Frequent lack of data for backtesting
The phenomenon noted repeatedly, affects many coins. Despite the existence of quotes on a given exchange at a given time, the system is unable to retrieve them.
The latest example - BRETT in 1 min intervals for Oct 25 - Nov 10.
The problem often noticed on Kucoin, on Bybit less often although it also happens.
