Need closing script..

Need closing script to execute stop loss of manually opened trades.

Once the trade is opened i would like the script to automatically attach to open buy trades and execute stop loss orders if/when

any following candle closes below the low of the opening candle.

And vice verse for short trades. To execute stop loss if any following candle closes above high of opening candle. 

Greatly appriciate the help.

Thanks.  mike.
