-### the `--live` command line option
+## Deprecated
 
-`--live` in the context of backtesting allows to download the latest tick data for backtesting.
-Since this only downloads one set of data (by default 500 candles) - this is not really suitable for extendet backtesting, and has therefore been deprecated.
+### the `--refresh-pairs-cached` command line option
 
-This command was deprecated in `2019.6-dev` and will be removed after the next release.
+`--refresh-pairs-cached` in the context of backtesting, hyperopt and edge allows to refresh candle data for backtesting.
+Since this leads to much confusion, and slows down backtesting (while not being part of backtesting) this has been singled out 
+as a seperate freqtrade subcommand `freqtrade download-data`.
+
+This command line option was deprecated in `2019.7-dev` and will be removed after the next release.
