Need a programmer for very simple HEDGING BOT for a good money

Hello I am a forex and comodities trader. I just need a very simple algorithm or a bot. I want a bot which should activate a buy/sell trade after the market crosses a price which I have indicated.In other words I need a hedging bot which will hedge same number of lots if the trade goes against me automatically. Since markets are volatile, so if market comes back in my favour, the hedging should automatically be closed also.  For example, I have bought 2 lots of gold at 1600 and the market comes down to 1598, the hedging should be activated when the price goes opposite to 1600 towards 1598. And if price rebounds back towards 1600 and crosses 1600, the hedging should be automatically deactivated. This should happen every time the price crosses below 1600.
