Require EA to make trades following a specific indicator

Hi

i am looking to have an EA script written to specifically open/close orders following the superttrend indicator.

1. Expert advisor based on supertrend indicator

2. This Expert advisor should take input for initiating a long or short position fron supertrend indicator

3. Should open the order, close the order, put up a stop loss, trailing stop loss and exit the position and automatically initiate another position, should give audio alarm

best
