Hi folks,

I have started this thread because I am having a serious look at MT5. Having searched for clues on how to drive this beast and found most of what I want, I am still left with one problem as described below. I like the MT5 mainly for the different TF's, but the MT4 indics dont all go into it !?

Anyway, what I would like at the moment is for someone to point me in the correct direction on where to install a "MQL Header File". This has me totally lost.

Tnx to all who respond ....

what do you mean by a Header File?

He probably thinks of mqh files. They then go to MQL5\Include or even MQL5\Include\Expert?

If you open metaeditor and choose to make a new header file, it goes to MQL5\Include; so I would put such files there.

Tnx MaxDoom and Rockit,

I have been fixing up a few bugs in my PC, hence the delay in getting back to you, my apologies.

In MT4 it is clear that the mqh files go into the Include folder inside the Experts folder. The situation in MT5 is not quite as clear. We go to: MT5>MQL5>Include> and I think it is "Files", but there are 8 other folders inside the Include folder. Now, inside the "Files" folder I have detail as shown in Pic 1 which is where I got the "MQL Header File" title. Pic 2 suggests that mqh files belong here but the associated indicator doesn't work, so I conclude I have got mqh in the wrong place !?

More study on my part I think .... Tnx guys.

do not worry about the other folders in there just put your includes in:

..../MQL5/Include

and then when you reference them use this format

#include <TradeCode.mqh>

the "<>" tell the compiler that the files are in the include directory


that is the easy bit, but are you even using the right file structure MT5 has a duplicate file structure buried deep inside the users file structure

...users\username\AppData\Roaming\MetaQuotes\Terminal\ADSADASD78ASD78FAS8FS

which is used by default. you can avoid having to place all your files here by changing the command line that starts the MT5 terminal to include the following flag:

/portable

this tells MT5 to use the installed directory for everything

Tnx MaxDoom,
RE:"do not worry about the other folders in there just put your includes in:
..../MQL5/Include
and then when you reference them use this format
#include <TradeCode.mqh>"

So, do I understand you correctly in that I type the "<>" on each side of the TradeCode.mqh, instead of simply placing the thing into the "..../Include" folder ?? ( I did have the mqh file in "Files", obviously I got that wrong )

As for the last part of your post, I am afraid I am totally lost with that. It seems to me that installing MT5 would sort that out itself ??? I did a Start>search "AppData" and got a list showing a bunch of AppData entries with mainly "....Roaming\Thunderbird\...." but no "....Roaming\Metaquotes\...." ?

I am beginning to think I must abandon MT5 .... perhaps I am too steeped in MT4 ?

yes, if it is enclosed in <> then it will search the include folder see here: http://www.mql5.com/en/docs/basis/preprosessor/include

your dream of going back to MT4 will hit the same problem as they have now updated the MT4 file structure to match that of MT5.

You need to decide if you want to work with the deeply hidden MT5 folder structure in the users area or if you want all your MT5 files to be in once place under the installed MT5 folder. I use the latter by including the /portable flag
