Quote from ProfLogic:
I understand what you are saying but try solving any problem using 99% of the necessary information and let me know how that works out for you.
If the overnight data of the chart you are watching makes a new high, a new low or any critical oscillation, by omitting it you are artificially skewing your information set to totally work again your decision making process.
What you are doing is not done or even considered in any problem solving situation so why do traders think it is acceptable to apply this practice to technical analysis?
