Nifty opened near PDH.BOF of PDH/BRN gave a short signal. Hesitated to short below the pin bar. IR formed. Shorted on break of PDC. Thought it will move through the fluid. But RN of NS gave support. Covered shorts above the pin bar high. Attempted two BOF trades at range high and range low of 10 point range expecting the break of other extreme. Both trades scratched. Missed the last fall.
