Please log the history request object first:
history = self.History(["AUDUSD", "USDSGD"], 200, Resolution.Daily) self.Quit(f'{history}')and you will be able to verify which columns are available in the pandas data frame.
Normally, "value" is not a column for historical request of Forex quote bars. You should use close instead:
history = self.History(["AUDUSD", "USDSGD"], 200, Resolution.Daily) self.Quit(f'{history["close"]}')Apollos Hill
