can anybody help to modify this pivot formula

#1
hi guys i have found this pivot afl here at the site.......i m sure many of u have seen it....there 2problem with this afl ==

1) the arrows get vanished in case of wrong trades....arrows shuld remain so that we can see wrong trades also nd test it...

2)the arrows of buy-sell comes aftr 1 day delay

can anybody rectify/edit this formula so that these problm gets solved =

amit,

pivot is a pivot. during the course of a candle forming, depending of LTP, the body of the candle will change thus giving u the ohlc. no one can predict a pivot until clear trend emerges. that is why the arrow appears and disappears during and most of the times after many candles have already formed.
end of day everything will look spic and span, make u wonder oh.. i short here... i buy here... look at the profit...intraTrading is not so easy and needs human intervention... important to indentify pivot behaviour by watching... who can say when candle is forming ...where its going to go...

yes vinod ji...u right we need human intervention nd air i m willing to learn .....sir plz can u share any of ur good strategy which i can learn nd use....i m willing to learn nd become self dependent rather than depending on others for tipsss
