Buy/Sell Script for 15 mins Candle

Can I request someone to write a script for 15 mins candle for MCX Silver at 2:00 to 2:15 pm, or any 15 mins candle. I want to place a buy order if that candle reaches a certain level I want to place buy order @ -200 points and @ +200 points for sell order of that specific candle. Any help would be deeply appreciated. Thanks ~Haneef
