I'm stuck on a problem with my custom symbol code in MT5 - General

fxsaber 2021.04.20 11:21 #301

Is there some mechanism to be able to share a hundred custom characters with someone else?

History is easy to transfer - just copying the Custom folder. But the character specifications are unclear.

I have to write custom script to upload/download them. I wouldn't wait for regular export/import.

Andrey Khatimlianskii:

A self-written upload/download script is called for. I wouldn't wait for a regular export/import script.

It takes a lot of effort, even though it seems simple at first glance. You need to know the correct sequence of setting symbol properties. Plus, there are troubles with quoting/trading sessions.

I.e. it takes a lot of work to debug and debug.

I have attached the dependency file.

I am getting this error:

Please help me find the problem and what exactly I need to do to make it work properly.

The error means that I am not filling in the checkboxes on the structure. But if this is the case, how did the previous candles look perfect?

Opened the terminal today, downloaded update 2994, MT5 rebooted. I see all the symbols are gone, including many custom symbols.

In the bases\Custom folder I still have history and ticks folders with .hc, .hcc, .tkc data files for custom symbols, how can I use them now?

Warning! Do I really need to re-create custom symbols, import history etc.??

You could try moving the Custom folder to another location and re-creating the symbols - specs, no history. Then quit the Terminal, copy back the Custom folder and start the Terminal. History should pick up.

Backup of json-character settings on Terminal side is called for. Accidental deletion or other nastiness - restore from backup.

It worked. Thanks for the time saved!

Custom Sybmol: ERROR 5308

Dark Ride3r, 2021.06.24 09:55

I am trying to set SYMBOL_VOLUME_MIN for a custom symbol but it returns ERROR 5308

I completely checked that the other parameters work fine, but only SYMBOL_VOLUME_MIN, for which I set it as double, returning

ERR_CUSTOM_SYMBOL_PARAMETER_ERROR 5308

so I think this is an error in the system and needs to be reported so it can be fixed

This is the method I use to create the symbol and set the property: SYMBOL_VOLUME_MIN for the custom symbol.

(SetProperty(SName, SYMBOL_VOLUME_MIN , 0.001 , "" )
