Hello - I have written an indicator that uses the OnChartEvent event that draws lines onto the chart. When this indicator is loaded by an EA using IndicatorCreate, drawing the indicator on the chart is not required. Although not drawn on the chart

Hi If an indicator uses multiple classes and functions, as one might have if writing a non-simplistic indicator, then the lack of support for array pointers makes it necessary to pass references to data arrays from class to class and function to

Hi I have an indicator that processes a lot of data. It published successfully around a year to 18 months ago. Now I get Tester Takes Too Long during publish validation. The code is already highly optimised. Is there anything I can do to get it

Hi In an indicator's OnInit() how can I detect if the indicator has been loaded as a result of IndicatorCreate()? Rob

Hi It appears that a program's OnInit() and OnDeinit() do not get called if there is an indicator handle opened with ChartIndicatorGet() and not yet released with IndicatorRelease(). My indicators and EAs need to retrieve indicators' buffer data

I'm writing an EA that I plan to publish. This EA includes my own versions with modifications of some indicators in the Indicators\Examples folder, including three that are not in this folder - SuperTrend, TSI and Keltner Channels. All the code is my

How do I stop the main chart from receiving events when a dialog window is open? When a user click/drags over the dialog window, as they would to interact with controls on the panel the event gets passed to the chart behind. Obviously this is

Hello I would like to have a group of controls on a CAppDialog that I can make visible/invisible and replace with another group of controls on the same CAppDialog. So, the main AppDialog would have a group of buttons below the caption that control

How do I retrieve the index of the currently selected list element? Thank you

Hi I have written a .dll library for my EA, using Visual Studio 2019 that has a dependency on another dll,  System.Text.Json.dll. Where should I place this dependency dll? I have tried copying it to MT5\Libraries, but get a File Not Found

Hello Why does CopyTicks return ticks that are older than the [in] date parameter? From the documentation: [in]   The date from which you want to request ticks. In milliseconds since 1970.01.01. If   from =0, the last   count  

Hello I have an indicator that draws several rectangle objects across the chart as part of support/resistance lines. These objects are drawn in the OnChartEvent when id = CHARTEVENT_CHART_CHANGE. The indicator has been recompiled for the latest

I have a chart sub window that draws a curve using the CurveAdd function of the CGraphic class in the Graphics Library. I would like to add some text to this curve, such as a label in the top left of the window. I have tried using AddLabelObject but

I believe this to be a bug in Include\Indicators\Series.mqh method CheckLoadHistory currently: if ( MQL5InfoInteger ( MQL5_PROGRAM_TYPE )== PROGRAM_INDICATOR && Period ()==m_period && Symbol ()==m_symbol)

I have an indicator that uses iCustom and CopyBuffer to load the data from another indicator (same symbol, different timeframe). CopyBuffer will usually return -1 on the first call of OnCalculate(), meaning data is not yet available. This is not

I have discovered a bug in one of the Standard Libraries: \Include\Indicators\Series.mqh in function CheckLoadHistory. How do I contact Service Desk? There is no link for Service Desk on my profile menu as some pages indicate. Other pages tell me to

Hi, I'm a veteran programmer but relative newbie to MQL5. I have written my indicators and now need some documentation, help, guidance etc on writing an EA for strategy testing and automated trading. Please can someone provide some links for articles

For example, the following code works as expected. The first plot, with plot index 0 uses data from buffer 0 and the second plot with index 1 uses data from buffer 1. Does this mean that the plot is associated with it's buffer by it's index number

I have an indicator that creates several chart objects as part of the indicator, OBJ_TREND, OBJ_HLINE, etc. I then create a template of a chart using this indicator. I then open a new chart on the same or different timeframe and load this template
