I have issue importing stock data in txt format - any time frame (daily, minute). Futures (for example YM) are without any problems, but stock (for example AAPL, ETFs...) are not imported. I use the same procedure as for futures, but when trying to plot the chart, I see info "Not enough data available". Also when running backtest on imported stock data, I receive message "The symbol has no data".
Can someone advise?
