By the time we realise what kind of trading day it is, - its almost over. So I personally believe, we should stick to the trading system which has been tested, tried and proven by our own selves.
As day trader - this skill is must . Range bound = av .8 ATR , after crossing 1 ATR ,i defined up or Dn, - at start , nobody knows , but soon with Order flow ,Early reversal sign,Holding of Imp pivot - we can guess (proactively) the DAY,- quick swing up/dn = volatility
Normally within 15min u must be able to define it ,next is REFINING. When it starts to move up - i dont know how far it shall move, but very easily OR with strong thrust if its moving then i know -HOLDING winner now gives more money.
Pl understand ,we may start with a bias, in that our psychology must be able to change it ,as per terms of market. On the contrary if we have NO BIAS , individual day is different (new opportunity , flexible to follow price action )- then easily we learn to bet RIGHT side with higher ODD. Now some FIB trader use a bias on particular RETRACEMENT VALUE- some uses particular SUPPORT pt, some use AFTER GAP FILL directional bias , many uses X-over bias , some trader uses stockastic reversal - but U MUST NOT BE BLOCKED ,GET OUT EARLY IF PROVEN WRONG BY PRICE, but hold more time when u gripped it right.
dilemma is traders worst enemy - in Efficient Market learn to act quickly
