Requirements for the maximum data size and minimal time interval

CandleScanner accepts a data size up to 500,000 quotes (half million) per symbol, with the minimal time interval of 1 minute. This for most users probably more than sufficient. For example, 500,000 quotes are equal to:

  • 347 days of 1-minute time intervals
  • 83 years (assuming there is 250 trading days in a year) of hourly time intervals
  • 2000 years (assuming there is 250 trading days in a year) of daily data

In general, it is best to make sure that the loaded data sets are no larger than needed because, the larger the data to process the lower the performance of the application.
