There are many extra possibilities that could have been used in the poll such as - M2, M3, M4, M6, M10, M12, M20, H2, H3, H6, H8, H12, 10 tick, 20 tick etc.
I just decided to go with the MT4 timeframes in the poll (leaving off weekly & monthly, as i guessed most people use lower TF's to these).
People might then select them all. To avoid this you could have say - 2 choices max. But then - you could ask - well of those 2, which do you like best?
So maybe, if 1 isn't enough, "other" and stating the time-frame in the thread might be the best option.
The poll & the following discussion should kind of be of equal value anyway.
The only problem is if for some reason, certain people would prefer to keep their preferred timeframe a secret, though i don't see why they would.
I base most of my decisions off the daily chart, however I always look at the 4 hr and 10 min charts to see if I can time my entry better. The same with exits. The decision comes from looking at the 1 day/4 hour charts but I'll look at the 10 min chart and if the short term price movement is favourable I'll hold onto the trade for a little longer.
