I want to draw many horizontal lines across the chart and use them as some kind of grid. I want to have a certain distance between any two of them. That "gap size" has been determined by eye. I look at it and decide whether it's good or not. My first

I am toying with some ideas for a future indicator and I am stumped at this problem: The indicator draws some lines across the screen as soon as it is loaded, as expected. Then I save the chart as a template. Then I load the template in another chart

A negative MA shift value works fine in charts, but returns 0 in MQL4 code. Why is that? Please don't tell me that "we can't look into the future." That is not the point. The point is a that negative MA shift value plots a certain position in the

Suppose I run my EA in the 15M or 1H time frame, and the EA makes decisions also based on higher time frames such as 4H and 1D. Does Strategy Tester "see" the other time frames? I am inclined to believe yes, searching on google suggests that, but I'm

I decided to use the email notification feature for the first time. I opened the Options in MT4 and configured my email address, SMTP etc. Then I pressed the Test button. MT4 said: Message was successfully queued! Look at journal for more information

All my Market indicators are disabled. All of them (7). None is paid for, they're all free. MT4 required a login, I did it. So I found one of the indicators in the Market tab and there is only the "Open" button. When I click it, the indicator is

Every timeframe has a large "unit" period whose end/beginning is marked by a dotted line on specific milestones: - from M1 to H4 it's on every 0h00; - on D1 it's on the end/beginning of every month; - for W1 and MN, it's on the end/beginning of every

My code: #include <stdlib.mqh> (...) Print ( "Last error on " + _Symbol + ": " + IntegerToString ( GetLastError ()) + ": " + ErrorDescription( GetLastError ())); The log panel prints: Last error on EURAUD: 4108: no error I check up on the error

Suppose an old bar, say index 15 is bullish. The timeframe is 1H. I want to probe for the state (bullish/bearish) and possibly other data (iopen, iclose , EMAs etc.) on each 15M bar that existed inside that one bar when it happened. How can I achieve

I have an EA running on more than a dozen pairs. Every time I edit the code, I have to manually switch to each chart and manually reload the EA because the new code won't go into effect automatically. A real pain. That also applies to templates. Even

I would like to have something like this in the screenshot. It's obviously a mock-up I made in an image editor. I don't need candles. Just the moving averages would be fine. The code repository is so large no one can possibly ever see everything in

My code is supposed to display a clock on the chart. In this case, I am displaying seconds only. The problem is that I set the loop to run every 40 milliseconds with EventSetMillisecondTimer(40). Considering that 40 milliseconds happens 25 times at

Can I have/make a custom indicator in a separate window that displays text only? I've read the manual and seen many examples of indicators, and it seems there is no such option. Is that correct? TIA

I have an EA that runs almost everything onTick() and a script that creates a plain text file. A keyboard shortcut launches the script and the EA's onTick routine detects the presence of the file. That is how I tell my EA to execute certain tasks

I want to look at a chart at a given timeframe. Say, H1. And I want to have a Stochastic indicator beneath it, in its own window. It comes bundled with MT4 so I just have to drag and drop it. Now, I also want to have another Stochastic indicator in

At the top of this page, there is a figure showing prices above and below each bar: https://docs.mql4.com/constants/objectconstants/enum_object/obj_text I am a newbie at MQL4 and reading that code is still hard for me. It seems that you can't anchor

I want to copy an EA, change it and make another fairly similar EA. The EA uses an .mqh include. I open the include in Meta Editor. I press F7 (compile). No errors. I drag and copy it with another name. I open it in Meta Editor. I make NO CHANGES to

I have a few functions inside void OnTick()  {} that run on every tick and draw/update data on the chart. All of them work except this one: void drawVLine()  {    string name = "VLine" ;    if ( ObjectFind (name) !=

I am a neophyte in MQL programming and have been trying to develop my own EA. It has a pretty good performance on Strategy Tester , but loses money when it goes live. This week was the ultimate test. I left it running for the whole week in a demo

I made a very rough indicator with ObjectCreate/OBJ_TEXT that floats next to the current bar and I have these problems with it: - How do I position it? It is not just too close to the bar, it actually writes text over the bar and looks bad. I "fixed"
