Hi, going to backtest some strategies, therefore have some questions, could you please clarify them? 1) Is tradingview's Pine script ok? Have programmed several strategies and got some doubts that it isn't enough flexible for something more or less real 2) Where do you get intraday trading data to backtest your strategies from? Maximum that i got to download is ten days for 5 min interval. Ideally want to backtest using python Thanks!
