AN EXPERT ADVISOR BASED OF MY INDICATOR BY USING GRID STRATEGY

I have my own custom indicator...which provides buying and selling signals....I want to build the EA in such a way that any indicator I can attach to it....any first initial BUY OR SELL trade will be based on the signal given by the indicator. .. if the trade goes to the opposite direction then its grid orders should arrive at the distance determined as per the grid strategy... and an average target point of all grid orders should be set as many grid orders arrive...

IF EA TAKES FIRST INDICATOR SIGNAL  BUY TRADE...NO INDICATOR SIGNAL BASE BUY TRADE SHOULD NOT BE TAKEN UNTIL FIRST BUY TRADE EXITS.. IF THE INDICATOR SIGNALS gives SELL TRADE WHILE THE FIRST BUY TRADE IS ON AND HIS GRID ORDERS ARE OPEN  that sell trade should be taken by EA...and if that sell trade goes in opposite direction then grid orders should come as per the determined distance...

Note:- Grid orders should be placed on the basis of determined distance only...indicator signals should not have any effect on it.

inputs, specification, calculations, drawing etc... required for making EA will be provided...

I need a developer who understands trading and knows grid setting...and can do justice to this simple strategy..
