I'm trying to download data using fetch function, but with some tickers I can't get the data.
For example:
When I try to download from TLEVISACPO.MX I get NaN's but the yahoo ticker is correct.
var =
Symbol: {'TLEVISACPO.MX'}
Last: 0
Date: NaN
Time: 0.7722
Change: NaN
Open: NaN
High: NaN
Low: NaN
Volume: NaN
This is one of the Tickers which I can download the data
>> var=fetch(yahoo,'GAPB.MX')
var =
Symbol: {'GAPB.MX'}
Last: 93.9000
Date: 735936
Time: 0.6729
Change: 1.2600
Open: 92.9200
High: 94.1100
Low: 90.6000
Volume: 1020912
Anyone know whats the problem?
With the next tickers I only get NaN's:
COMERCIUBC.MX, GSANBORB-1.MX, LIVEPOLC-1.MX, MFRISCOA-1.MX, NAFTRACISHRS.MX, etc.
I think the problem is the length of the ticker or the hyphen. If it is the problem, how can I solve it?
Thanks.

>> var=fetch(c,'TLEVISACPO.MX')
var =
