      Hello SaveO, here is my screen shot. I am still wondering why it is not showing arrow. Thank you for your time and effort.

        This is how my screen looks before and after i attached the Fractals Arrow Indicator. There is communication between MT4 and mysql. My database is populated.
        But no Fractal Arrow is showing on my screen.

          Can you please show me a screenshot of the Node.js app right after you start it up again. This should be after the data is already in the database. Once your database is loaded, there is no need to populate it again. Then just attach the indicator with load_data set to false to test for arrows anytime after the end_time.

            Hi SaverO, Thank you very much. My mistake was not turning the load_data set to false after loading the database.
            Here is the screenshot of Node.js and my chat with arrow. Thanks :good:

              Awesome! Now just need to tweak the logic to make it work :-)

              You may need to adjust things on both ends (node.js app and MT4 code).

                  Hi Saver0,

                  I hope you are still supporting this. Really impressing framework.

                  I am trying to install this under Windows 10. Everything went smooth, to the point where I should call “node fractal_server.js” (5d). This gives me the error message, that it can’t find module underscore. I am sure I did install it per your instructions and I could even locate it on my hard disk. I tried to add the path of it to the system path (an rebooted), but this didn’t help.

                  Any idea what might be wrong?

                  Thanks
                  Mecki

                    Hello,

                    You may try to copy “C:\Users\profile\yourname\Roaming\npm\node_modules” directory to the Node installation directory. And you should install Node outside of “Program files” directory (and “Program Files (x86)” as well).

                      Hi Moon,

                      thank you for your help. It brought me one step further but not through. Please see below for the error message I am getting now.

                      Thanks

                        C:\Node\fractal_server.js:891 connection.query(selectString, function(err, rows)

                         

                        Now it’s simple Node works well but mysql server doesn’t work (or is blocked by firewall – make sure that is properly running on port 3306) or Node connection is blocked by firewall (or antivirus).

                          Aeeh, Hi, me again. It’s starting to get embarrassing.
                          Ok, node runs now fine, I downloaded tickstory and EURUSD tick data for the recommended time interval and exported it to MT4. As a result of this a bunch of HST files were copied to a directory C:\Users\MelanieandMarkus\AppData\Roaming\MetaQuotes\Terminal\3212703ED955F10C7534BE8497B221F4\history\OANDA-GMT-5 Practice and another bunch of FXT files were copied to a directory C:\Users\MelanieandMarkus\AppData\Roaming\MetaQuotes\Terminal\3212703ED955F10C7534BE8497B221F4\tester\history. The HST folder already had other HST files, the FXT folder only contains the files which were copied by tickstory.

                          The problem is, that no matter what I do, I don’t get a EURUSD M15 chart on MT4 which goes back to a time before 2013.

                          Thanks again,
                          Mecki

                            OK, take that back. It is a problem between my MT4 built and the tickstory version. Obviously version 1.5.3 does not work with built 950. I guess I need to invest 30 bucks and get version 1.7.4.
