It uses the reverse market position option, but fails when forward testing on a real mql4 error account: 2015.02.16 17:59:59.599 Strategy 9.7 EURUSD,H1: 2015.02.16 20:00:09 Error opening order: 129 : invalid price 2015.02.16 17:59:59.599 Strategy 9.7 EURUSD,H1: 2015.02.16 20:00:09 Opening order, direction: 0, price: 1.13572, Ask: 1.13572, Bid: 1.13548 2015.02.16 17:59:55.489 Strategy 9.7 EURUSD,H1: 2015.02.16 20:00:05 Error opening order: 129 : invalid price 2015.02.16 17:59:55.489 Strategy 9.7 EURUSD,H1: 2015.02.16 20:00:05 Opening order, direction: 0, price: 1.13572, Ask: 1.13572, Bid: 1.13548 2015.02.16 17:59:52.067 Strategy 9.7 EURUSD,H1: 2015.02.16 mql4 error code 20:00:01 Error opening order: 129 : invalid price 2015.02.16 17:59:52.067 Strategy 9.7 EURUSD,H1: 2015.02.16 20:00:01 Opening order, direction: 0, price: 1.13572, Ask: 1.13572, Bid: 1.13548 2015.02.16 17:59:52.052 Strategy 9.7 EURUSD,H1: close #164716296 sell 0.10 EURUSD at 1.14383 at price 1.13572 Any idea why the EA does not appear to be able to open the opposite trade direction after closing a trade? Thanks, Mike Back to top Report #2 mikeyc mikeyc Advanced Member Customers 822 posts Posted 16 February 2015 - 08:04 PM Mark, Looking at the trading logic in the generated EA, it looks to me like it retries regardless of the cause of the error, and in the case of error 129 it should refresh the bid/ask as the price has moved beyond the slippage. See http://forum.mql4.com/61528 For my own EA's I use a library called OrderReliable to handle the tricky error handling required. https://github.com/k..._2011.01.07.mqh Maybe include this in the next version of the SQ template for MQ4? Regards, Mike Back to top Report #3 Mark Fric Mark Fric Administrator Administrators 2,896 posts Posted 17 February 2015 - 06:55 PM thanks for letting me know about this error and library, I'll look at it.

Closing and Deleting Orders Modification of Orders Use the opportunities of MQL5 in MetaTrader 5 Want to study new MQL5? Read MQL5 Reference Download MetaTrader 4 Client Terminal Opening and Placing Orders Trade requests for opening and placing pending orders are formed using the function OrderSend(). Function OrderSend() 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) (please note that here and below, we refer to function header, not to an example of how to use function call in a program). Let's consider in more details what this function consists of. OrderSend is the function name. The function returns the ticket number ('ticket' is the unique number of an order) that is assigned to the order by the trade server, or -1, if the trade request has been rejected by either the server or the client terminal. In order to get information about the reasons for rejection of the trade request, you should use the function GetLastError() (below we will consider some of the most common errors). symbol is the name of the traded security. Each symbol corresponds with the value of a string variable. For example, for the currency pair of Euro/US dollar, this value is "EURUSD". If the order is being opened for a foregone symbol, then this parameter can be specified explicitly: "EURUSD", "EURGBP", etc. However, if you are going to use the Expert Advisor in the window of any other symbol, you can use the standard function Symbol(). This function returns a string value that corresponds with the name of the symbol, in the window of which the EA or script is being executed. cmd is the type of operation. The type of operation can be specified as a predefined constant or its value, and according to the type of the trade. volume is the amount of lots. For market orders, you must always check the account for the sufficiency. For pending orders, the amount of lots is not limited. price is the open price. It is specified according to the requirements and limitations accepted for making trades (see Order Characteristics and Rules for Making Trades). If the price requested for opening of market orders has not been found in the price thread or if it has considerably outdated, the trade
