Please ensure the file you upload is in the correct format.

  • Allowed file extensions: .CSV (if using excel, you must save the file as .CSV)

  • All date formats in YYYY-MM-DD (days and months must use trailing zeroes, e.g. 2020-01-01)

  • The weights must be in decimal format, e.g. 2% -> 0.02

  • No column headers except for those specified in the samples below

  • Symbols must be mapped to the symbol mapping provided below

Step 3: Set your rebalancing specifics and benchmarks.

Step 4: Click “Create Backtest”.
