 ### Hyperopt checklist

 As hyperopt consumes a lot of memory (the complete data needs to be in memory once per parallel backtesting process), it's likely that you run into "out of memory" errors.
 To combat these, you have multiple options:
 
-* reduce the amount of pairs
-* reduce the timerange used (`--timerange <timerange>`)
-* reduce the number of parallel processes (`-j <n>`)
-* Increase the memory of your machine
+* Reduce the amount of pairs.
+* Reduce the timerange used (`--timerange <timerange>`).
+* Avoid using `--timeframe-detail` (this loads a lot of additional data into memory).
+* Reduce the number of parallel processes (`-j <n>`).
+* Increase the memory of your machine.

 ## The objective has been evaluated at this point before.
