Answer
Yes it will buy some from 0.7 to 0.6. If price keep decreasing, you will have negative unrealized profit because these bought token have less value from what its bought. But as long as the price come back to the price range and the bought token sold, you’ll get the profit.
It is suggested to start the bot at the lowest price you could make so you wont have to get big negative unrealized loss like your example.
