When the ERI lookup page analyses your trades, it will cache data so that if you repeat a similar run, it will be much quicker.

Your trade data is not cached. The server just stored the ISIN number of each ticker symbol, the historical Fx rates that it needs to look up on the Frankfurter API, the ERI rates of each ISIN number for each year, and it also fetches and copies source reportable income documents from provider websites (rather than fetching and parsing them each time).

If there is a problem with the cached data, I can clear the caches on request.

There is also an override database where I can correct any bad ERI error in source documents or provide ERI data if the original source documents have been removed by the provider.
