I have implemented a dedicated Postgres Server which hosts my database with all downloaded candles.
As i was redirecting my local PCs to the server i noticed the candle import function was pretty slow. I optimized the import function to make it much faster. It checks the number of candles in the database and only imports candles that are newer than the latest candle from the last import.
