Was going thru some charts and came up with this masterpiece and the way the ribbon system might have been of immense help
This is a chart of 20700 PE of this thursday (the last expiry) The signal to go long came at 2:35 at Rs.9 with a sl of just under 6.25 by the ribbon system. You may call it hindsight but just observe the bottom OBV pane and you would see that the 60period OBV ribbon had turned blue at around 12 (that is the time when the fall started in BN) the point i am trying to make is that on expiry day if an option has to become worthless then a lot of selling/ unwinding in that option takes place because to the market makers it is a free trade (they would be willing to pick up those 8-10 rupees also from gullible small traders) That unwinding would have resulted in the higher period (60 period) OBV ribbon to turn red if the selling of this option had taken place. In fact it was telling us the opposite. It was being bought by the market makers. It went on to make a high of close to Rs.100 in less than an hour of trade before expiring at Rs.80. A true intraday multi-bagger. Zero to Hero. All the parameters for taking this trade were being met. We had made a higher low in the red ribbon period in the last red period from the one before that. So it was not meant to be a mere punt but a rule based entry.
