Brazilian stocks candlestick graph becomes incorrect for ALL stocks and indexes when markets are closed
When Brazilian markets are closed (late night time in US) data on the latest trading day becomes corrupt in Yahoo finance. This happens for all stocks and indexes in the B3 market. This bug is not new and has been around for many months.
Prices become:
Open = 0.00;
High = 0.00;
Low = 0.00;
Close = correct closing price.
This results in a candlestick graph with a huge vertical green bar that completely distorts the graph, rendering it useless.
The next day, when trading resumes, the bug corrects itself and graphs show correctly again, only to repeat the bug again next night.
Some assets that can be used to verify the issue: cple6.sa, mglu3.sa, petr4.sa, bova11.sa and so on. Just pick anything from the bvmf market.
You will only see this bug if said graph is checked like 1 a.m. US time. The bug remains basically throughout all the night.
