mmhh an interesting question . time frames are not easy. there are many approaches however from how ive been taught and actually trading it, there are several good time frames.
the key to the time frames is the system , stratedy your using. i dont trade ticks , generally i will trade in minutes time frames and gnerally sue multiple time frames to fully gear my positions short term.
so mu suggestion is work out some basics,
1 can you simualate your strategy
2. can you test it ? and there fore can you test in different time frames
3. you must work out your risk to positions and useof stops involved vs. your allocation.
4 once you have this , you can find time frames which work well, above all you MUST know what your daily and weekly trend / direction is !! coz if you are short term and you are trading against the daily trend YOU WILL LOOSE YOUR MONEY ....
im not giving you my time frames , traders dont give out tiimefrmaes that work : ) what i can say is shorter time frames are generally above 4 mins per bar in the dax / stoxx
good luck
