EasyStockDater has an excellent updating speed of existing databases.
This is made possible because it only fetches the missing data between the newest data in the database and today.
As for example, if you leave your trading office in the middle of the month for a two week vacation and come back at the end of the month, easyStockDater will only updated the two week missing data gap instead of re-downloading the whole data range..
Through this technique, not only the updating speed is better, also the load on the data transfer on the internet is kept at an optimum level. |
