Normally it drops from the beginning of the market..
Drops and settles for the lowest price for that day..Blinks (Dropping) two or three times from the lowest price. This is the best price to collect GRAN. Then at around 11 O'clock it starting to run (Move) fast. Buyers have to be careful at this time.Don't sell them for 1 or 2 rupees.Hold it after 1.30pm and look at the movements. After 1.30pm decision is on your hand. "Hold or Sell"..
Better if you can hold for the next day's run..
