The file I have attached works for me. I essentially tell it to wait a certain number of ticks (default set to 5) after init/restart before running the full export. I don't know why it works since I tried a lot of other ways to no avail. I think there is either a bug associated with FileOpen/FileClose or there is something about how it works that is not specifically described/documented but I am no expert.

You can implement what I did and erase the debug variables I included if you wish. However, I'm a big fan of using DebugView with MQL4 so if you don't use it already, I encourage you to take a closer look.

I'm sorry, but after the changes described above the indicator works at the start of MT4, but it no longer refreshes the exported file. The reason, I suppose, is the code in point 4) should initiate that refresh process at the completion of the tfr bar and here it does nothing - no call to the Export() function, as there is no Export() function after I removed the void block. After many experiments with this code I have noticed that just doing without the 'void' structure and leaving that code in start() makes it start at the software opening and...

Thank you very much, Aim! Yeah, you've made it work! What you've done way exceeded my expectations, so many thanks again! I didn't think of the funny tick countdown, but it seems to play a key role in your solution. :-) I like it, although, I'd rather not have it going after every change of time frame. You've also trimmed the figures to three decimal places, which is very reasonable. I only wonder, if the decimals are properly limited (according to the rules of statistical precision, like in the NormalizeDouble()) or are they simply cut to the third digit after the point? But overall, it works fabulously and I still explore the code within, as I'm not an IT developer, but just a trader, who wants to automate some manual work. I will check out DebugView, because I've never used it.

This tickdata collector (indicator) will create a new .csv file everyday and constantly updates it, there is also a readme file for some advice and etc. - This indicator is downloaded from Armada Markets.

But when you open the .csv document, Metatrader 4 cannot update the contents of this opened file, so always copy paste this file to another location. - I am confident that the same rule will apply for all the EA-s or indicators which modify files.

As far as the statistical precision, it appears DoubleToStr vs NormalizeDouble has the same precision up to 8 decimals when I compare them. However, I don't know that from any other source than my own testing so please check for yourself. Since the number of decimals is an external variable, you can set it to whatever you want if you need more than 3 decimals in your data.

As far as DebugView, check out the thread started with 7bit a few years ago. It should get you started. http://www.forexfactory.com/showthread.php?t=245303

Do you arbitrarily change time frames or do you always go through a certain set e.g. M30, H1, H4 etc to export data for each? If you always go through a certain set, why don't you set up an array with each of them like you did with Pair_Name[], loop through each of them and have the output file name be Outputfile + timeframe?

So I'm OK with DoubleToStr and the decimal precision you've set, Aim. A very good job!
Yeah, I've already found that thread and I'm going to explore it, when I have more spare time.
I export only the data for H4 to my 'control centre' in Excel - that's where I manage the fx markets and build my database for further analysis. Currently I can't think of any use of other time frames other than for the charting and trading purposes. So H4 will certainly do for me. But I see your point - sure, if I needed to export the data for several time frames, a loop through each of them would be an indispensible solution here.

Glad you find it useful. Based on your comment "I'd rather not have it going after every change of time frame" I thought you were changing the time frame parameter (by default set to 240) to get new values. Otherwise I didn't see a need to change the time frame at all, so the indicator would just keep running. For indicators/EAs like this, I just keep the in a separate chart so they don't interfere with my "trading" charts where have my trading EAs running.

FYI, I am "just a trader" too looking to automate as much as possible. Turns out, writing the code is the easy part...

Dear hanover,

Could you update your indicator (Output History), which would be suitable for new MT4?

Thank You in advance.

MetaQuotes assure us that .ex4 files that ran correctly on build 509 will continue to do so on build 600 onward. Simply copy the .ex4 file to the new location, NOT the .mq4 file. This video by CompassFX explains how.

I can not update the .mq4 program code, because I’m not fully conversant with the new programming language. Hence I won't be updating any of my indicators or EAs, or undertaking any more MT4 programming projects. If you really need the .mq4 file, you could try posting your request in one of the "I code your indicators for free" threads.

I'm no expert, but you've put zero as 'int shift', whereas you probably wanted to put an 'i'.
Try this: iATR(NULL, PERIOD_D1, 14,i).

I think you mean "indicator value". You can do it - every minute - with my file (working thanks to superb modification by AimHigher, please find enclosed my v.4). But every tick? I don't know; perhaps there is a way to do it?
