Write Trading System in Multicharts

Looking for someone to write a system that can trade multiple pairs. (Written in C# and Easy/Power Language) Strategy is very basic. Read Parameters from Excel File Take the ratio of prices (RATIO) of A & B Futures and calculate a moving average of that ratio (MARATIO) with params (from ExcelFile). Calculate a spread [(RATIO - MARATIO) / MARATIO] Calculate a Threshold based on SD of spread over a time period (from params) If within Trading Times (set from Param file) If Price > Threshold Sell A at limit price Once filled Buy B at Market else Price < Threshold Buy A at limit price Once filled Sell B at Market end end Once spread reverts back to % of SD (taken from params) Reverse trade and flatten Execution is important - should be able to passively get filled on one side Also, should be able to throttle size shown based on instrument characteristics (param file) Need a front end with buttons able to control each strategy Save (Save state posns / avg prices) to SpreadSheet Pause (Pause trading) Flatten (flatten positions) Exit (close tidily and exit Strategy)
