Indicator Help to draw arrow after x pip move

Hi All,

Need some help with my indicator. Please find the code below.
It's is supposed to draw arrows in regions where price moved more that "X" number of pips within the last 20 bars hence:

Open[i] > (Open[i+20] + PriceMove * Point) )

It draws arrow fine on the chart where i want them, but for some reason, does not update live. If have to restart the indicator and the arrows appear after that only. Please advise where there error in the code is if you can.

Rgrds and thanks in advance,

change :

to
