Quote from BSAM:
Why not use the time frame which gives you the most consistent positive results?
Why not drop "indicators" and learn to read price action/volume?
There are 2 steps...
1) Do what BSAM says and you'll have a solid core that you can build on if you want to try indicators later.
2) Once you have developed a trading style on price and volume, then do what James Pond says.
The 1st step is hard and the 2nd harder as you will see reading posts on ET.
