I'm trying to download data using fetch function, but with some tickers I can't get the data.
When I try to download from TLEVISACPO.MX I get NaN's but the yahoo ticker is correct.
This is one of the Tickers which I can download the data
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?
