TradStation versus MetaStock functions

[Randall_Gary@xxxxxxxx]

     I'm converting some TradeStation code to MetaStock.  In comparing 
     results I've found that some functions don't return the same results.
     
     For instance, MetaStock's ATR(45) function seems to return the 
     correctly smoothed results according to Wilder's book, but 
     TradeStation's AveTrueRange(45) doesn't.  It actually returns the 
     simple moving average of TrueRange, the MetaStock equivalent of 
     mov(ATR(1),45,S).
     
     The TradeStation ADX(14) doesn't compare well at all to MetaStock's 
     version.  While MetaStock returns rounded integer values as Wilder 
     said, TradeStation returns fractional values which can't round to the 
     MetaStock values.
     
     Does anyone know how to simulate TradeStation's ADX results in 
     MetaStock?  I need to duplicate TradeStation's results in order to 
     achieve the same results as the TradeStation system.
