At the risk of repeating a thread. This was a previous Q&A thread with support, who gave answers I didn't fully understand.

As support said in the previous thread (in a roundabout way).... NT8 can support 8 decimals (has to be 8.0.15 or later I think), however "custom" crypto instruments are treated as Stocks.

When you Custom Create a crypto pair, NT8 will create BOTH Crypto category & Stock Category instruments. However what NT8 DOES NOT DO is set BOTH tick sizes to 8 decimals.
So assuming you've created your Crypto cat pair to 8 decimals, you then need to edit the Stock category of the same name: Tick size to 8 decimals, 24 hour etc.
Without this extra edit, all imported prices will be ZERO.

Then when you try to open a chart, the Crypto cat symbol will be there, and the correct prices will also be there. (you can check in Historical Data).

I ended up deleting my "Crypto" category instruments, keeping the Stock cat instruments, but then there were no Instruments visible under "Instrument Lists" when trying to open a chart.
In this situation, easier just to ADD the Stock instrument into the Crypto CAT from from Instrument Lists.
(rather than laboriously clicking Add, you can just type in the symbol, and NT8 will auto bring up a dlg searching Master Database. Choose symbol from Stocks cat.)

Hope this helps. I can imagine someone else trying to do this, hence the post.

This is an expected symptom of creating a crypto instrument which contains a currency which is not in our supported list of currencies. As more currencies are added to that supported list, this will occur less frequently. Several new currencies, including XRP, will be added to the supported list soon.
