Does anyone know of a free EA that can do the following:  1) Let you set a pending order with initial entry, TP1 and SL 2) lets you input TP1, TP2, TP3, TP4,....,TPn (each one definable by user, per trade).  For example: TP1 = 20 pips TP2 = 40 pip TP 3 = 100 pips TP 4 = 150 pips  in one instance....
Hi all, instead of the default - Pass, Profit, Total Trades, Profit Factor, Expected Profit, Drawdown, How can I obtain Profit Trades (%) in the Optimization Results? Or can I derive the profit trades from these parameters? Thanks.
Yo, juste a simple question, how to know the opening date of a selected order ? I mean I got 5 orders open and still not clotured, and I want to know the date when my EA opened a selected order... Thanks in advance
Уважаемые разработчики. Просьба прокомментировать ответ брокера : Цитата : "Отвечаю на Ваш вопрос по поводу отсутствия минутных котировок за 2-3 года. Разработчик программного обеспечения MT4 установил ограничение на количество отображаемых тиков на графике и то что мы выводим на график, это тот...
Why I've differents results in 3 PC with same parameters in entry, same dates range and same broker ?  I've the follow results.  - Backtest in First:   - 2nd Backtest: - 3rd Backtest   
I thought this might be helpful. I found the original somewhere on the net and expanded on it. It should be noted that many of these commands should not be used because the MQL4 language provides better, cleaner, alternatives. Occasionally though, you find you need to accomplish a particular task...
I have installed MT4 manager to a Windows 8 based laptop. It has an error of public key not found but i already put the appropriate registration entry on the manager. Does it means that the MT4 Manager is not applicable with windows 8? Thanks

Hello all,  I am trying to write a very short indicator that I can run in back test that will show me how deep a draw down goes during a set of tests. I am looking at Martingales type of trading systems in some EA's. If the draw downs are not too deep they will close out as profitable in the MQL4...
you know how on the charts, you can apply one indicator onto another by clicking, "apply to first indicator's data?" how can you do the same for programming in mql4? For example, I want to create a strategy that involves bollinger bands on RSI values. 
H1 EURUSD FROM 2001 with 2% risk per trade. I am looking at the areas that need improving. Test has been confirmed with a tick test (EA uses open prices).
Hi there! I'm new to the community and to the idea of algo trading, and I'm in need of help with coding my very first EA! What I did is that I downloaded EA from this link: https://book.mql4.com/samples/expert and tried to modify 'Trading criteria' in order to meet my expectations. Of course my...
Some of the EAs I have a lot if inputs. Example 20 symbols, 10 ten frames and 32 patterns. The configuration with in Metatrader is a not pretty. So I had a QT app built currently it is a EXE app( later in the summer I will tackle it for a real time interface. Right now it reads and writes data to a...
The biggest (greatest) ticket number always corresponds to the last (the newest) order of the account. Is it true ?  Ticket(order A) > ticket(order B) ---> Order A was opened after the order B was. Is it true ? 
It is inconvenient not able to modify the order magic number. The order comment, too. 
What folder which MQL4 keep history data ? Thank you
Hi, When testing EA's, are you more concerned about the max or relative drawdown, perhaps both? I think max drawdown is more important as this determines the drop from the "balance" whereas relative determines the drop from the "equity". This way I know what I could expect from the worst possible...

Hello all, On currency tickers (e.g EURUSD)  I get the chart and the H1 or H4 data is bar aligned on the hour so I get bars that are timestamped as 15:00, 16:00 or whatever. The problem is that for some tickers (#AA and #C) I get the H1 and H4 data bar aligned on the half hour, so the bars are...
As humans, we can readily tell when we have live data feed and when we don't.  But just try to write a code for insertion into a custom indicator that can tell, during times when there is no live feed (weekends, holidays, etc.) that there is no live data feed!   I don't think it can be done, but if...

Hi guys,       I am looking for two answers here. First to partially close an open order automatically on a specified profit target. I know that i can do that manually at market value by right clicking on the 'order', going to 'close order' and change the 'volume' as desired and close the partial...
This was an indicator that I am trying to make into an EA.  I am trying to do one thing at a time.  I am just working the buy side.  Pls notice that strategy tester placed a buy order about 16 pips above the high of the bar.  Why? I am using Ask in the OrderSend function.    Journal 2013.04.12 23:09...

Hello all,  I was trying to make a scalping EA, but I can't figure this thing out: It immediately closes all it's positions. Been looking over it for hours now, hope one of you can see it. I guess it has to do with the TP/SL. The reason I don't use the OrderSend function for that, is because my...
Hi there,  I was wondering the if the community could help me out in respect to defining what 'current chart' means in https://docs.mql4.com/series/iBars.  We have the following in our code: int bar = iBars(symbol, PERIOD_M5);   What we don't understand:  When we loop over the symbol set, we get a...
