Forex Trading - Meta Trader 4 - Indicator Coding

Hi Everyone: I have this indicator that I use to trade Forex. It will alert me when to buy and when to sell but I want to be able to make it that it buys and sells without having me placing the order (Autopilot). And I should be able to change the setting for followings, so they need to be added: Size of the trade Stop loss based on the numbers of pipes Take profit based on the numbers of pipes And I will be trading EUR/USD if it makes a difference for coding. Good Luck,
