I'm looking to use Quantopian to help backtest daytrading strategies, but wasn't sure how quickly the data would be returned from an API call. If I make an API call at 9:41:00 to get the closing prices of the 9:40:00 1-minute candle, will I be able to process the data immediately at 9:41:00? And if I decide to place an order at 9:41:00 based on the data, would the order be filled immediately or at the next minute?
