been trading the ES for the last two years so i have a question for stock traders. Back in 2000, daytrading a position for 10-30 minutes could be done with positions not exceeding 1 % of the stocks daily volume. ( i.e.- if daily volume was 500,000 you could take a position up to 5000 shares). NOW WE ARE IN 2002 . so with the changes of all types in the last two years what are the current trade size parameters that can be used daytrading.( want to be flat by 12 noon). thanks
