I TRIED TO LOOK AT ALL INDICATORS TO SHOW SOME SORT OF A WEAKNESS IN BANK NIFTY FUTURE. FINALLY I USED THE WILLIAM % @ OVERBOUGHT/OVERSOLD CONDITIONS. ON AN HOURLY BASIS, PRICE HAS CLOSED BELOW 5 EMA .... AND THE WILLIAM% INDICATOR HAS TURNED DOWN.... IT IS - 17.77.... AND A DROP BELOW -20 IS THE 1ST SIGN OF WEAKNESS..... AND A DROP BELOW -50 WOULD MEAN THAT THE INDICE WOULD GO ALL THE WAY DOWN TO OVERSOLD LEVELS..... HERE IS JUST AN IDEA/ METHOD TO TRY AND SEE THE VARIOUS POSSIBILITIES
