Hi,   I am a fairly experienced coder and I have sort of gotten stuck on this one.  I have a lot of text to put on a chart and I am using multiple labels. My client has asked for it to be translated into Chinese at some point. The client will be paying for a professional translation but he wants me...
Hi. I have 2 EAs running on  a Demo account and the same 2 EAs on a Live account. There is more money in the Demo than in the Live account. The EAs in each account have the same input parameters. At this very moment the Demo has 20 trades open, 1 negative, while  the Live has 19 open with 10...
Hi, I'm trying to write a simple rsi EA code for mt4 but my code is working just part time . ClosePosition function is not working.( probably my code is a bit weirdo lol ) .

Hello, I used (there these years +) the Play-sound function in MT4 progs without problems Today I want to utilize this function again but there is no sound emitted even though the file is found: 10/26/2015 checked this in the program with the following code: PlaySound("bidonalert.wav");...
Under Build 902, Custom indicators are no longer removed automatically, if not used for 10 minutes. This, I think, partially contributed to the result differences between live accounts and Strategy Tester. Strategy Tester never removes indicators - at least I didn't see any indications to that. I...

I see other platforms that offer a wide range of hourly candles, not just 1 & 4 hr. & daily....  One I saw offered 1-12 hr. + daily,...  It is very instructive and helpful for interpreting candle setups.  Surely, given the open format of MT4 there are add-ons that provide this? I appreciate your...

You can find my function below. i wrote this for detecting crossing a level. when i want to use it...
Dear all, I'm puzzled with how to track partial closes in MT4 account history when multiple EAs are running on the same account, and more than one of them are doing partial closes. What I see in the comment field instead of the EA name is something like from '#24048391' or' to #24062061'.  Even...

I now have the following to complete:...

I indeed need everyone to support to develope MT4 to send mail to others through Gmail or Yahoo mail or Zing mail. Very many of sincere thanks!
I've got a bunch of indis I wrote, not recompiled since my MT4 auto updated to 890, all working fine. I needed to make some minor changes today, and recompiled against 890, and suddenly strange things are happening. For one, an ArrayResize statement in a section of code is now completely failing to...

Hello, I want my indicator to execute an order but I know that is only possible by a script or EA. I don't want to use an EA here and therefore the only possibility is to use a script and I read that the only method to execute a script from an indicator is by simulating a hotkey-keystroke which...
I download FX Blue QuickChannel library, seems it can make OnTick called whenever a new message is sent, from a DLL (indeed from another process). in QuickChannel pdf document, it says, ============= Once an EA/script has called QC_StartReceiver(), it receives a tick whenever a new message is...
Hi forum, I want a vertical line to be drawn if I press (and hold) the s-key and click on a candle. But that doesn't work the way I tried it. I know that this is not correct because there can't be a CHARTEVENT_KEYDOWN and a CHARTEVENT_CLICK at the same time. But how can I check if the s-key was and...

Hi, I've developed Corona Charts by J.Ehlers for MT4. You can find their description here. Regards, Igor
(Please, some patience because I just started in MQL.) On the chart I put an OBJ_BITMAP_LABEL, which has two states: on and off. When I click the image changes (img1 in img2 or img2 in img1), and so on. But the key-thing for me is: how to launch a script when I click? I searched the internet but I...
