EA based on currency pairs comparison model

I want an EA which will compare the Currency pairs and then execute the order accordingly.

I want the EA to compare the cross pairs and change in percentage from open of the candle to currency price in candle and then open the order according to the condition

conditions 

-If the pair selected is EURUSD then the EA should compare with EURJPY and USDJPY changes of % and if we found EUR is stronger compared to USD the it should open EURUSD BUY ORDER

-The Change of percentage is calculated as the Open price and current price at time of opening order

-Give EA option for order open at a particular time and the time of order opening is set by user and EA will check the satisfaction condition and open order at that given input time.

-If the change in % of EURJPY is in -0.1% and USDJPY is +0.1% then it implies that EUR is weaker and USD is stronger then EURUSD sell order should open.

-Give and option of putting a median % for order to open lets say 0.05 is median

-If the % changes of the pairs is +0.04% or -0.04% then there will be no order placed as the % median is minimum of 0.05.

-If the % changes of the pairs is +0.06% or -0.06% then order can be placed with the condition satisfactory as values are above 0.05

-Give the EA for entering currency pairs input as we can give input of EURJPY USDJPY FOR EURUSD similarly FOR GBPUSD GBPJPY USD JPY

FOR EURGBP EURUSD GBPUSD.
