I find if the day range is greater than specific value then it is much easier to catch trend in day trading I creat an indicator to measure it dayrange/ATR of a specific time frame the greater the indicator , the easier to catch the trend in day trading
you fancy yourself a smart bloke eh well guess what, been there, done that, long ago, and moved to better ways
The problem is that you don't know how much will be today range until tomorrow (or until the close). Speaking of ranges, short range days or Candlestick stars, often signal a pivot point (at least short term).
