Hello Is it possible to have the very useful Polyline code in a separate, self-contained library file? Because I've had issues getting the code to compile, it seems integrated into the trading functions of WHRea.mq4 but I just want to display the

Hi I tried to access forum/mql4.com just now, all I got instead of the website was a goobledygook string "Служба недоступна." Has the site been hacked or something, or is it my laptop? Thanks

I've noticed around in the forum various references to Polyline, by WHRoeder. As I understand it, it allows an EA to draw lines on a chart the way an indicator would. https://www.mql5.com/en/forum/130907 Is this correct? Is it usuable within Strategy

Hello What is the difference between these two functions , because in the documentation the descriptions are very similar? Thanks in advance

Is it possible to write a successful EA? What does the code of such an EA look like? Are there common design patterns / sections / tools that successful EA's share? Do they all use the 'standard' indicators that come with MT4, or custom/proprietary

I'm trying to debug a dll through VS. When I set the exe to metatrader's terminal.exe, it tells me "A debugger has been found running in your system....". When I try to attach to an already running instance of the terminal, it crashes. A google

I think I am overlooking something patently obvious here     myVal = GlobalVariableGet ( Symbol ()+ "_ADR_R5" );      double ratio;     ratio = myVal/totalR;

Hello! Where is the bug database for Metatrader Terminal, ie, when a user finds a genuine bug (and several other users confirm same problem), and logs the bug? How do I check which release version a particular bug has been fixed in? Thank you! P.S. -

Subject says it all: Dukascopy vs. Alpari? And does it make a difference

Hello I feel sure that there is an answer in a post somewhere to my problem - but I cannot find it despite a search. Basically a custom indicator displays different values for one of the indicator lines (thick line, purple/Plum) when dropped onto

Hello To the coders: Is there anything I particularly need to watch out for in creating an OrderSend for a live account? I've attached a piece of code that seems to work fine - in StrategyTester, probably even in Demo. I just want to make sure bases

Hello! I've looked in the forum but cannot find anything. Before I go and code it myself, I thought I would ask - is there an equidistant channel indicator? Something I can access from within an EA? Thanks very much

I've noticed that the indicator signals given in forward-testing in realtime are more frequent, and do not match up to the signals if the indicator is run over the same data historically (hope you understand what I mean). When an indicator is first

Just found a reference to this in MQL doc: "Global variables are available within four weeks since their last call from experts or manual modifying." I take this to mean that, if you create a global variable, whether in code from an EA, or

Hello I have an EA that performs well in backtest and I am trying to take it to the next level - performing on a demo account . But I am lost as to what is good practice to make it reliable, robust to recover from MT4 crash. E.g. - error handling

Hello I am trying to understand why/how an indicator (DT-ZigZag-Lauer) returns different results from an EA than when it is attached to a chart. I have checked and re-checked the code (see attachment). If anyone can help, of has an explanation, I

Hello Sorry if this is a stupid question. I want to use BB in an EA I'm writing. However... why do the figures from the iBands function not agree with what I see on the chart with the BB indicator? All the iputs are the same, the date is the same

Hello I have been getting strange behaviour from the MT4 Strategy Tester . I started testing an EA with 1 years of historical data at a time. 2001-2002: fine, 2002-2003: fine, 2003-2004: fine, 2004-2005:fine, 2005-2006: fine, 2006-2007:fine. Then I
