Custom indicator made into an Expert Advisor for Metatrader 4

Hello, I need an Expert Advisor (for metatrader 4) that follows the signals from my custom indicator This indicator was made by a russian guy. I now use it manualy but would like to automate it! The indicator gives a buy and a sell signal! the EA has to open a buy order on the buy signal and has to close the order when the sell signal comes, Then it has to place a sell order and closes that on the buy signal and so on.. Trade up and down!!! And has a stoploss in dollars and takeprofit in dollars ! Further info will be given on reply. Best regards, S d B
