US sessions).

Also for me with the style of price action trading I am following, most of the setups I use I have found have their optimal duration at 2-3 bars (on average over the long term), so there is a big difference in trade time in market between H12 and daily from 24-36 hours for H12 to 2-3 days for the daily - why risk money in the market for twice as long if not necessary - I have done enough work to believe that if I traded the same model on the Daily instead of the H12 then it would essentially take twice as long to generate the same return (again, using my style of price action trading).
