hi talisman.
that is RSI indicating a sell. when even RSI falls from overbought zone, RSI gives a sell( red) signal. like wise iwhen RSI rises from oversold zone, it gives a buy(green) signal.
for further details you can refer to

BTW, if you want to buy it now, wait for a 5&6 crossover or Bullish piercing of the Bands.
Also, keep in mind the suggestion of bunny, that there is no professional interest in the share.
cheers.
