How to avoid OrderSend Error 130 in MT4

If EA is running, you may receive an error”
OrderSend Error 130 “.

”
OrderSend Error 130 “is because the constant is”
ERR_INVALID_STOPS “(= invalid loss stops) in the following cases.

Reason # 1: Loss cutting (profit fixing) prices are too close to current price data.

Reason 2: The formula used to calculate the profit and loss reduction (profit determination) price is incorrect.

Reason 3: Loss reduction (profit determination) prices have not normalized.

the reasons for the occurrence of “OrderSend Error 130” are described above, but the first reason may be the cause of Error in particular, so the possibility is relatively low.

we checked to avoid cause 2 and 3, so we could basically avoid the Error “OrderSend Error 130”.

Linux mounting errors (Error mounting /dev/sda8 at /media)

Mount an NTFS partition that cannot be accessed from Windows under Linux
About Windows 7, the computer installed Ubantu in the other partition (not allocated space under Win7). After installing Ubuntu, the user was not allowed to access the Windows 7 partitions by myself. Error mounting /dev/sda8 at /media/my/XXX: commandline ‘mount-t “ntFs-o” was not allowed
Solution:

Open terminal: If ntFS-3G is not installed, sudo Apt-get install NTFS-3G

Fix the appropriate partition for mounting errors such as /dev/sda8 in the prompt, enter:
sudo ntfsfix /dev/sda8
Just hit enter.

Rstudio drawing problem

“‘
Error in RStudioGD() :

two days appear this problem, because before the computer with two versions of the R, appears the question, said online because Rstudio cannot identify, unload the unused version, later. This problem appears again today, I do not know what the reason is, it is OK to uninstall and reinstall.

brew link sip error

Problems with BREW installing SIP:

$ brew install sip
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink include/sip.h
/usr/local/include is not writable.

You can try again using:
  brew link sip

Golang Docker Build runs an error after making the input
The problem arises because the environment in which you are compiling is different from the environment in which you are running, and may have dependencies on dynamic libraries
1. By default, go USES static linking and dynamic compilation is used in Docker’s Golang environment.
2. If you want to compile +alpine to deploy with docker, you can do so by disabling cgoCGO_ENABLED=0.
3. If you want to use cgo, make GCC statically compiled by go build --ldflags "-extldflags -static".

R language loading xlsx error error: JAVA_HOME cannot be determined from the Registry

OnLoad failed for ‘XLSX’ :
loadNamespace() calculate ‘rJava’; onLoad failed,
call: fun(libname, pkgname)
error: JAVA_HOME cannot be determined from the Registry
This is because my computer is not installed the JAVA environment, right now I need to download and install the JDK, website download address: https://www.oracle.com/java/technologies/javase-downloads.html, the website need to register account and download speed is slow, there are baidu network location 64 downloads: link: https://pan.baidu.com/s/1WQvo3UyVPtBypGcCLLCLzQ extracted code: wg5o
After downloading, which contains the method to install the JDK, introduce a public number, commonly used in all kinds of software download source and installation methods ~
After installing the JDK, first find the location of R installation package. Generally in the library document under R-4.0.2, delete the packages that were not installed successfully before. Here, I will delete RJava, Xlsxjars, and XLSX

After you delete it, go back to the Rstudio window and install it in the order rJava, XlsXJars, and XLSX. There are two ways to install the Package of R, either way
Method 1: Run the script
Install. Packages (” rJava “)
install. Packages (” xlsxjars “)
install. Packages (” XLSX “)
Method 2:


After installing library(XLSX), there will be no errors!!

emulator: ERROR: x86 emulation currently requires hardware acceleration! Abnormal problem solved

Start this exception after the AS configuration simulator:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Because you need an Intel hardware Accelerator, check the three steps
1, check the Intel x86 Emulator Accelerator(HAXM installer) in SDK Tools is installed;

Go to the SDK \ Extras \ Intel \Hardware_Accelerated_Execution_Manager folder and double-click to install Intel HaXm-Android.exe.
if the installation is successful, just go to AS to reinstall the emulator.

Ubuntu fixes the missing dependency packages of the system (Error: Broken Count>0)

If ubuntu has a package that does not meet the dependency criteria, Error is reported :Broken Count> 0, as shown below:

The following command will automatically fix the packages on which the installation package depends:

    $ sudo apt-get install -f

The -f parameter stands for Fix Broken.
If the fix fails and there is still a problem, confirm which application was installed earlier and then execute the following command to uninstall:

    $ apt remove xxx

After the unloading is completed, it is found that no error is reported. The figure is as follows:

Ubuntu fixes the system’s missing dependency package to this solution.

Tomcat9 Error: Could not find or load main class org.apache.catalina.startup.Bootstrap

First I login is tomcat website, select the source package download, wget HTTP:// http://apache.fayea.com/tomcat/tomcat-9/v9.0.0.M26/src/apache-tomcat-9.0.0.M26-src.tar.gz

I feel very strange, first check the/MNT/tomcat/bin/bootstrap jar does not exist, and then use the find/-name the bootstrap. The jar can’t find it in the local. So where does that come from?
 
After looking at the post on the Internet, I realized that the source package in the official website of Tomcat was incomplete. The logs folder and some important files of bootstrap.jar were not available. The correct Tomcat should download its bin package

Write it down so you don’t waste time checking your journal!

Cannot find module ‘body-parser’

bug:Cannot find module ‘body-parser’
For obvious reasons, this module isn’t available, and if you look in the node_modules directory, it isn’t

Solution: Reinstall the module;
CMD switch to node installation directory:

npm install --save body-parser

​​​​​​​(Copy python package, the problem generated) pip Fatal error in launcher: Unable to create process using

Today I cut the Python installation from disk C to disk D,
The corresponding disk character in the Path environment variable is then modified: D:\Python27\; D:\Python27\Scripts;
In either directory, Python is ready to execute, but Pip is an error!
D:\Python27\Scripts> PIP
Fatal error in launcher: incapable of creating process using ‘”C:\Python27\python.exe
“”D:\Python27\Scripts\pip.exe” ‘

The Path environment variable has been changed, and I’m surprised that it’s still looking for the C disk.
It’s ok to try “Python PIp.exe install”, but it’s a bit of a hassle to use, so you want to figure it out! I don’t want to reinstall it!
A web search for “where did PIP read the Python installation directory from?” failed, and an error message was found!
Some netizens in CMD under the implementation of “Python-M PIP install — Upgrade PIP” to solve the problem, I this is not.

Oh, I didn’t add the -m parameter.
My solution, which is a little more barbaric, is to use the binary editing tool “pip.exe,”
Reference: http://stackoverflow.com/questions/24627525/fatal-error-in-launcher-unable-to-create-process-using-c-program-files-x86
Open with HEdit, search for “C:\”, find the corresponding location, change the disk to “D”, save, and then execute the “PIP” command.

There are multiple files in the “D:\Python27\Scripts” directory that do this, so it’s easy to change them.
