MT4 70 TickChart Script Version

:::Overview:::

png
70tickchart with BollingerBand and Volume

I made 70 tick chart of script version. (see. our Indicator version 70tick20ema.mqh)
Since the original include file is partially modified, it is necessary to replace these files;”Files/FileBin.mqh,Files/File.mqh”.
‘BV’s 1pip unit display’ is made possible. Spread cancellation is also implemented.
In this script, Struct MqlRate including ‘spread’ is filled with 0, and ‘real_volume’ is used for recording ‘tick interval(seconds).
I recommend 5 minute chart to attach as source of this script. Since data interpolation is performed, the deviation from the actual chart becomes large when the time frame is longer than that.

:::Usage:::
1 Attach this script to a M5 or M1 online chart.
2 Open offline history file from menu(file-offlinechart- see ‘T’suffics file).
3 If the offline chart was not change automatically, attach this script to previous online chart again.
4 Attach any indicator you like to offline chart.

:::Recommended Indicators to be used with the offline chart:::
“Volume” indicator will be recommended so that helps you see the tick completion displayed in red turn to green at a glance.
To display 20 EMA, the indicator “Moving Average” or “Bollinger Bands” should be used.

:::In development:::
It seems that it is possible to substitute existing on the range indication etc. which had been created with the indicator version. Independent indicator for supporting BobVolman’s method is under development.

ver1.01 1pip-unit displayable.
ver1.02 Tick and Bars Speed displayable.

How to use Metatrader4 on affordable VPS

For example, VPS(KVM) by onamae.com

bibliography
    lubuntu http://lubuntu.net/
    WINE https://www.winehq.org/
    MetaTrader4 http://www.metatrader4.com/
    ONAMAE.COM http://www.onamae.com/

0  VPS contract and login
I made an MetaTrader4 platform on the virtual private server(VPS-KVM) provided by “ONAMAE.com”.
This server has such specs below;
-CPU : shared virtual Core2DuoT7700 2.4Ghz
-MEMORY : 1GB
-STORAGE : HDD 20GB + 80GB
-RENDERER : Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)

You can jump to “onamae.com” web site, and make a contract of smallest size VPS(KVM) that has memory size 1GB.  Don’t select any bigger one.  You don’t need higher spec over 2GB memory for this aim, in this case to install and run the MetaTrader4 and some related programs.
Then you can get “Login ID” and “Password” of your VPS, go to the login page “https://cp.myvps.jp/”, and start your control panel.
Click the VPS name field (for example “kvm00XXXXXX”).

2016-05-13-3-1

 

1  Installation of Operating System and some others
Next, you have to install Operating System, desktop manager, and WINE Windows(R) compatibility layer program.
I would recommend “lubuntu” the lighter version of “Ubuntu”.
The reasons are ;
– Light weight action and less memory use
– Support the Ubuntu kernel and WINE package.
Well, Let’s start installation processes.

1) First, you have to visit “lubuntu” web site, and download the latest “-.iso” image file. Do not download Japanese localized version, since save memory. In this case, you cannot use Japanese IME at your VPS.
2) Then, enter userID and password to open the control panel of your VPS,

2016-05-13 (7)
STEP1 Make SSH connect

3) The “-.iso” file previously downloaded must be inserted to the special “image” folder of common server at ONAMAE.COM. You can use “WinSCP(SFTP software for Windows)“. If you are using the other Operating System, you can use your SFTP client suited your OS).
4) At your WinSCP, Select “New Site” > SFTP , and fill Host name > User name > Password.

2016-05-13-6
WinSCP login

And you have to hit the “Settings” button. You can find SSH > “Permission” at menu tree on the left, Select “Secret Key” from file already downloaded. You will find a notification saying some cautions. You have to create and save a “private key” as .ppk format. After you saved that key, you should select again the saved key(-.ppk not -.key), and press login button on the WinSCP.

2016-05-13-5
key to ppk

5) After copying iso image into server, You have to go back to server control panel. Click the server listing area “kvm/////”, press the “please select image” drop-box, scroll down , choose “[kvm///]lubuntu///]”, hit “insert” button, then click “restart” button.

Control panel load the iso data, and prepare install menu. Follow the instructions of installer. Nothing will be bothering you while the installing process.
The installer show a restart order on-screen. You have to remove force the iso image. After that, hit the “restart” button again.
If you complete process, the lubuntu desktop will appear on-screen.  Resolution can be changed from menu > Preferences > Monitor Settings.
Are you ready?
So, Let’s go next step.

2  OS initialization
Next, You would install WINE.
The site “https://wiki.winehq.org/Ubuntu” will help you well.
1) Login Control panel, and start server.
2) Start 32bit architecture
sudo dpkg –add-architecture i386
3) Add repository for wine
sudo add-apt-repository ppa:wine/wine-builds
4) Update for packages
sudo apt-get update
5) Install WINE developer version (latest 1.9)
sudo apt-get install –install-recommends winehq-devel

*Notice: Stable version 1.8 have some trouble with winhttp, so MetaTrader4 installer will lost network connectivity, and may cause of install failure(so-called “proxy problem”).
WINE installer help you when you need to install other necessary program. Please obey their suggestions.

6) Visit MetaTrader4 download page (anywhere you like) ,download, and  save the .exe file.
7) Start Filer, and open the metatrader.exe by Wine program loader. Install  process will begin.

That’s all for installation. Try metatrader4 on your VPS.
If you have original Expert Adviser or Indicator etc already, it would be better to install SSH and FTP server on your VPS. Let’s try final step.

3 Server settings for management
If you need to handle your VPS with remote, these applications below must be helpful to save your time.
1) OpenSSH
sudo apt-get install openssh-serve
*It’s easy! However, it may cause security problem, so you must install   firewall.
I recommend “WinSCP” as client for Windows.

There is one difference between .iso loading process and after OS installed.
If you installed OS from your own uploaded .iso file, you don’t have to hit the “Settings” button. You could find SSH > “Permission” at menu tree on the left. However, You can connect by password, so you don’t need download the “Secret Key”.

One caution is that password authentication includes security risks. So you must install Firewall on your server and close port, while you don’t handle remote file handling.

2) Vsftp
sudo apt-get install vsftpd
*It have also security risk, so you must install firewall.
I recommend “TeraTerm” as client for Windows.

3) Firewall GUI (*VERY IMPORTANT!)
sudo apt-get install gufw
* When you don’t need remote file handle, It would be better to set the  firewall “on”.

That’s all from me.
If you need more information, please search from internet resources.

70tick20EMA indicator for MetaTrader4

70tick20ema & MyCPanel

The original program was developed by Mr.Rondo(http://fx-dollaryen.seesaa.net/article/414537690.html).

Remodeling contents by me are below:
Rounding price for the candle bar to be displayed in the 1pip unit
Adding horizontal lines to be displayed change at the time of the appearance of the DD sign
Adding horizontal lines to support range imaging
Adding a control panel to change or reset the number of DD and Range settings.

Installation:
1. Download 70tick20ema.mq4 and myCPanel.mqh.
2. Put the *.mq4 file to ‘Indicator’ directory , and Put the *.mqh file to ‘Include’ directory.
3. Compile mq4 file in MetaEditor.
4. Let’s try on your chart.

Usage:
Please try in various usage.
When the display becomes strange, turn off the chart, and try to re-display.

Option notice:
‘Ignore spread true’ means absorb the spreads variable. when it is false, bar price is displayed as supplied price by your fx broker.

Please download here(ZIP file) >> 70tick20ema.zip

Thank you.

http://www.green.dti.ne.jp/sdimension/mql/mql_2011_03.pdf#search=’mql+dll’ Mr.amenbo Helpful document with 4step development method
https://www.tradersquare.jp/community/topic/47-mt4-%E5%90%91%E3%81%91-dll-%E3%81%AE%E9%96%A2%E6%95%B0%E3%82%A8%E3%82%AF%E3%82%B9%E3%83%9D%E3%83%BC%E3%83%88/ Document about MQL4 and DLL export table

Test fo file handling and string transition

I chose the 4 step method suggested by Mr.amenbo(see link), and add a bit shortcut.
The step 1 is same as original idea, so let’s begin.
I wrote ‘test.cpp’ as my solution name, but you can change as you like, within coding regulations.
‘%…%’ mean replace proper string.
Many impressive site are exist, but difficult for beginners. My comments in the .cpp code below might be helpful for your .dll coding for MQL4. Because I spend huge hours to understand how to call dll from MQL4. If you like this message, please give me your expected expenses.
You may try this code at a debug mode. Push ‘local debugger’ and you can see a console window and prompt on the window.
Here, step 1 must be complete, easy? or difficult?
If you have question, please comment to this message. I don’t receive any e-mail from unknown person.
Finally some important notices, I cannot speak english, as you know?… and I’m a native japanese living in Japan.

Step 1-1 Create full code on C++

// test.cpp : Test for Console application for MT4
#include "stdafx.h" // you need add other header below in this headerfile
// #include "targetver.h"
// #include <tchar.h>
// #include <locale>
// #include <string>
// #include <fstream>
// #include <iostream>
// #include <stdexcept>
// #include <limits>
#if defined(_UNICODE) || defined(UNICODE)
# define tcout std::wcout
# define tcin std::wcin
#else
# define tcout std::cout
# define tcin std::cin
#endif

typedef std::basic_string<_TCHAR> tstring;
typedef std::basic_ifstream<_TCHAR> tifstream; // file in stream
typedef std::basic_stringstream<_TCHAR> tstringstream; // string in stream

_TINT no; //Just for debugging

_TCHAR* hello(_TCHAR *file_name); //prototype statement

_TINT _tmain(_TINT argc, _TCHAR* argv[]){
    _tsetlocale(LC_ALL, _T("ja-JP")); //locale is important, don't forget

    _TCHAR file_name[] = _T("% fullpath and filename here %");
    tcout << hello(file_name);
    tcin >> no; // test use only, just for prevent close console window
    return 0;
}
//+---------- function-------------------------------------------+
_TCHAR* hello(_TCHAR *file_name){
// return and pass is both 'char pointer', it's important
tstring s; // string
tstring ss; // if you need formatted string, you can use 'tstringstream'
FILE *fs;
errno_t err;
err= _tfopen_s(&fs, file_name, _T("rt, ccs=UNICODE"));

// open err
if (err != 0){
    return _T("fail not open that file"); //takecare, file exist?
}
else{
    // success open file
    tifstream ifs(fs); // make a filestream
    while (ifs >> s){ // you don't need use 'getline' method
        ss += s; // just for string case. if you want to use stream...
        // ss << s; // like this.
}
tcout << ss; //just for this test, strip this line when you copy to dll code.
_TCHAR out[1000]; //no intention this number, not too short and not too much
err = _tcscpy_s(out, 1000, ss.c_str()); //also above
if (err == 0){
    static _TCHAR *outp = out; //keep address for MQL4
    return outp;
}
    else return _T("copy fail");
}
}

Step1-2 Create MQL side code

This is an alternate method on Mr.amenbo’s.
The interface of mql and dll is quite easy. if you put ‘string’ to dll, the mql send that as a pointer to that string to dll. Dll receive as it, and then return pointer, and the mql take that as string with pointer. So you don’t need create ‘call program’ as step3 in the Mr.amenbo’s method.
And there is one tip, ‘Alert’ method in mql do not work well, that title is ok, but contents may fail to draw proper character.
If you can correct that problem, please tell me how to do that.
Partially, I choose the ‘MessageBoxW’ with windows API, imported by WinUser32.mqh.

    int i=1;
    long search_handle=FileFindFirst(InpFilter,file_name);
    if(search_handle!=INVALID_HANDLE){
    do{
        ResetLastError();
        FileIsExist(file_name);
        //PrintFormat("%d : %s name = %s",i,GetLastError()==5018 ? "Directory" : "File",file_name); //just for debug
        i++;
    }while(FileFindNext(search_handle,file_name));
    //--- executional code ---
    string terminal_data_path=TerminalInfoString(TERMINAL_DATA_PATH); //search install path
    file_name=terminal_data_path+"\\MQL4\\Files\\"+file_name; //test pattern
    //--- close search handle
    //PrintFormat("fullpath in MQL4: %s",file_name); //just for debug
    string ret=hello2(file_name);
    int flg=MB_ICONINFORMATION+MB_TOPMOST;
    MessageBoxW(0,ret,ret,flg); //I cannot solve the 'alert' problem, so I use a windowsAPI on user32.dll, see header file
    //Alert(ret); //You may see an error with character code problem
    FileFindClose(search_handle);
    }
    else Print("Files not found");
}

Step2 Create dll code

Important note is just below;
1) #define MT4_EXPFUNC __declspec(dllexport)
2) __stdcall
That is it.

1) Copy the header and target function code from full code create above.
//+———- function——————————————-+
_TCHAR* hello(_TCHAR *file_name){……

2) Change that title of target function to below.
MT4_EXPFUNC _TCHAR* __stdcall hello(_TCHAR *file_name){……

3 Set build mode to ‘Release’, and select menu project>property>, and set ‘Structure Property>c++>code create-runtime library’ to ‘multiple sleds(/MT)’.

4 Build it.

You don’t need to create module definition (.def) file. (at least on VC++2013 ? I’m not sure in facto… Please tell me genius wizard)

Step3 Test!!

Did you make it?
If you missed it, let’s work harder. Please leave a message to this article.
