It is pretty important question, especially for investors with large portfolios. Plainzer provides several options to import transactions. The fastest way is to import transactions using CSV files, we support templates from the following brokerages: Charles Schwab, Robinhood, Webull, Trading 212, Revolut, XTB. You could also use our custom template. If your brokerage template is not supported yet, you could contact our support team. We also leave an option to create transactions manually without CSV files.
