Glad to see an answer. Means forum is alive.

Got this line in AssetsFix.txt file:

MATIC/USDT,0.730530,0.000150000,0.1665,-0.4580,0.00010000,0.10000,7.305,0,1000,0.0,MATICUSDT

As I understand - the really important bit is the last item that identifies symbol.

If I change it to anything else like this:
MATIC/USDT,0.730530,0.000150000,0.1665,-0.4580,0.00010000,0.10000,7.305,0,1000,0.0,MATICUSDT_INVALID

And try to download M1, Zorro says:
!BrokerHistory2: Symbol MATICUSDT_INVALID not found

If I change it back and try to download 2020-2021, whole thing runs smoothly but the both t6 files are only 47KB long.
They basically are empty.

If I try to download Ticks, it says:
Error 063: Tick history not available

--------------------

Tried to do whole thing manually.
Downloaded bunch of csv`s through binance api.
Did some cleanup so it looks like this:

Date,Open,High,Low,Close,Volume,QuoteVolume
26/04/2019 18:00:00,0.00263000,0.01052000,0.00263000,0.00639000,157258876.10000000,1092100.13082700

Modified CSVtoHistory script format to:
string Format = "%d/%m/%Y %H:%M:%S,f3,f1,f2,f4,f6";

And ran import. Seemingly successfully.

Ran CSVfromHistory to see what has made in and it looks decent:
2021-01-01T00:00:00,0.01742,0.01742,0.01742,0.01742,0.00000,5312.29980

But when I try to run Ehler's AMFM script or Workshop4 or Workshop5, it just says:
Error 047: No bars generated

Sometimes:
Error 042: no MATICUSDT parameters at walk 0
^ tried to change MATIC/USDT in assets list to MATICUSDT for the name too

And Zorro Chart Viewer says:
Unspecified error

Tried setting various StartDate and EndDate. Nothing changed.
Tried setting BarPeriod to 1, 5, 60. Nothing changed.

Why does it dislike that imported data?

Also - failed to find the log files. Tried to set LOGFILE flag but that produced nothing.
