The formulae in experts, explorations and system tester for the above plug-in are password protected. The manual implies that the system is designed for open next bar entry but it is not clear how one should handle the system tester. All orders are market orders (consistent with entry at open) but I am not sure about the use of entry exit prices in "System Testing Options" - "Trade Execution" - "Trade Price". For a correct entry/exit on next bar, "realistic market prices" should be unchecked and all prices should read "open" and "Delay order opening" should be zero. The latter works if and only if entry conditions/setup are written with a bar delay. Now there is no assurance that this was done in ETS and no way of verifying owing to the password protected formulae. Obviously, this makes a big difference in results because applying open prices to a signal without setup tends to improve results relative to close entry/exit. Has anybody any comments on the above issue. Thanks. Maurizio
