+- `TRAILING_STOP_LOSS` - Set to `true` to use trailing stop loss.
+- `SKIP_SELLING_IF_LOST_MORE_THAN` - If token loses more than X% of value, bot will not try to sell
+  - This config is useful if you find yourself in a situation when rugpull happen, and you failed to sell. In this case there is a big loss of value, and sometimes it's more beneficial to keep the token, instead of selling it for almost nothing.
