Erratic stock price variation
I have just retrieved MGLU3.SA historical data and there are some huge discrepancies with reality. Among many other occurrences, between 2019-07-01 and 2019-07-10, closing prices from https://br.financas.yahoo.com/quote/MGLU3.SA/history?period1=1561939200&period2=1562716800&interval=1d&filter=history&frequency=1d , come as
2019-07-01 210.20
2019-07-02 212.46
2019-07-03 220.85
2019-07-04 27.64
2019-07-05 28.26
2019-07-08 229.40
2019-07-10 233.50
The issue is that the only correct prices are the ones for 2019-07-04 and 2019-07-05.
These jumps in price happen throughout its historical data and not only for this ticker. SQIA3.SA is suffering from the same problem.
What suprises me the most is that these discrepancies have not occurred until Feb 8th, when I retrieved them for the last time. At that time, they came like this:
2019-07-01 26.27
2019-07-02 26.56
2019-07-03 27.61
2019-07-04 27.64
2019-07-05 28.26
2019-07-08 28.67
2019-07-10 29.19
Does any one have a clue of what is going on? Thanks

Now it seems to get solved by itself...

Although it seemed to get solved by itself, on March and April, 2019, there are many of those problems...
