A Simple Back-testing Problem
| int OrderSend( | string symbol, int cmd, double volume, double price, int slippage, double stoploss, double takeprofit, string comment=NULL, int magic=0, datetime expiration=0, color arrow_color=CLR_NONE) |
Your lot size -- the volume parameter -- is being rejected.
MarketInfo(Symbol(), MODE_MINLOT) -- smallest size for a trade
MarketInfo(Symbol(), MODE_MAXLOT) -- largest size for a trade
MarketInfo(Symbol(), MODE_LOTSTEP) -- increments of lot size
Many Thanks. Apparently, a mini-lot is now considered 1 rather than 0.1, despite a variable "Lots" being considered a double. Thanks again.
MarketInfo(Symbol(), MODE_LOTSIZE) gives a clue to that.

Hi all,
I'm relatively new to this user interface, and I'm having a problem not described in the help section. Whenever I attempt to back-test one of the given EAs, I always end up with these two error message in the Journal: "OrderSend error 131" as well as "Error opening BUY order : 131". I'm using a demo account.
