My ea editing

hey, i have a existing robot which trades following an indicator so if the indicator take out a buy signal the ea will buy vice versa ,now i want to remove the current indicator and put a new one which i will provide 

i want the settings to be the same, the indicator will take out a signal with a entry point stoploss and take profit

the indicator has 3 colors 

Yellow -entry point

    Red -stoploss 

 Green -take profit

i want the ea to buy or sell on the entry point which will depend on the indicator signal and if its a buy the ea should place a buy on the entry point and if the candle moves above the entry point the ea should move the stoploss to the entry point and if the candle reverse back to the new stoploss  "which is the entry point" the ea should exit the trade, when the candle goes back up the entry point which was first  initiated by the indicator and same principles applies of the stoploss vice versa with a sell signal.
