And I would only add that your instruction is supported by my method. Personally, I investigate the unique characteristics of a specific instrument/symbol in a chosen market and then go about building an EA for it. If one believes in this method, one must know the specific instrument/symbol for which the EA was designed and preset. I would avoid any EA advertised as or implied to be "universal." Even where one has the designated symbol and settings, one must do his/her own backtest(s) due to differing broker-dealers, data feeds, trading machines, connection latencies, spreads, commissions, etc.
