itc has formed beautiful rally base drop pattern on daily time frame. big hni, banks, mutual funds have initiated selling at the supply zone marked in red. the sell orders placed are not completely sold .so, this leaves some sell orders pending.. what we try to do is when the price comes back to the supply zone marked, pending sell orders of big institutyions get triggered.. we have also placed sell orders.. poor retails traders with greed buy the shares at supply zone, we wwill join hands with big institutioins to initiate strong selling again.. this is the mechanism of this type of rule based demand supply trading
