Hangover, I couldn't find .....experts\scripts folder, but I found .....MQL4\scripts folder. Therefore, I copied your code into that file. Then, I tried to adjust the heading section and FileWrite section of your code as it is below.

FileWrite(handle,"Date,Time,Open,High,Low,Close,Volume,MACD");

FileWrite(handle, date1, time1, iOpen(ccy,tf,i), iHigh(ccy,tf,i), iLow(ccy,tf,i), iClose(ccy,tf,i), iVolume(ccy,tf,i), iMACD(ccy,tf,12,26,9,PRICE_CLOSE,MODE_MAIN,i));

Then, I recompiled it, and dragged to gdpusd daily graph. And then, I exported the history from the history center, but I didn't see MACD values on my excel sheet. Therefore, where did I make mistake?

The script probably doesn't compile in build 6xx. Hence copy the .ex4 file only (do not attempt to modify the .mq4 code).

@Mertimiks: Use the old build 509 compiler, compile the file and copy the .ex4 ONLY in the right directory of you mt4 installation. that should work.
See my thread (how to compile old mql files), download the editor (.zip, just extract and use, size ~2.2 mb): http://www.forexfactory.com/attachme...6&d=1397124670 ...

Hanover, I did the adjustment to your code to add MACD, because I wanted the MACD results along with historical data and your original code does not include the other indicators. In the future, I want to add as many indicators as I can.

Could you answer me the followings:
1- Why I do not have a directory as experts\scripts, but I have scripts and experts files are located in the same folder which is MQL4? And how can I fix that?
2- From what you said, I understood that there are two compiler types, and I have build 6xx instead of build 509. So, can you guys show me how I can go back to build 509?

MetaQuotes have changed the folder structure. You might be able to use the /portable switch to retain the old structure. I haven't tested it; you could try FF's search facility or Google for more info on how to use it.

However, as long as you copy your .ex4 files to the correct folders, there shouldn't be a problem. Use MT4's 'File >> Open Data Folder' option to find the location of the MQL4 folder. Then:

  1. EAs go in the Experts folder
  2. indicators in the Indicators folder
  3. scripts in the Scripts folder
  4. include files in the Include folder
  5. support files go in the Files folder
  6. templates go in the templates folder that's on the same level as the MQL4 folder

I quit MQL4 programming when I found I wasn't able to return to the 509 platform. However, if you have a backup copy of MT4 509, it might be possible to restore it, and then somehow block MetaQuotes' future attempts to force upgrades to 6xx. But when MetaQuotes finally switch off the order entry, live price feed etc for 509, it will no longer be usable.

Nonetheless, for as long as ex4 files compiled in 509 continue to run in 6xx, it should be possible to edit/compile in 509 and then test in 6xx. Fxdaytrader explains how to do this here. Back in February I posted something similar here, but I'm not sure how well this works any more. You might also be able to find answers in this thread.

Sorry I can't help further, but I'm totally fed up with all of the problems created by MetaQuotes and MT4.

Okay, today I found out that you can simply export indicator data from fxcm trading station. After you apply the indicator, you simply go to file, and export to excel, and you have all the values.

{quote} Ignacio, I assume that you mean you want to output the value of an indicator to a text file, instead of Open, High, Low, Close, Volume, etc? If so, it can be done, but you need to write a script. The one that's attached will do it, but you need to add to the FileWrite statement, to tell it which indicators (and their parameters - e.g. MACD(12,26,9)) that you want it to output. See the comments in the script for more info. Instructions: 1. Copy the attached file to your .....experts\scripts folder. 2. From MT4, press F4 to load MetaEditor,...

Thank you for sharing
everything went fine for MACD, but when I've tried my custom Indicator, all records were 2147483647 - I assume something went wrong
Is it possible to use the script for custom indicators?
If yes is there a different way to make it happen?
this is the line I've used

FileWrite(handle, date1, time1, iMACD(ccy,tf,12,26,9,PRICE_CLOSE,MODE_MAIN,i) , iCustom(NULL, PERIOD_CURRENT, "Name of the Custom Indicator", 145, 700, 144*2, 144*3, 144*4, 0, 1) );

have a nice time

I've figured it out

this is the line that works
iCustom(ccy,tf, "Name of the Custom Indicator", 145, 700, 144*2, 144*3, 144*4, 0, i )
I think that "2147483647 " is just a kind of empty value

I don't know of any reason as the code (at least in the attached version) includes no explicit limitation.

I compiled and ran the attached version of the script, dragged it on to the GBPUSD,M15 chart, and got the attached output (41,580 bars).
___________________
[EDIT] More info on this script here.

Also, please note that it was written before MQL4 build 600 (released in Feb 2014), hence if you want to modify and recompile, you'll need to use the build 509 compiler, more info here (and also this thread, and here, here, here).

I have no idea what that does?

3000 bars of what? 1-minute, Monthly chart?

How do you know that is an issue?

Can you post a picture?

Not much help sorry.

Sorry, I assumed you were using the script attached to post #6. I haven't seen Plot External Data_2 before, but it appears that there's a limitation in lines 16-18 of the code:

datetime dt[29999]; //Array to store the Data & Time
double val1[29999]; //Array to store the value of Column1
double val2[29999]; //Array to store the value of Column1

You might need to increase the sizes of these arrays and recompile.

Sorry
I simply posted in the wrong window, since I was using your output code to feed a plot

and I'm very grateful you took the time to show me the problem

Many, many thanks
